Sludge or Slime in the Radiator

 What causes radiator sludge/slime and what can you do about it?

• Additives dropping out: Coolant consists of a base (typically ethylene glycol or propylene glycol) mixed with additives and water. The base is primarily responsible for providing freeze and boil-over protection. The additives guard against corrosion, cavitation and scaling. Mixing of incompatible coolants can cause the additives to “drop out” of the solution and form sludge or slime.

• Contaminated coolant: A bad head gasket or cracked cylinder head can allow oil and coolant to mix, resulting in sludge. In vehicles with automatic transmissions, the engine-cooling system also cools the transmission. A breach in the system can contaminate coolant with transmission fluid.

• Corrosion: Occurs when an imbalanced coolant chemically reacts with metallic surfaces, forming reddish deposits that can appear as sludge or slime. 

Low-quality coolants can lead to cooling-system corrosion.

Performing fluid analysis is the only way to definitively identify what’s causing sludge/slime in your radiator. The report can identify oil, transmission fluid or other contaminants in the coolant.

Fix any mechanical defects and flush the cooling system. Refill with a high-quality antifreeze/coolant.

What kind of coolant should I use? 

Let’s start with what kind you should avoid.

You’re no doubt familiar with the conventional “green” coolants found at most retailers due to their low price. They contain inorganic salts, such as nitrites, phosphates and silicates.

Inorganic salts deplete quickly – typically in two years or less – and are on the environmental watch list. Once depleted, they are the source of common cooling-system problems, like scale deposits and sludge/slime.

Low-cost “green” coolants are the source of several problems, such as radiator sludge/slime and scale deposits.

For these reasons, most vehicle manufacturers have moved away from inorganic salts. 

And so should you. 

Instead, use a high-quality coolant that uses organic-acid technology (known as OATs). OATS coolants are much more robust and longer-lasting. They virtually eliminate drop-out, scaling and compatibility issues inherent to inorganic salts. This type of coolant can be used in a wide variety of applications, even mixing with other coolants as a top-off. 

AMSOIL Antifreeze/Coolants

AMSOIL offers three coolants, all of which offer a unique blend of organic acids. We use di-acid technology, which means both ends of the organic acid are active. This makes them work faster and form stronger bonds for enhanced protection.

Zinc Wear Prevention in Motor Oil

Do Older Engines Need Oil With ZDDP Additives?

What is high-zinc motor oil?

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 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.

For best protection, engine builders and gearheads typically use high-zinc and high-phosphorus motor oil to offer extra protection for flat-tappet cams, lifters and other components during break-in. AMSOIL Break-In Oil, for example, contains 2,200 ppm zinc and 2,000 ppm phosphorus.

Buy AMSOIL Break-in Oil

How do ZDDP additives work?

ZDDP anti-wear additives are heat-activated, meaning they provide wear protection in areas of increased friction.

As temperatures rise and surfaces come closer together, ZDDP decomposes and the resulting chemistry protects critical metal surfaces. When parts move during operation, any sliding or rolling motion takes place on top of or within the ZDDP anti-wear film, which reduces metal-to-metal contact.

Flat Tappet Lifters

This is especially important in engines with flat-tappet camshafts or engines modified to create more horsepower. High-tension valve springs, often used in racing applications, also increase the potential for cam wear and require additional ZDDP.

Flat-tappet cams 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 cam-lobe slides rapidly over the tappet, increasing 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 V-8 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 costlier, roller cams are common in most modern vehicles and can be retrofitted into classic-car and hot-rod engines.

The role of piston rings

Even though Hugh didn’t ask about it specifically, I should also mention the importance of seating the piston rings during break-in.

Although a new or freshly honed cylinder appears smooth to the naked eye, it actually contains microscopic peaks and valleys. If the valleys are too deep, they collect excess oil, which burns during combustion and leads to oil consumption.

The sharp peaks, meanwhile, provide insufficient area to allow the rings to seat tightly. That means highly pressurized combustion gases can blow past the rings and into the crankcase, reducing horsepower and contaminating the oil.

Breaking in the engine wears the cylinder-wall asperities, providing increased surface area for the rings to seat tightly. The result is maximum compression (i.e. power) and minimum oil consumption.

