Quality filtration is equally as important as quality lubrication.

Mark Nyholm-  Technical Product Manager

Filters are often overlooked, but they are integral to keeping oil clean and performing at its best.

It’s often said that motor oil is the lifeblood of the engine. We depend on it to prevent wear, maintain cleanliness, minimize operating temperature and act as a seal. Should the oil become contaminated, its ability to perform these tasks can be greatly impaired. Dirty oil can cause piston ring wear, leading to increased oil consumption, and it can also accelerate wear in bearings and cylinders. Engine contaminants cannot be eliminated, but they can be controlled with proper filtration. Proper filtration helps keep oil clean and flowing freely, ensuring the lubricant will be able to perform its necessary tasks continuously.

At a basic level, all filters are designed to separate solid particles from air or fluid and keep them from entering into places where they are not wanted. Think about your morning coffee and what would happen if the coffee filter failed to keep the coffee grounds out of the brewed beverage. You would have very thick and sludgy coffee, not unlike the sludge that can build up in engines with severely contaminated motor oil. In the same way as coffee filters keep grounds out of your java, oil filters capture contaminant particles within the oil to prevent them from causing engine wear. This is important because contaminated oil can reduce engine life from 60 to 80 percent. You probably can see how a poorly designed filter could lead to an engine filled with gunk.

When discussing filters and filter performance at your next barbeque, make sure you talk about the four main criteria: flow, efficiency, capacity and particle size. Proper flow is important so oil can get to critical parts of the engine. If the filter creates an abnormal restriction of oil flow, it can lead to oil starvation and catastrophic engine damage. Efficiency is a measure of a filter’s ability to adequately remove contaminants of a particular size that may critically harm the application. The greater the efficiency, the better that filter is at removing contaminant particles. Capacity describes the amount of contaminants a filter can hold and still flow oil properly. Capacity is described as the service interval or useful life of the filter.

Most of these particles are smaller than what is visible with the human eye. Particles of greatest concern for most applications are 5-25 microns, which is smaller than the diameter of a human hair. Generally, if a filter has large openings, like a window screen, it will have poor efficiency but will flow very well. As screen holes get smaller, more small particles will get caught in the screen. The trade-off is that flow will be restricted. Balancing these two design features is an essential part of filter design.

The type of filter media used in a filter has a big impact on performance. Four major types exist in today’s marketplace, including open-celled foam, cellulose, cellulose/synthetic composite and full synthetic. Synthetic filter media has several advantages over the other filter media materials. Synthetic media has higher capacity and can be modified to a wide range of efficiencies. Synthetic media also removes smaller contaminant particle sizes, and is suitable for extended service intervals because of the increased capacity for contaminants. It is also typically more durable than other filter media, like paper-based materials that use sticky resins to keep fibers from falling apart over time. Cellulose media used in lower-quality filters have larger fibers and bigger holes that let more contaminants pass through the filter. Synthetic filter media is chemically manufactured rather than derived from a tree, like paper, so the fibers are much smaller and specifically designed to capture smaller particles while still keeping good flow of oil through your engine. Ah, the magic of synthetic materials.

AMSOIL incorporates synthetic media into AMSOIL Ea® Filters, which rank among the highest-efficiency filters available. Better filtration equals reduced engine wear. In addition, the extra capacity to hold more contaminants means they keep filtering over extended intervals. When used in conjunction with AMSOIL synthetic motor oil, AMSOIL Ea Oil Filters designated with product code EaO are guaranteed for 25,000 miles/ one year (15,000 miles/one year in severe service). Smaller Ea Oil Filters designated with product code Ea15K are guaranteed for 15,000 miles/one year in normal and severe service. Good oil and good filtration go hand in hand, and AMSOIL Dealers have the products to offer the best of both to their customers.

Maximum Hydraulic System Protection

Certain hydraulic systems, including those installed in log splitters, skid steers and small tractors, are often operated seasonally or intermittently, then stored for extended periods. Although checking and changing hydraulic oil is sometimes an afterthought, fluid maintenance is important to ensure optimum protection and performance and maximum equipment life. AMSOIL synthetic hydraulic oils can provide significant benefits and cost savings over conventional hydraulic oils.

Reduced Heat

The synthetic construction of AMSOIL synthetic hydraulic oils can reduce heat in hydraulic systems, leading to better viscosity retention; less varnish build-up, oxidation and component wear (including hoses); longer seal life; and better overall system performance.

Cold-Weather Performance

Mobile hydraulic equipment often sits in the elements while on a job site, causing many conventional hydraulic oils to thicken in the cold and lead to equipment damage such as excessive pump wear due to cavitation, blown hoses, broken shafts and extended warm-up times that waste fuel. AMSOIL synthetic hydraulic oils are formulated for better coldtemperature characteristics than petroleum oils, helping reduce or eliminate many of these issues.

