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.

Oil Additives Can Offset the Careful Balance of a Well-Formulated Motor Oil

An overabundance of anti-wear agents, for example, can lead to reduced resistance to corrosion.

Dan Peterson - Vice President Technical Development AMSOIL Inc.

I don't get up on my soapbox very often – partly because I have put on a few extra pounds and don't want to break the box, and partly because it's just not my personality. Not a lot of things really get to me, but when I come across something that does, you don't want to be with me in the car for a long drive. One of these things is engine oil additives. The last time I stopped by the local parts store to pick up a tool for a brake job on my Ford Fusion, I stood in the aisle for a full 10 minutes looking at the huge display of engine oil additives. I was not in a hurry, so I picked up a dozen or so and read the marketing claims.

Wow; it seems almost any internal engine problem in the world can be solved simply by using an engine oil additive. "Restores engine life, eliminates dry starts, eliminates engine noise, restores parts' surfaces AND compensates current wear!" Now I see why people buy all these oil additives. Too busy or just not interested in taking care of your vehicle? Just wait until you have a problem and then buy a solution at the local parts store and you are back in business. Our instant-gratification culture pushes us into believing in quick solutions. In reality, there are very few quick solutions that can correct years of neglect in any area of life, including your internal combustion engine. Very few, if any, engine oil additives solve engine issues overnight or somehow restore engines to their original condition. So how do you get the longest, trouble-free life out of your engine? Use a highquality, trusted brand of synthetic motor oil regularly and don't add any engine oil additives. Formulating a motor oil to perform all the critical jobs required by your engine is a balancing act. You can't just focus on improving one property without testing and evaluating the impact on all critical oil properties. Many times, use of additives improves one property, but causes other properties to take a nosedive. 

Formulating synthetic motor oils is a core strength developed over the past 40 years at AMSOIL, and it is not an easy task. Motor oils need to protect engines against abnormal wear, excessive varnish, sludge, rust and corrosion and damaging foam. Motor oils also need to remove heat, help meet fuel economy standards, keep engine seals from leaking and keep catalytic converters working effectively over their projected lives.

Many negative outcomes derived from using engine oil additives have been documented over the years, including accelerated corrosion, excess oil thickening in cold temperatures and increased deposit formation. Most of these negative outcomes are relatively complicated chemical interactions, but just like your family is interconnected, so is the chemistry in your motor oil. When you add Uncle Buck to your family for a week, you and the kids all have a lot more fun staying up late and listening to stories, but he upsets the family balance. The kids have black circles under their eyes from staying up too late, you argue with your spouse about a few choice new words the kids picked up and you have to clean up cigar butts all over the garage when he finally leaves. Seems fun at first, but a week-long visit proves having Uncle Buck live with you for good isn't such a good idea.

The chemicals in motor oils are all interconnected and work together like a family unit to provide all the important properties required to keep your engine operating well. Most motor oils are designed with a measured amount of wear protection and deposit control. The problem comes when you add a whole bunch of extra or new wear protection or deposit control, and it ends up creating corrosion or destroying coldtemperature properties. Motor oils that perform well have some Uncle Buck built in, but at an appropriate level that does not upset critical chemistry in other areas designed to keep your engine running smoothly over the long run.

If you want a more detailed explanation by industry experts, a recent Noria announcement outlined that "Aftermarket oil additives can backfire." In the book, "Practical Handbook of Machinery Lubrication," the following description is listed:

"Increasing the percentage of a certain additive may improve one property of an oil while at the same time degrade another. When the specified concentrations of additives become unbalanced, overall oil quality can be affected. Some additives compete with each other for the same space on a metal surface. If a high concentration of an anti-wear agent is added to the oil, the corrosion inhibitor may become less effective. The result may be an increase in corrosion-related problems."

It's a much fancier way of saying too much of your Uncle Buck is not good for your marriage. Next time you talk to someone who is contemplating using one of those flashy new engine oil additives, tell them about the importance of maintaining the critical balance in motor oil and what can happen when it becomes unbalanced. 