Do you always need an oil with ZDDP additives?

Do you need to use high-zinc motor oil in an older engine after break-in, which is typically about 500 miles?

Yes, if you want to maintain horsepower and promote longevity. 

Even after the cam has seasoned, it’s still exposed to tremendous heat and pressure, especially in a heavily modified or racing engine. The constant barrage of pressure can rupture the oil film responsible for preventing wear, leading to metal-to-metal contact.

After break-in, we recommend using an oil with at least 1,000 ppm ZDDP in a flat-tappet engine. That way, you’re providing your expensive engine with maximum protection against wear and horsepower loss.

AMSOIL Z-Rod Synthetic Motor Oil, our primary recommendation for classic cars and hot rods, contains more than 1,400 ppm zinc and more than 1,300 ppm phosphorus.

AMSOIL Signature Series

Signature Series: Maintains Protective Viscosity

The main bearings in your vehicle rely on an oil film thinner than a sheet of paper. When motor oil loses viscosity due to a process called shear, it can fail to provide the required level of wear protection.

Shear (often called mechanical shear) occurs when one layer of oil moves in the opposite direction of another layer of the same oil. This often occurs between the piston and cylinder wall. These two oil films move in opposite directions under intense heat and pressure.

AMSOIL synthetic motor oil features naturally shear-resistant base oils combined with top-tier viscosity improvers to withstand extreme heat and shearing forces. In fact, Signature Series fights viscosity breakdown better than the competition*, providing superior protection of pistons, cams and bearings.

Signature Series stands up to the potentially devastating effects of viscosity breakdown and provides maximum engine protection.

Understanding European Motor Oil Standards

European Motor Oil Specifications Explained

It’s important to use the right motor oil for your European vehicle, but the sea of specifications can make it a challenge. AMSOIL European Car Formula finds the sweet spot of emission compatibility and complete engine protection for every application.

The European Automobile Manufacturers’ Association (ACEA) establishes lubricant standards for Europe, similar to the American Petroleum Institute (API) in the United States. ACEA recognizes that European engines differ from U.S. engines in both design and operating conditions. European OEMs often maintain their own motor oil performance specifications and play a larger role in their development than their U.S. counterparts. Volkswagen* drivers, for example, must use an oil that meets the requirements of VW’s own performance specs. The same holds for Mercedes*, BMW*, Porsche* and other European vehicles. 

Many European vehicles available in North America today feature gasoline and diesel engines with emissions systems that are highly sensitive to the SAPS content of motor oil. These advanced emissions systems require lower SAPS formulations to properly function for a long period of time. The required formulations match the exacting engine oil specifications of ACEA and European OEMs to ensure they are compatible with current emissions systems while still providing engine protection.

FOR THE ULTIMATE COLD-WEATHER PROTECTION, TRUST AMSOIL 

Some gear lubes fail to meet basic low-temperature requirements.

Mobil 1 75W-140 Gear Oil, for example, failed to meet the requirements of the industry standard*. AMSOIL SEVERE GEAR®, on the other hand, delivers 20% more cold-temperature protection than the standard requires. It delivers better cold-temperature protection than Mobil 1 and Valvoline SynPower.

*Based upon results of samples of Mobil 1 75W-140 and Valvoline SynPower 75W-140 purchased in 2018 and tested in ASTM D2983 by an independent testing facility in May 2018. Samples sent blind to eliminate bias.

Signature Series Keeps Engines Cleaner Than Other Synthetic Motor Oils

AMSOIL Signature Series

In general, the higher an oil’s TBN, the better its ability to neutralize contaminants such as combustion by-products and acidic materials. Higher TBN oils neutralize a greater amount of acidic material, which results in longer oil life and cleaner engines.

TBN levels decrease as the oil remains in service. When the level reaches a point where it can no longer protect against corrosion, the oil must be changed.

The TBN Test

The Total Base Number Test (ASTM D2896) uses a series of chemical reactions to measure the alkaline additives in a motor oil. We recognize the value of formulating motor oils with high TBN, and AMSOIL Signature Series Synthetic Motor Oil features the highest TBN of the oils tested.