All-Season Functionality

To eliminate some of the problems associated with temperature changes, many mobile hydraulic equipment owners switch oil viscosities with the seasons. AMSOIL synthetic hydraulic oils are high-viscosity-index formulations that can eliminate the need for seasonal changes. It's possible to run an AMSOIL ISO 32 or ISO 46 hydraulic oil successfully year-round in all but the most extreme cold conditions.

Hose Life Preservation

Cold and heat wreak havoc on hydraulic system hoses and seals. Cold, thick fluid can cause pressure spikes and extremely hot fluid breaks down hoses and seals over time, leading to leaks and wasted hydraulic fluid. The superior cooling and flow properties of AMSOIL synthetic hydraulic oils help preserve hose integrity.

AMSOIL Synthetic Anti-Wear Hydraulic Oil

AMSOIL Synthetic Anti-Wear Hydraulic Oil effectively inhibits oxidation to help prevent acid formation and viscosity increase, resist carbon and varnish deposits and inhibit rust and foam (providing smooth hydraulic operation). It contains an effective zinc-based antiwear/ antioxidant additive that controls wear in high-speed, high-pressure vane and gear pumps while meeting the lubrication requirements of axial piston pumps with bronze-on-steel metallurgy.

• Maximum cold-temperature performance
• Formulated for long life
• Superior anti-wear protection
• Contains rust, oxidation and foam inhibitors
• Hydrolytically stable and readily separates from water
• Available in ISO 22, 32, 46 and 68 viscosity grades

AMSOIL Synthetic Multi-Viscosity Hydraulic Oil

It contains antioxidants that prolong oil life and foam inhibitors that help promote problem-free operation.

The Importance of Proper Lubrication to Automotive Seal Life

Although most motorists don’t think about them unless they notice a fluid leak, vehicles contain several different seals responsible for retaining lubricants within the system and keeping contaminants out. Seals are also responsible for confining pressure and keeping lubricants separated. Familiar locations include the crankshaft, transmission output shaft and axles. Made primarily of elastomers (synthetic rubber), modern seal materials offer increased performance and life. But age, high mileage and storage can lead to drying and hardening, causing shrinking, cracking or tearing. In addition to fluid leaks, damaged seals can allow dirt and other contaminants to enter the system, negatively affecting performance.

In the 1930s, manufacturers pioneered the custom manufacturing of elastomers. Common seal materials today include nitrile (buna-N [NBR]), neoprene, silicone, ethylene acrylic, polyacrylate and fluoroelastomer. Each material offers different strengths and weaknesses throughout different temperature ranges.

Nitrile seals, better known as buna-N (NBR), are common in automotive applications due to their low cost and good resistance to oil, water, grease and other substances. However, NBR offers poor resistance to ozone and weather aging. Ethylene acrylic and polyacrylate are often used in transmission and power steering units.

Wherever seals are installed and whatever they are made of, proper lubrication is required to maximize life and performance. Seal compatibility is achieved by selecting the proper base oils and additives that cause seals to swell at a slow, controlled rate over their usable lives. This allows the seal material to take the place of worn material to prevent premature leakage. Seal conditioners help keep seal materials supple to prevent them from becoming brittle and causing leaks. For example, valve seals prevent oil from entering the cylinder during the intake stroke. A dry, brittle seal may allow oil to leak past the seal and burn during combustion, causing the engine to use oil.

Years ago, many erroneously believed synthetic oils were too slippery and leaked past seals. However, field studies and real-world use by countless motorists prove otherwise. Put to the test in a Las Vegas taxi cab driven over 100,000 miles in severe service, AMSOIL Signature Series 0W-20 Synthetic Motor Oil (ASM) and AMSOIL Signature Series Multi-Vehicle Synthetic Automatic Transmission Fluid (ATF) delivered excellent protection for seals and offered reliable, no-leak protection. See the Las Vegas Taxi Cab Field Study (G3118) for details. AMSOIL synthetic lubricants are formulated and tested to be fully compatible with modern seal materials. They deliver excellent seal protection and compatibility, helping them function properly throughout their service lives.

Keeping Engines Clean with AMSOIL

Though conventional motor oil quality has improved over the past 30 years, this progress is also offset by emission-reduction strategies, including variable valve timing (VVT), which strangles the engine a little tighter and makes it run hotter.

The average motorist has never even heard of variable valve timing, but it’s a critical component in the operation of a vehicle. Almost every vehicle manufacturer has published a bulletin stating that the number one cause of variable-valve-timing system problems is small amounts of residue and sludge. In other words, cleanliness is absolutely essential.