AMSOIL Synthetic Motor Oils 

3,000-Mile Oil Change Comes Under Fire

The standard 3,000-mile oil change interval is under attack. Promoted for years by most motor oil companies and quick lube businesses as an essential part of proper vehicle maintenance, the public has become much more skeptical in recent years. In fact, searches for "3,000 mile oil change" in top Internet search engines such as Google and Yahoo! primarily yield articles and blog postings that challenge the practice and refer to it as a "scam" or "myth."

AMSOIL synthetic motor oil was introduced in 1972 as the only motor oil on the market recommended for 25,000-mile/one year drain intervals, and the company has spent much of the last 36 years as the lone voice promoting the benefits of extended drain intervals. However, AMSOIL has recently welcomed an increasing number of companies and organizations to the party. Although they still don't recommend drain intervals as long as AMSOIL recommendations, the momentum is growing.

Vehicle manufacturers have mostly recommended oil change intervals exceeding 3,000 miles in recent years. In fact, most recommend intervals of 5,000 miles or more. Ford Motor Company recommends drain intervals of 7,500 miles in its model year 2007 and newer vehicles, while other manufacturers incorporate oil monitoring systems in their newer vehicles that allow motorists to extend drain intervals even further.

In its December 2006 issue, Consumer Reports encourages drivers to follow the longer oil change recommendations of vehicle manufacturers, saying, "Although oil companies and quick-lube shops like to promote this idea [that engine oil should be changed every 3,000 miles], it's usually not necessary. Go by the recommended oil-change schedule in your vehicle's owner's manual. Most vehicles driven under normal conditions can go 7,500 miles or more between oil changes. Some models now come with a monitoring system that alerts the driver when the oil needs changing. Depending on driving conditions, these can extend change intervals to 10,000 or 15,000 miles."

Steve Ritter, senior editor of Chemical & Engineering News, writes, "Conventional wisdom has held that the oil should be changed about every 3,000 miles. This notion has been ingrained into people's heads for decades, in part as a marketing ploy by oil companies. The 3,000-mile interval made sense when engines used single-grade nondetergent oils. But with the latest oils and car designs, it's no longer necessary to change oil that often under normal driving conditions."

Concerned about the effects of used oil on the environment and responding to research thatindicates 73 percent of California drivers change motor oil more often than their vehicle's manufacturer recommends, the California Environmental Protection Agency and its Integrated Waste Management Board (CIWMB) have emerged as another strong opponent of the 3,000-mile oil change. The group recently launched a public information program and website (www.3000milemyth.org) designed to "bust the 3,000-mile myth" and encourage drivers to reduce used oil volume by following the longer oil drain recommendations of vehicle manufacturers.

"Used motor oil poses a great risk to the environment," said CIWMB Chair Margo Reid Brown. "With better made cars and the rise of synthetic oils, the 3,000-mile standard is not always recommended."

Most recently, General Motors announced its support of the CIWMB program to educate drivers about oil change intervals. According to GM, standard 3,000- mile oil change recommendations are based on outdated engine and oil technology, and the company instead recommends changing oil based on its Oil Life System. Currently included on over 97 percent of all GM vehicles sold in the U.S., the GM Oil Life System typically allows drivers to extend drain intervals up to 10,000 miles through use of a computer-based software algorhythm that measures vehicle operating conditions. With 31 million vehicles on the road equipped with the Oil Life System, GM spokesman Tom Henderson claims following its recommendations rather than the 3,000-mile rule could save 100 million gallons of oil annually.

In addition to the environmental benefits associated with less waste oil, extended drain intervals save consumers money. For example, customers who purchase conventional oil at $3 or more per quart, drive 12,000 miles per year and follow 3,000-mile oil change recommendations spend atleast $60 per year on oil alone (assuming a five-quart sump capacity). AMSOIL Dealers and AMSOIL Preferred Customers who pay $6.45 per quart (based on case pricing) under the same conditions pay only $32.25 per year.

"When it comes to oil changes, less is more," claims the CIWMB. "You'll have more money in your wallet by changing your oil less, and fewer oil changes mean less oil that needs to be safely managed and recycled."

Premium AMSOIL synthetic motor oils offer the longest drain intervals on the market, unsurpassed protection and performance that effectively extends equipment life and improved fuel economy, saving customers money at the pump and reducing the nation's dependence on foreign oil.