AMSOIL Signature Series is fortified with a heavy treatment of detergent additive and it delivers 30% more acid neutralizing power1 than Mobil 1, and 36% more than Royal Purple, helping engines to stay cleaner, longer.

The AMSOIL Advantage

AMSOIL synthetic lubricants feature a large dose of quality additives that consistently deliver high TBN for the life of the oil. They neutralize acidic contaminants and keep them in suspension to maximize engine protection. AMSOIL lubricants use detergent and dispersant additives to significantly reduce sludge and carbon deposit formation. In the Total Base Number Test (ASTM D2896), AMSOIL Signature Series 5W-30 Synthetic Motor Oil demonstrated the highest TBN of the oils featured in the test, helping it deliver reliable protection for extended drain intervals.

AMSOIL SABER® PROFESSIONAL

AMSOIL Saber® Professional Proves Itself In Stihl® String Trimmers

Professional-use string trimmers, mowers, backpack blowers and other equipment can run continuously in hot, wet and dirty conditions for months straight. In these conditions, equipment can wear out seasonally, representing the perfect environment for putting AMSOIL products to the test.

Get the SABER’s edge

Before the 2016 summer landscaping season, we purchased three new STIHL FS56RC string trimmers and gave them to Duluth Lawn Care, based in Duluth, Minn. The company relies on a fleet of professional-use mowers, string trimmers and other equipment to provide fast, high-quality lawn-mowing and other services to its 4,500 clients. Historically, the company accumulates about 600 hours per season on each of its string trimmers prior to replacement.

Typical use included continuous daily operation in high heat; wet, humid conditions; exposure to airborne dirt and other contaminants and the general daily abuse of professional-use equipment. 

Each trimmer accumulated approximately 600 hours – far more time than the average homeowner puts on a trimmer. After the season, we disassembled the trimmers and checked for wear, carbon buildup and other distress. Select results are shown here.

After a full season of severe-service at mixed 100:1, AMSOIL SABER Professional...

• Prevented piston-ring sticking for maximum power
• Eliminated carbon deposits in the exhaust port for optimum airflow and power
• Fought engine wear for reliable operation
• Reduced oil costs 65%

SABER fights carbon

Heavy carbon build up can be a problem in professional-use equipment. Oils with poor detergency allow carbon to form in the piston ring lands, on the piston crown, in the exhaust port and on the spark arrestor screen. Carbon chokes off airflow through the engine, robbing the engine of power. It also causes the piston rings to stick in their grooves and fail to form a tight seal against the cylinder wall. The engine loses compression, leading to power loss. This adds up to frustrated workers in the field who can’t work as quickly or efficiently as they need to complete jobs on time and up to standards.

As the images show, SABER Professional nearly eliminated carbon deposits to keep Duluth Lawn Care’s STIHL trimmers running strong all season.

Cuts oil costs

Duluth Lawn Care also saved money on total oil cost. Mixing SABER Professional at 100:1 saved them 65% compared to the cost they would have paid had they used the original equipment manufacturer oil at the conventional 50:1 mix ratio.

Given SABER’s excellent performance, we reassembled the trimmers and returned them to Duluth Lawn Care, allowing the company to use its trimmers longer than historically possible with other oils.

AMSOIL Signature Series and Turbochargers

AMSOIL Signature Series Protects Turbochargers

The turbocharger/direct fuel injection combo has emerged as automakers’ favored choice for producing powerful engines and meeting government fuel-economy requirements. The increased airflow turbos generate enables an engine to burn more fuel and produce more power, but this power comes at a cost. The tremendous heat and stress turbos create cause some oils to break down and form harmful bearing deposits through a process known as turbo coking. Over time, turbos can suffer reduced performance or fail altogether.

How Turbos Could Slow You Down

The deposits common to turbochargers can lead to:

• Blocked oil passages, oil starvation and eventual failure
• Reduced turbine speed – resulting in lower boost pressures, reduced performance and poor efficiency
• Oil breakdown and oil burning
• Expensive turbo rebuild or replacement 

The GM Turbo Coking Test

The Turbo Coking Test was designed to simulate the extreme operating conditions of a turbocharged engine. It evaluates a motor oil’s ability to resist deposit buildup in the oil passages and bushings of a turbocharger. Temperature increases within the turbo and the weight of any deposits are recorded.   