In the old days, the engine’s intake and exhaust valves were set to open and shut at specific points in the four-stroke cycle for a set amount of time. With variable valve timing, engines can adjust the timing for when and how long these valves open and shut by relying on a combination of sensors and mechanical systems, many critically located on the camshaft and crankshaft. When these components get gummed-up with sludge or deposits, it can lead to poor performance and costly repair bills.

Because AMSOIL synthetic motor oil resists oxidation and breakdown in high heat, it is less prone to produce the varnish and sludge that damages these critical sensors.

Keeping engines clean by using AMSOIL synthetic motor oils helps them last longer. Cleanliness reduces wear, ring sticking and emissions while helping ensure all these components operate as designed.

AMSOIL SYNTHETIC MOTORCYCLE OIL DELIVERS WHAT BIKERS WANT

According to an industry survey, U.S. bikers value engine  protection and quality above all else.

Click for larger image

Over 80 percent of survey respondents rate engine protection and quality as important or very important when selecting motorcycle oil. Viscosity grade and motorcycle specific formulations are also important or very important to a majority of respondents. Interestingly, price was the sixth most important factor, indicating most bikers are willing to pay a premium for motorcycle oils that help them get the best performance and most years from their engines. Results indicate what motorcyclists want in a motor oil is exactly what AMSOIL Synthetic Motorcycle Oil delivers.

Keeping Bikes Longer

The demographics of the U.S. motorcycle fleet may have played a large role in how bikers responded to the survey. Sales of new bikes, as reported by the Motorcycle Industry Council, reached 452,400 in 2012. However, over half of the 10 million bikes in the U.S. fleet are more than seven years old while almost 25 percent predate 1995. Bikers are keeping their motorcycles longer and selecting lubricants that help them do so by maximizing engine protection and longevity.

MOTORCYCLE SPECIFIC FORMULATIONS

Bikers also value motor oils formulated specifically for motorcycles  demonstrating that many understand the unique challenges motorcycles present to lubricants and the need to use lubricants formulated to meet those challenges. Motorcycles run hotter and at higher RPM  than passenger cars/light trucks – conditions that require robust oils formulated to resist viscosity loss due to extreme heat and mechanical shear. In many bikes, the oil must lubricate the engine, transmission and primary chaincase simultaneously. Effectively protecting against engine and gear wear while delivering superior clutch performance requires a balanced oil tailored to protect all critical areas. Passenger car/light truck motoroils simply aren’t designed to meet the needs of motorcycles. However, 59 percent of respondents indicated an API-certified oil was very important or important, indicating there is still limited knowledge of lubricant specifications and their applicability.

Synthetics on the Rise

Click for larger image

Full-synthetic oils rate as important or very important to 42 percent of respondents. Where bikers once had to be convinced of synthetics’ superiority, many now understand synthetics are better-suited to protect their engines in the toughest riding conditions. The survey also found that the strength of brand reputation and explicit product quality claims are two key differentiators in the market. The AMSOIL brand signifies industry leading quality due to the company’s presence at the largest and most influential motorcycle rallies in North America – including Sturgis, Daytona Bike Week and Laconia Motorcycle Week – and its sponsorships in the motorcycle racing markets – including AMSOIL Arenacross, Erik Buell Racing, Monster Energy Supercross and Loretta Lynn’s AMA Amateur National Motocross Championships.

More importantly, AMSOIL Synthetic Motorcycle Oil lives up to its performance claims delivering real world benefits experienced by countless bikers. Formulated specifically to meet the demands of motorcycles, its exceptional high temperature film strength provides maximum wear protection. AMSOIL Synthetic Motorcycle Oil promotes superior engine cleanliness, wet-clutch performance and transmission protection. Its performance has earned AMSOIL Synthetic Motorcycle Oil a strong reputation for quality, delivering the performance bikers want.

Solving the Challenges of Flat-Tappet Cams in Classic Car Engines

Summer belongs to classic cars and hot rods. It's the season when thousands visit car shows across North America and loyalists of every make and model cruise the streets to show off their rides. One of the big concerns among classic car owners in recent years, however, has been the abundance of flat-tappet camshaft failures that many attribute to the reduction of zinc and phosphorus in today's oil formulations.

Zinc dialkyldithiophosphate (ZDDP) is the most common zinc-based additive, and is used primarily as an anti-wear agent to prevent premature engine wear. It also provides corrosion and oxidation protection. However, because the zinc and phosphorus found in ZDDP can negatively affect catalytic converters, it has been phased out of motor oil formulations in recent years.
Reducing ZDDP content has drawbacks, as classic car owners have found. Older vehicles with flat tappet camshafts and, in particular, engines that include high-tension valve springs or other modifications that create high contact pressures can suffer premature wear due to reduced ZDDP levels.

Flat-Tappet vs. Roller Cams

The design of flat tappet cams makes them especially vulnerable to wear. As the name indicates, the tappet - or lifter - is flat. During operation, the surface of the cam lobe slides rapidly over the surface of the tappet, producing high friction and temperatures. A thin oil film is the only barrier that prevents the lifter and cam lobe from welding together. If the oil film fails or provides insufficient wear protection, the two components can eventually wear the flat tappet cam and affect valve operation. Engine power and efficiency can decline if the flat tappet cam cannot lift the valves enough to adequately charge the chamber for ignition or release exhaust fumes. Because most V8 engines of the muscle-car era came standard with flat tappet cams, the problem is especially prevalent to classic-car and hot-rod owners.
Roller cams, on the other hand, are differentiated by rolling contact rather than sliding contact. Although more costly, roller cams are common in most modern vehicles and can be retrofitted into classic-car and hot-rod engines.

AMSOIL Signature Series Synthetic Motor Oil Outperforms Competition in New Study

Nine synthetic motor oils were compared to AMSOIL Signature Series 5W-30 Synthetic Motor Oil (ASL). When it was all said and done, Signature Series demonstrated the best overall performance and cost-effectiveness.

Click for larger image

Since AMSOIL introduced the first synthetic motor oil to meet American Petroleum Institute (API) service requirements in 1972, many other synthetic motor oil brands have been introduced. Today, synthetics are widely viewed as superior to conventional motor oils, and demand continues growing, but how do other brands compare to AMSOIL?

A Study of SAE 5W-30 Synthetic Motor Oils

Signature Series 5W-30 Synthetic Motor Oil and nine other synthetic oils were subjected to five industry tests conducted according to American Society of Testing and Materials (ASTM) methodology. The overall annual cost of each oil was also compared. The study included synthetic motor oils exclusively for a number of reasons. First, most motorists now understand that synthetics provide increased performance benefits compared to conventional oils, so convincing consumers of synthetics' superiority is less of an issue. Second, while conventional motor oil sales remain flat, demand for synthetics continues to increase. Third, testing only synthetics facilitates an apples to apples comparison.

Methodology

Testing examined several important areas of motor oil performance, including resistance to deposit formation, wear protection, high-temperature stability, resistance to acid formation and cold temperature performance.

Click for larger image Four-Ball Wear Test results indicate significant differences in relative wear protection between oils. The top four performers limited wear scars to under 0.40 mm. AMSOIL Signature Series Synthetic Motor Oil demonstrated the best wear protection in the Four-Ball Wear Test.

• NOACK Volatility Test (ASTM D 5800)
• Four-Ball Wear Test (ASTM D 4172 Mod.)
• Total Base Number (ASTM D 2896)
• Cold Cranking Viscosity (ASTM D 5293)

Test results published in A Study of SAE 5W-30 Synthetic Motor Oils describe and represent properties of oils that were acquired from November 2012 to December 2012. Results do not apply to any subsequent reformulations of such oils or to new oils introduced after completion of testing. All oils were available to consumers at the time of purchase. An independent, third-party lab conducted all tests. Formulations were coded to reduce the potential for bias, and samples were tested in random order. An appropriate number of trials of each oil were run to produce results at the 95 percent confidence level when compared to Signature Series Synthetic Motor Oil. The 95 percent confidence level only applies when comparing AMSOIL Signature Series Synthetic Motor Oil to the other 5W-30 oils. The 95 percent confidence level does not apply when comparing the other oils to one another.

The following nine oils were selected for the study:

• Castrol Edge® with Titanium Fluid Strength Technology®
• Lucas Synthetic
• Mobil 1™ Extended Performance
• Pennzoil Ultra™
• Petro-Canada SUPREME Synthetic™
• Quaker State Ultimate Durability™
• Red Line High Performance Motor Oil
• Royal Purple High Performance Motor Oil
• Valvoline SynPower® Full Synthetic Motor Oil

All oils are 5W-30 viscosity and recommended for applications requiring API SN/ILSAC GF-5 specifications.

Results

AMSOIL Signature Series Synthetic Motor Oil displayed the best results in the Four-Ball Wear, Total Base Number and Cold Crank Viscosity Tests. Results in the NOACK and TEOST Tests were also impressive, proving Signature Series Synthetic Motor Oil's excellent high-temperature performance. Other oils performed well in some tests, but not as well in others, illustrating the challenge inherent in formulating a high-quality motor oil that performs well in tests designed to assess optimum engine protection and life. In addition to delivering outstanding performance, Signature Series Synthetic Motor Oil provides maximum cost-effectiveness - even at retail pricing. Because they buy at wholesale, Dealers and Preferred Customers receive even more value. In the end, no other oil demonstrated itself capable of providing the overall performance in these tests and cost effectiveness of Signature Series.