Test Parameters

Engine   -  2012 GM 1.4L

Duration   -  2,000 cycles of extreme heat soaks – approximately 537 hours

Measures   -  A motor oil’s ability to resist deposits in a turbocharger’s oil passages and bushings

Simulates   -   High-heat operation of a turbocharged engine 

Requirement   -  Temperature change within the turbocharger limited to 13 percent

Signature Series protects turbochargers 72% better than required by GM dexos1® Gen 21

The GM Turbo Coking Test requires an oil to limit the temperature change within the turbocharger to 13 percent or less to pass the test. Signature Series limited the temperature increase to only 3.6 percent, controlling heat and proving it protects against deposits common to high-temperature engine environments.

AMSOIL Synthetic Diesel Oil

AMSOIL Synthetic Diesel Oil Greatly Outperforms Minimum Standards

AMSOIL Diesel Oil Offers Best Protection

Shell* recently announced that a sample of “Mobil Delvac 1300* Super 15W-40 did not meet the passing limits for either API CK-4 performance standards, nor the more stringent requirements for Volvo*, MACK* and Cummins*.” The 360-hour Volvo T-13 test measures both oxidation and Kinematic Viscosity, indicating an oil’s ability to resist thermal and chemical breakdown and maintain its protective viscosity in the severe operating environments experienced by diesel engines. Oxidation resistance is critical in order to protect against oil thickening and deposit formation and extend engine life.

AMSOIL has earned the trust of diesel enthusiasts and people who depend on diesel power to make a living. We engineer our synthetic diesel oils to exceed minimum standards and outperform the competition. In independent laboratory testing, AMSOIL Signature Series Max-Duty Synthetic Diesel Oil passed the Volvo T-13 oil oxidation test with flying colors (see graphs below), and it provides 6X more engine protection1, keeping hard-working diesel engines on the road and on the job.

AMSOIL Signature Series Battles Sludge

AMSOIL Signature Series Battles Engine Sludge

Synthetic motoroil

The health of your engine depends on motor oil circulating quickly and efficiently through the system, but sticking components and obstructed passages inhibit motor oil from lubricating, cooling and protecting your engine. Engine “sludge” occurs when oxidized oil and contaminants build up on engine surfaces. It can restrict the flow of oil to the point of engine failure and costly repairs.

Sludge: Where It Starts & How It Ends

The valve cover and oil pan are generally the first areas sludge appears.
The oil pick-up tube screen is often the next spot it accumulates, impeding oil flow through the system.
What begins as a thin film of lacquer or varnish deposits eventually bakes into an expensive mess.

The Sequence VG Engine Test

Engine failures due to sludge are often caused by a clogged pick-up tube screen – the motor is effectively starved of oil. The Sequence VG Engine Test determines how well an oil resists sludge formation and keeps the lubricant flowing freely throughout the system. The test is required for API SN PLUS – a specification recommended by most domestic vehicle manufacturers.

TEST PARAMETERS

Engine

Ford* 4.6L V-8 

Duration

216 hours

Measures

Sludge and varnish deposits, piston ring sticking, clogged oil pump screens and roller pin wear

Simulates

Taxi, delivery or commuter vehicle service

Requirement

Oil pick-up tube screen limited to 10 percent blockage

The Results

Signature Series Synthetic Motor Oil was subjected to the Sequence VG to measure its ability to prevent sludge. As expected, Signature Series produced an oil pick-up tube screen virtually free from sludge (see image). Our unique combination of detergents and high-quality base oils control oxidation and sludge to keep engines clean and efficient. 

Signature Series has 50 percent more detergents1 to help keep oil passages clean and promote oil circulation. It provides 90% better protection against sludge2.