AMSOIL Synthetic Lubricants Proven in Las Vegas Taxi Fleet Field Trial

Click for information at AMSOIL.com

With modern vehicles producing increased heat, the ability of lubricants to protect against sludge and deposit formation is becoming more important. Motor oils and transmission fluids must demonstrate increased thermal stability throughout longer drain intervals for components to last as designed.

AMSOIL synthetic lubricants are formulated with reserve protection to withstand heat and its negative effects. To demonstrate it, AMSOIL Signature Series Synthetic Motor Oil and Signature Series Synthetic Automatic Transmission Fluid were put to the test in taxi cabs operating in the searing desert heat of Las Vegas, Nev.

Taxi Fleet

Taxis are notoriously hard on lubricants due to excessive idling and constant stop and go driving loaded with passengers and cargo. Las Vegas summer temperatures added to the challenge, topping 100ºF during this field study.

Six vehicles operated with AMSOIL synthetic lubricants for 18 months. The vehicle selected for further analysis – a 2010 Dodge Charger equipped with a 2.7L V6 engine and 4-speed automatic transmission – accumulated 7,033 hours (102,582 miles) prior to the engine and transmission disassembly. Given the unusually high amount of idle time, maintenance intervals were determined in hours rather than miles. Signature Series 0W-20 Synthetic Motor Oil (ASM), changed every 900 hours or approximately 15,000 miles, was used in the Charger’s engine, while the transmission used Signature Series Multi-Vehicle Synthetic Automatic Transmission Fluid (ATF), which was not changed during the study.

The Charger operated throughout Las Vegas up to 24 consecutive hours each day, with the engine shut down only during refueling and personnel changes. Average speed was 14.6 mph, while the EPA indicates the average speed for city driving is 21.2 mph, illustrating the excessive amount of idle time and stop and go driving.

Results

Transmission components prone to the effects of lubricant failure, including the valve body and clutch plates, revealed virtually no sludge and little wear after operating 7,033 hours (102,582 miles) on a single fluid change. Although the Charger carried a recommended transmission fluid change interval of 60,000 miles in severe service, Signature Series Multi-Vehicle Synthetic ATF continued providing superior protection well beyond the severe-service recommendation, confirming its ability to provide reserve protection.

Engine components susceptible to the formation of harmful sludge, including the oil pan, oil pickup tube and cylinder heads, revealed virtually no sludge, earning high ratings from an independent calibrated rater. Results prove the ability of Signature Series Synthetic Motor Oil to safely extend drain intervals in severe service. Complete results are available in the Las Vegas Taxi Fleet Field Study (G3118) available from AMSOIL Inc.

Natural gas is an up-and-coming alternative to gasoline and diesel.

From stationary engines to heavy-duty equipment and even passenger cars, natural-gas engines are becoming more prominent.

Mark Nyholm | Technical Product Manager - Heavy Duty - AMSOIL Inc.

 Alternative fuels have been the talk of the town for over 10 years now, and the quest to reduce engine emissions, fuel costs and dependence on foreign oil often leads to fuels other than gasoline or diesel. Natural gas is one of these upand-
coming alternative fuels. For many of us, natural gas heats our homes and runs our stoves, water heaters and clothes dryers. This low-carbon fuel is making its way to powering a variety of natural gas engines for both stationary and vehicular applications. Compared to the relatively complex chemical structures of gasoline and diesel, natural gas has a relatively simple chemical makeup primarily composed of methane. When natural gas is burned, it produces fewer pollutant emissions than coal or petroleum products, which makes it a natural choice on the quest to reduce engine emissions.

Three varieties of natural gas are used: compressed natural gas (CNG), liquefied natural gas (LNG) and renewable natural gas (RNG) or biomethane. CNG is natural gas compressed into high-pressure containers for storage or transport. LNG is achieved by cooling natural gas to -260°F at atmospheric pressure. LNG is 1/600th the volume of natural gas at atmospheric temperature and pressure, making it ideal for applications that are
weight or space limited. Biomethane, or biogas, is a naturally occurring, renewable energy source created by the breakdown of organic matter, such as farm and landfill waste. This low-carbon organic waste can be processed to high-quality natural gas suitable for use in pipeline or a variety of stationary and vehicular engines.