New SEVERE GEAR® Easy-Pack

AMSOIL SEVERE GEAR® Easy-Pack

AMSOIL Easy Packs

Enthusiasts pride themselves on finding their own solutions to tough problems. When there’s no manual, they roll up their sleeves and make it work. But even the most inventive gearhead inevitably throws down an oily rag and wonders why the process has to be so difficult. Changing gear lube is often one of those frustrating tasks.

Differentials Require Service

A clean, high-quality gear lube helps prevent the howls and whines that can occur from extended periods of metal-to-metal contact. It provides differentials and transmissions with crucial protection – particularly against the rigors of towing and hauling – and it should be changed on a schedule to protect your pickup. Unfortunately, changing this vital fluid doesn’t come without challenges.      

Tight Squeeze

Removing the cover on your “pumpkin” and draining the fluid might not be difficult, but installing new fluid requires the ability to push liquid uphill. Unless the pickup is lifted, differentials are packed in high and tight. Reaching fill holes is difficult, and you cannot tip the bottles at an angle that allows the fluid to run into the differential with the help of gravity.

Troublesome Current Solutions

That’s why most gear lube is sold in conical plastic bottles. The idea is that you’ll be able to squeeze the gear lube from the bottle and force it into your diff. Unfortunately, those bottles are rigid and hard to squeeze. You cannot get all of the fluid out of the bottle, so you end up buying more than you truly need to get the job done. Pumps are an improvement, but even those can be leaky or require a third hand to operate without major spillage.

The Mess

No matter your method (pump or conical bottle), it seems impossible to service differentials without making a big mess.

The AMSOIL Solution

The new AMSOIL easy-pack eliminates all of the old obstacles.

Easily access hard-to-reach fill holes. The packaging is flexible. Just bend it until the nozzle is pointing where you need it to be and insert it into the fill hole.

Easily squeeze out entire contents. Empty the easy-pack into your differential with no waste and no mess.

AMSOIL OE 0W-16 Synthetic Motor Oil

Provides Advanced Wear Protection

A 0W-16 viscosity motor oil may seem exotic to North American drivers, but as fuel efficiency requirements increase, it may become a common recommendation of manufacturers worldwide. Japanese engineers have long experimented with ultra-thin motor oils, and 0W-16 has been in regular use in Japan since the 90s.

The Benefits of Going Thin

Lower viscosity motor oil can increase fuel economy, and the pressure to create engines that sip less fuel has hastened the introduction of these viscosities to North America. The stated fuel mileage estimates for several 2018 vehicles were calculated with 0W-16 motor oil installed. Beyond fuel economy, lower viscosity oil can also provide excellent cold-starts in the most frigid temperatures.

OE 0W-16 Synthetic Motor Oil

The primary concern with low viscosity oil is wear protection. Like the rest of the OE line, OE 0W-16 develops a strong fluid film that keeps metal components separated and protected. Our work didn’t end with simply blending a new viscosity. OE 0W-16 Synthetic Motor Oil (OES) is formulated with unique anti-wear additives that protect critical engine parts like pistons and cams. This added protection is particularly important in the extreme environments produced by today’s smaller-displacement engines that run on lower viscosity oil.

• Provides advanced wear protection
• Improves fuel economy & maintains low emissions
• Protects pistons from low-speed pre-ignition
• Keeps engines clean
• Protects in all temperatures
• Meets the requirements of popular new vehicles like the 2018 Toyota* Camry* and the 2018 Honda* Fit*

Recommended for use in applications that require the API SN PLUS (Resource Conserving) specification. Use only where 0W-16 is specified. Do not substitute for 0W-20 or other viscosity.

Why No API Starburst?

The International Lubricants Standardization and Approval Committee (ILSAC) has not recognized the 0W-16 viscosity for the current GF-5 oil category, which is required to display the startburst. It will likely be included in the new GF-6 category expected in 2019 or 2020. As the API “donut” indicates on the back label, OE 0W-16 is licensed for API SN Plus (Resource Conserving).

MPHD still provides some lubricating properties, but its primary focus is corrosion protection. We know many customers use MPHD as a chain lube. We recommend converting to AMSOIL Chain Lube.

Applications

Automotive and trailer undercoat, spare tire carriers, battery terminals, tailgate hinges, handheld tools, snow plows, mower decks and blades, snowblowers, skid-steer attachments, farm machinery, fork lifts, metal gates/fences and much more.