Vehicular natural gas engines are used in many mobile applications, including public transit buses, refuse haulers, delivery trucks, school buses and many other medium-/heavy-duty trucks. Natural gas has even made its presence into a few small passenger vehicles such as the Honda Civic; and Ford, General Motors and Ram have natural-gas-powered light-duty pickup trucks. Because of the limitations in engine availability, the heavy-duty market is primarily where natural gas is being used today. The limited number of natural-gas filling stations has also put constraints on the expansion of applications outside of engines either directly connected to the natural-gas pipeline or to vehicles that return to base daily. So if you are looking for natural-gas-powered vehicles, think locally and look at medium- to heavy-duty applications performing duties similar to diesel-powered vehicles.

Nearly all the natural gas used in North America is produced domestically, allowing local control over the energy supply. The cost of natural gas is substantially less than diesel or gasoline, resulting in reduced fuel costs. Many cities and states are looking to natural gas for two main reasons: First, natural gas engines are much quieter than their diesel counterparts. An idling diesel engine can be up to 10 times louder than a natural-gas engine. Because these engines often operate in the public sector, reducing engine noise creates more peaceful environments for operators, passengers and bystanders alike. Second, natural gas produces lower levels of nitrogen oxides and particulate matter emissions than diesel. Complying with the emissions regulations set forth by the Environmental Protection Agency (EPA) or the California Air Resources Board (CARB) has become essential to conducting business in North America.

Natural-gas engines have specific lubrication demands that differ from those of diesel and gasoline engines. AMSOIL continues to be at the forefront of natural gas engine lubrication and is involved in various natural-gas organizations. We have run multiple field trials proving our superior lubrication chemistry, and we continue to strive to improve lubrication for these engines through analytical and laboratory testing. AMSOIL Synthetic Vehicular Natural Gas Engine Oil (ANGV) and AMSOIL Synthetic Stationary Natural Gas Engine Oil (ANGS) both feature a low-ash formulation to minimize deposits that can lead to engine knocking and valve recession, while anti-wear additives provide excellent wear protection. Their thermal stability minimizes oxidation, and their low volatility reduces oil consumption. With oil analysis, both are proven for use in extended-drain-interval applications.

Although natural-gas vehicles currently represent a small percentage of the overall vehicle market, steady growth over the next decade is expected. A study from Pike Research (a research and consulting firm focusing on clean technology markets) forecasts worldwide sales of natural-gas trucks to grow at a compound annual growth rate (assuming a steady rate of growth much like the rate of return on an investment) of 14 percent between 2012 and 2019. The vehicular natural-gas market represents another arena of opportunity for AMSOIL Dealers, now and in the future. Remember, although these heavy-duty engines are similar to diesel engines, they do come with some very important differences that you should be aware of. Take a little time some evening and Google “natural-gas vehicles.” Prepare to be astonished at the quantity of information about natural gas that has made its way into our lifestyles already.

AMSOIL Synthetic Motorcycle Oil Demonstrates Outstanding Protection in Extreme Heat

Protection against extreme heat is of the utmost importance in motorcycle applications. The aircooled V-twin engines used in Harley-Davidson motorcycles can get extremely hot, particularly when idling or traveling at low speeds.
If a motorcycle oil cannot withstand hot operating temperatures, its ability to provide adequate engine protection is compromised. AMSOIL Synthetic Motorcycle Oil is formulated to withstand extreme heat conditions beyond the hottest temperatures motorcycles typically experience, providing peace of mind that motorcycles receive outstanding protection and performance no matter how extreme the operating conditions.

Dynamometer Testing

To demonstrate its extreme-heat protection qualities, AMSOIL 20W-50 Synthetic Motorcycle Oil (MCV) was subjected to a dynamometer test designed to simulate conditions even more extreme than the demanding stop-andgo driving conditions of a motorcycle rally or parade route.
A 2012 Harley-Davidson FXDB Dyna Street Bob motorcycle equipped with AMSOIL 20W-50 Synthetic Motorcycle Oil was operated for 68.5 minutes at low speeds, with significant idle time broken by engine revving. Like most Harley- Davidson motorcycles, the Dyna Street Bob features an air-cooled V-twin engine, which relies on cooling fins arrayed along the cylinder walls to conduct heat away. To create the most-severe operating conditions possible, the electronic temperature controls, which safeguard the motorcycle when temperatures reach dangerous levels, were deactivated. The test subjected the oil and engine components to intense heat not normally experienced in the real world, with cylinder temperatures reaching more than 500°F.
The extreme temperatures were no match for AMSOIL Synthetic Motorcycle Oil. After nearly 70 minutes of torturous testing and heat exposure, oil analysis revealed no change in oil viscosity and only minor levels of oxidation, TBN depletion and wear.
Not only did AMSOIL Synthetic Motorcycle Oil prevent the engine from overheating and seizing, it did so without losing chemical integrity or ability to protect vulnerable engine components, demonstrating that it provides outstanding protection even in compromising and severe high-temperature riding and idling conditions not experienced by most riders.