Price Adjustment

With the improved performance of the formula, pricing has increased. Even with the price adjustment, both wholesale and suggested retail prices are very competitive in the corrosion inhibitor market.

We tested MPHD’s corrosion-prevention properties on both aluminum and steel. The three aluminum pieces in the upper left were treated with MPHD on their lower halves, while the three aluminum pieces in the upper right were untreated. The three steel pieces in the lower left were treated with MPHD on their lower halves, while the three steel pieces in the lower right were untreated. Following treatment, the pieces were placed in a 5 percent saltwater bath for one hour, removed and allowed to dry for 23 hours. This process was repeated for two weeks. As seen in the pictures, the portions treated with MPHD show no signs of corrosion.

Metal treated with MP HD remained corrosion free

AMSOIL Firearm Cleaner and Lubricant

Protection and Dependability for Generations

New AMSOIL firearm products provide outstanding benefits for gun owners.

Nearly one in three Americans owns a firearm, typically falling into at least one of three categories. Hunters typically own shotguns to hunt waterfowl or upland birds and/or rifles to hunt larger game. Target/Sport Shooters own all types of firearms (shotguns, rifles, handguns) for recreational shooting. Firearms Professionals (gunsmiths, firearm safety instructors) work with all types of firearms in their professions.

The moving parts on firearms (actions, bolts, hinges) must be cleaned and lubricated to ensure top performance and long life. Hunters and shooters need their guns to perform when called upon, sometimes after an extended period of storage, after sitting for hours in a wet duck blind or while on a remote hunting trip with few opportunities to clean their gun daily.

Since nothing will ruin a hunting trip or day at the range quicker than a malfunctioning firearm, we tested AMSOIL firearm products in a variety of handguns and long guns. The information we gathered, along with extensive testing in our chemical lab, resulted in products dialed in for outstanding firearm protection in the most demanding conditions. As seen in the image, AMSOIL Synthetic Firearm Lubricant and Protectant guards against damaging corrosion better than a leading competitor’s product, helping keep firearms working properly for generations.

New Diesel API Specifications for 2017

Changes in the Diesel Market

Diesel engine technology must deliver reduced emissions and improved fuel economy without sacrificing power.

Federal regulations are dictating that medium- and heavy-duty diesel vehicles must reduce fuel consumption and greenhouse gas emissions 15 percent by model year 2018, driving major changes in the diesel world. The API CJ-4 specification that has represented the standard for diesel oil performance for the past decade will soon give way to new specifications that will evolve with diesel technology to help ensure manufacturers meet federal mandates.

Two Specifications Replace CJ-4

Initially labeled Proposed Category 11 (PC-11) in its working stages, the new API specification has been split in two (API CK-4, FA-4) to accommodate the different requirements of older and newer engines. Both specs focus on drastically reducing emissions and improving fuel economy, while providing increased engine-protection benefits through improvements in oxidation stability, shear stability and resistance to aeration. Engine oils meeting the new specs will begin launching Dec. 1, 2016.

What are the Differences Between API CK-4 and API FA-4?

API CK-4

Designed for current model-year and older diesel engines, API CK-4 oils will offer greater protection and performance benefits over API CJ-4 oils. CK-4 oils will be backward-compatible with CJ-4 oils and will be recommended in all applications specifying CJ-4 (and prior) specifications. In addition to the traditional 15W-40 viscosity grade, CK-4 will offer lower-viscosity options to enhance fuel economy benefits, including 10W-30, 5W-40 and 5W-30.

• Designed for current model-year and older diesel engines

• Backward-compatible with API CJ-4 (and prior) oils

• Offers traditional viscosity grades of 15W-40, 10W-30, 5W-40 and 5W-30

API FA-4

Introduced for 2017 and newer diesel engines designed to meet new emissions standards, API FA-4 is a new category of lower-viscosity oils. It was created to further improve fuel economy and reduce emissions, while delivering the same enhanced protection and performance benefits of CK-4.