 As temperatures climbed to more than 500°F in the cylinders, an infrared camera revealed the redhot conditions that assaulted the engine components and oil.

Viscosity

As heat breaks oil down, the viscosity typically rises until it is significantly out of grade and must be changed. AMSOIL 20W-50 Synthetic Motorcycle Oil showed no change in viscosity following the extreme-temperature test, demonstrating its outstanding resistance to thermal breakdown and its ability to provide excellent protection in the most severe conditions.

After 1.6 Million Miles 18 Wheeler Shows No Signs of Quitting

After 1.6 million miles on the original drivetrain and 1.1 million on the factory-rebuilt engine, Jerry Pruett and his AMSOIL-lubed Kenworth show no signs of retiring.

When AMSOIL Dealer Jerry Pruett of Woodhull, Ill. purchased his new 1999 Kenworth over-the-road truck in December 1998, he thought it might run forever if he installed AMSOIL synthetic lubricants. Now with more than 1.6 million miles on the drivetrain and over 1.1 million on the factory-rebuilt engine, "forever" still remains in sight.
The mileage is even more impressive considering how little work the truck has required. The Detroit Diesel Reliabilt^® engine still has virtually all of its original components, including the turbo and fuel injectors. The truck accumulates 2,300-3,000 miles a week hauling loads averaging 27,000-35,000 pounds, with some up to 80,000.
The reliability of the drivetrain is also notable. Though the clutch has been replaced a couple times, the transmission hasn't been touched. "I've done nothing to the transmission. All the gears in it are at 1.6 million miles," said Pruett. The differential gears are also original to the truck.
Pruett runs SAE 60 Super Heavy Weight Synthetic Racing Oil (AHR) in the transmission. He uses Severe Gear^® SAE 190 Synthetic Gear Lube (SRN) in the differentials, although AMSOIL primarily recommends 75W-90 Long Life Synthetic Gear Lube (FGR) in over-the-road applications. "A little bit thicker oil couldn't hurt with the high miles," said Pruett.

AMSOIL Helps Increase Life of Defective Engine

The truck was originally equipped with a Detroit Diesel engine that, unknown to Pruett, contained a manufacturing defect known to cause catastrophic failure early in the engine's service life. Pruett initially installed Shell Rotella during the break-in period. "I wanted the rings to seat prior to switching to AMSOIL," he said. At about 140,000 miles, he installed Series 3000 Synthetic Heavy Duty Diesel Oil (HDD).
With 506,000 miles on the engine, the number three piston failed. "In talking with the mechanics, I found out there was a defect on these engines, and some blew around 300,000 to 375,000 miles," said Pruett. "In one instance, a rod came through the engine and punctured the computer. I felt my engine lasted as long as it did because of AMSOIL." When the mechanics removed the cylinder heads, the original hone marks were still visible on the cylinder walls. "The mechanic said the engine was not wearing out; the oil was doing a great job. Had it not been for the piston failure, it could have run forever."

Detroit Diesel Reliabilt^® Engine

Despite the engine warranty having expired 6,000 miles earlier, Pruett presented his case to Detroit Diesel. "I felt Detroit Diesel was taking advantage of me. Other guys using any old oil were receiving warranty coverage because their engines failed sooner. I told them I was using the best oil in the world and, because of that, the engine lasted longer," said Pruett. "To have that engine last past the warranty was a surprise to them, I think." Detroit Diesel agreed to provide Pruett a factory-overhauled engine at cost, in addition to $4,500 for installation.
The factory-rebuilt engine has since powered the truck for 1.1 million miles, requiring virtually no repairs. "I haven't even pulled the cylinder head off this thing," Pruett said. "I didn't replace the water pump until accumulating over 900,000 miles. Usually a water pump lasts 350,000 miles on a good day." As with the previous engine, Pruett installed Shell Rotella during the break-in period prior to switching to Series 3000 Synthetic Heavy Duty Diesel Oil.
The lone repair required was replacement of the camshaft at about 100,000 miles, barely out of the break-in period when still using Shell Rotella. Pruett believes the camshaft was original to the engine and not replaced when the engine was factory re-built by Detroit Diesel.
With close to 800,000 miles on the engine, Pruett switched to higher-viscosity 15W-40 Synthetic Heavy Duty Diesel and Marine Oil (AME) to guard against excess oil consumption common as engines age.
During a routine 31-point inspection completed when Pruett had a faulty sensor replaced, the mechanic remarked how nice the turbo looked. "They thought it had only been in for a couple months," said Pruett. "It was 12 years old." Pruett credits the Donaldson Endurance™ Heavy-Duty Air Filter for the turbo's longevity. "I was sold on the air filter from day one," he said. "Throttle response was quicker, it boosted the horsepower a little bit and turbo noise decreased."