API FA-4 oils will be formulated to further improve fuel economy in two ways: lower viscosity and reduced high-temperature/high-shear viscosity (HTHS). While the diesel lubricant market has traditionally been dominated by 15W-40 oils, FA-4 will primarily feature 10W-30 oils. In addition, because lower HTHS numbers are linked with improved fuel economy, the minimum HTHS for FA-4 is lower (2.9) than the minimum HTHS for CK-4 (3.5).

• Designed for certain 2017 and newer diesel engines

• Not backward-compatible

• Designed to improve fuel economy and reduce emissions

• Primarily features 10W-30 viscosity grade

AMSOIL Prepared for Change

AMSOIL customers can be well-assured that we will be ready for the implementation of the new diesel specifications with top-performing synthetic formulations.

New Test Requirements

In order to meet federal regulations, original equipment manufacturers (OEMs) are relying on engine designs that produce ever-increasing operating temperatures. The new API CK-4 and FA-4 specifications introduce new shear-stability requirements to minimize viscosity loss, as well as two new and updated tests to ensure additional protection benefits in the areas of oxidative stability and aeration resistance:

New Mack T13 Test

Measures oil oxidation under the higher temperatures common with modern engines.

New CAT Aeration Test

Replaces the Engine Oil Aeration Test (EOAT), which used hardware that isn’t available anymore
The rest of the tests carry over from API CJ-4.

AMSOIL 5W-30 Signature Series Synthetic Motor Oil

Leading the Field in Deposit Protection

Testing proves AMSOIL Signature Series 5W-30 Synthetic Motor Oil provides more complete protection against damaging deposits than its competitors.

The push toward smaller, fuel-efficient yet powerful engines has driven the development of several key technologies. Gasoline direct injection (GDI) and turbochargers are now common features of passenger cars and light trucks. By 2020, industry experts predict that nearly every new vehicle will feature GDI technology, and the vast majority will be turbocharged. While these advanced technologies enhance performance, they also present serious challenges to motor oil.

The Turbocharger Trade-Off

Turbochargers push more air into the engine’s combustion chamber, providing better fuel-economy and performance but also creating intense engine temperatures. They often operate above 150,000 rpm on exhaust gases exceeding 1000°F. These extreme conditions cause some motor oils to break down and solidify into harmful deposits.

Vehicle manufacturers have long recommended different service intervals based on “normal” or “severe” driving conditions. Turbocharged vehicles are automatically included in the severe service category due to the extreme heat they generate. Motor oil with unique properties is required to combat the effects of intense temperatures.

Proof of Protection

AMSOIL Signature Series 5W-30 Synthetic Motor Oil was tested against two competing brands to determine its level of protection against deposit formation in high-heat applications.

The TEOST 33C test (ASTM D6335) is an industry-standard bench test that simulates turbocharger operating conditions. According to the American Society for Testing and Materials (ASTM), it is “designed to predict the high temperature deposit forming tendencies of an engine oil.” To meet the API SN Resource Conserving and ILSAC GF-5 motor oil specifications that are often recommended by vehicle manufacturers, a 5W-30 motor oil must limit total deposit formation to 30 mg or less.

AMSOIL Signature Series 5W-30 Synthetic Motor Oil held the total weight of deposits to 7 mg, well under the 30 mg limit required by the API and ILSAC, while Royal Purple® API 5W-30 and Mobil1® Extended Performance 5W-30 came in just under the limit at 25.4 mg and 28.2 mg respectively. Signature Series 5W-30 Synthetic Motor Oil protects against harmful deposits on turbochargers 4X better than Mobil1® Extended Performance and 3.6X better than Royal Purple® in industry-standard testing*.

*Based on independent, third-party testing of AMSOIL® Signature Series 5W-30, Mobil1® Extended Performance 5W-30 and Royal Purple® API 5W-30 in the ASTM D6335 bench test required by the API SN Resource Conserving specification.

Test results represent the formulations available as of April 2016. Formulations were coded to eliminate bias during testing and samples were tested in random order. An appropriate number of trials of each oil were run to produce results at or above the 95 percent confidence level when compared to AMSOIL Signature Series 5W-30 Synthetic Motor Oil.