100,000-mile Oil Changes

Pruett also uses the AMSOIL DUAL GARD^® By-Pass Oil Filtration System fitted with two EaBP110 By-Pass Oil Filters. Regular oil analysis continually indicated the oil was suitable for continued use, allowing Pruett to establish an oil change interval of once per year, or about every 100,000 miles, based on historical data. The EaBP110 By-Pass Oil Filters are changed twice a year, or about every 50,000 miles. Practicing extended drain intervals saves a considerable amount of money each year compared to using conventional oil and standard drain intervals. "Some guys are spending up to $1,200 a year on oil changes when they could be spending half that with AMSOIL," said Pruett. "They're throwing their money away."

Excellent Fuel Economy

Additional savings are realized each time Pruett fills his diesel tanks. "The truck really kind of scares me; it runs so good. I'm still getting about 7 mpg," said Pruett. During a run from Indianapolis, Ind. to St. Louis, Mo., the truck achieved 9.7 mpg. "The truck is capable of that mileage if I can just keep my foot out of it," said Pruett. He has used AMSOIL Diesel Concentrate (ADF) since day one, which not only helps fuel economy but, according to Pruett, has contributed to the fuel injectors lasting as long as they have. He also keeps AMSOIL Cold Flow Improver (ACF) on hand and uses it when conditions dictate.

No End in Sight

Pruett's truck serves as a rolling billboard for AMSOIL. It's covered in AMSOIL decals, along with the contact information for Pruett's AMSOIL Dealership. He shares his AMSOIL story with truckers at every opportunity. Pruett turns 62 in January and has thought about retiring, but, unfortunately for him, his truck has not. "I really want to see how far this truck can go, so I keep on trucking away."

Reading a Product Data Bulletin: Viscosity

A lubricant's viscosity and how it changes under different temperatures and operating conditions is one of the most important properties determining performance and protection. Accordingly, Kinematic viscosity is generally the first property listed on an AMSOIL product data bulletin.
Kinematic viscosity, measured using ASTM D 445 methodology, determines an SAE oil's hightemperature viscosity grade (for example, the "30" in 5W-30), while its Cold Crank Simulator (CCS) viscosity, measured using ASTM D 5293 methodology, determines its low-temperature grade (the "5W" in 5W-30).

Why Two Different Test Methods?

Viscosity can be viewed in two ways. Kinematic viscosity is defined by the lubricant's resistance to flow and shear due to gravity. To illustrate, imagine pouring two containers, one filled with water and the other with honey. The rate at which each fluid flows is governed by its Kinematic viscosity. Since the Kinematic viscosity of water is lower, it flows faster.
Dynamic (or absolute) viscosity, measured by the CCS test, is defined as the lubricant's resistance to flow as indicated by its measured resistance, best thought of as the amount of energy required to move an object, such as a metal rod, through the fluid. It takes less energy to stir water compared to honey because the dynamic/ absolute viscosity of water is lower.
Each test method is designed to replicate a specific operating condition, allowing formulators and end-users to determine the lubricant's characteristics when in use. The CCS viscosity test evaluates the amount of energy it takes to start an engine at a specified cold temperature; the lower the viscosity grade, the lower the temperature at which the test is performed. The test assigns a value in centipoise (cP), used to determine the viscosity grade. Using Signature Series 5W- 30 as an example, its viscosity at -30ºC (-22ºF) can be no greater than 6600 cP to receive a 5W grade (see chart). Lower values reflect lighter-viscosity oils.
The Kinematic viscosity test attempts to simulate viscosity at normal operating conditions for a passenger car/light truck. The test is performed at 100ºC (212ºF) and/or 40ºC (104ºF), depending on the grading system being used. The value at
100ºC is used to determine the SAE viscosity grade. The test measures how long the oil takes to completely flow from a viscometer device heated to 100°C. The elapsed time in seconds is converted to centistokes (cSt). Lower values reflect lighter-viscosity oils.

Viscosity Index

The viscosity index (VI) of a lubricating fluid refers to how much the viscosity of the fluid changes due to temperature. A high VI indicates the fluid undergoes little viscosity change due to temperature fluctuations, while a low VI indicates a relatively large viscosity change. The Viscosity Index Test (ASTM D 2270) is based on the Kinematic viscosity of the fluid at 40°C (104°F) and 100°C (212°F). A fluid whose viscosity does not change much between these two temperatures will have a higher VI than a fluid whose viscosity change is greater. Viscosity index numbers above 95 are considered high. Fluids with a high VI provide more protection to critical components over a wide range of temperatures by maintaining fluid thickness and the necessary fluid barrier between parts.
