Benefits of Using Synthetic Oil

 How You Can Benefit From Using a Synthetic Oil?

What is synthetic motor oil? AMSOIL synthetic lubricants are chemically engineered to form pure lubricants. They contain no contaminants or molecules that don’t serve a designed purpose. Their versatility and pure, uniform molecular structures impart properties that provide better friction-reduction, optimum fuel efficiency, maximum film strength and extreme-temperature performance conventional lubricants just can’t touch.

Conventional lubricants, on the other hand, are refined from crude oil. Contaminating elements such as sulfur, nitrogen, oxygen and metal components such as nickel or vanadium are inherent to crude oil and cannot be completely removed through the refining process. The oil refining process separates the various types of molecules in the oil by weight, leaving molecules similar in weight but dissimilar in structure, reducing performance.

Maintain a Cleaner Engine

Your oil circulates through your engine helping pick up debris and deposits in order to keep your engine clean. Over time, your oil can become old and thick, causing it to be part of the problem. As conventional oils break down, they can cause sludge formation which can lead to more buildup. Luckily, synthetic oil is made up of a cleaner formula that can resist sludge formation for longer. This means it can keep things cleaner, helping reduce the strain your engine has to endure.

What it Means to Motorists
Modern engines demand increased performance from motor oil. Turbochargers, direct fuel injection, variable valve timing and other advancements improve fuel economy and performance, but result in increased operating temperatures, pressures and contaminants, while increasing the likelihood of viscosity loss due to mechanical shear. Motor oil today must guard against the negative effects of added stress for today’s sensitive engine systems to function as designed.

While not all motor oils may be up to the challenge, these test results prove that Signature Series offers exceptional protection against harmful deposits, viscosity increase and wear in the toughest conditions, helping motorists maximize the performance and longevity of their vehicles. Its ability to keep components clean despite increased stress helps sophisticated engine systems operate smoothly and demonstrate long life. Signature Series’ outstanding performance combined with its extended-drain capabilities offer a unique combination of quality and value not offered by other motor oils.

Better Performance in All Temperatures

Extreme heat and freezing temperatures can both negatively affect conventional oils. Summer highs can cause conventional oils to oxidize and evaporate, leaving your engine exposed to premature wear. During the winter, freezing temperatures can cause conventional oils to become thick and move more sluggishly. Your oil can take a while to get back to its normal consistency, leaving your engine exposed, especially on cold starts. Synthetic oil can hold onto is ability to flow and its viscosity no matter how hot or cold temperatures get. This means you don't have to worry about premature wear caused by unreliable oil.

When the temperature drops, motor oils thicken and move slower, causing parts of your engine to remain unprotected for a short period of time. AMSOIL is more fluid at cold temperatures than the tested conventional oil, giving you 36% easier and faster cold starts*. This means that it can reach vital components faster, providing more immediate engine protection and reduced wear.
*Supported by Cold Crank Simulator test (ASTM D5293) 


In order to keep on pace with the increasingly strict fuel economy standards, vehicle manufacturers are designing engines differently, causing them to run hotter than ever before. The average operating temperature is up to 235°F, and even higher under heavy loads. This heat can quickly break down the oil and cause oxidation, sludge and deposits.

Recent tests show AMSOIL keeps engines 81% cleaner* (5 times cleaner) than conventional oil by better resisting the formation of deposits.
*Supported by TEOST 33C test (ASTM D6335) 

Environmental Conservation

AMSOIL synthetic motor oils are designed to reduce emissions, last longer and reduce fuel consumption – all features that help prevent pollution. They resist volatilization (burn-off) better than conventional oils, which cuts tailpipe emissions, while extended-drain AMSOIL synthetic oils generate less waste oil and packaging waste since motorists use less oil throughout the year.

The commitment of AMSOIL to the environment extends beyond its products to its environmental management system, which is registered to the ISO 14001:2004 standard. AMSOIL closely monitors its environmental impact and has taken numerous steps toward improvement every year. 

AMSOIL has always recognized that doing what’s right for the environment not only makes ecological sense, it also improves business. It’s one of the company’s founding principles and will remain so well into the future.

Save Money

If you don't look forward to getting oil changes, synthetic oil is perfect for you. Since its formula is manmade and carefully crafted, oil changes are needed less often when using a synthetic oil. In the long run, using a synthetic oil can also reduce engine strain, keeping your engine healthier for longer. Another reason you may save money while using a synthetic oil is because it can help you get better gas mileage, helping you save at the pump.

AMSOIL INC. has conducted industry-standard tests to demonstrate. For example, AMSOIL synthetic diesel oil, transmission fluid and gear oil increased fuel economy 6.54 percent in short- to medium-haul diesel applications in one test, while boosting fuel economy in diesel trucks used in stop-and-go city driving conditions 3.15 percent in a second test. The same synthetic technology extends to the entire line of AMSOIL synthetic lubricants, delivering maximum fuel economy in all your vehicles and equipment.

Likewise, a conventional oil showed 60 percent more oil consumption than AMSOIL 5W-30 Signature Series Synthetic Motor Oil in testing, requiring more frequent top-offs. Conversely, Signature Series showed 38 percent less consumption than the conventional oil.*

It all means you save money at the pump and have to top-off your oil less often.

*Supported by the NOACK Volatility Test (ASTM D5800)

The base oils used in conventional oils contain molecules of different sizes and weights as well as unwanted materials, like wax. This typically requires more energy to circulate throughout your engine, which can reduce fuel economy. Conversely, AMSOIL synthetic motor oils are formulated using molecularly uniform synthetic base oils that slip easily over one another and are free of unwanted materials. They help reduce energy lost to friction and maximize fuel economy.


If enough motor oil is consumed, eventually there may not be enough to reach all the complex parts of your engine, which can potentially cause damage.

AMSOIL Signature Series 5W-30 showed 38% less oil consumption* than the tested conventional oil, requiring less-frequent top-offs.

Cold Pour Test: AMSOIL Synthetic Oil versus Conventional Oil

One key measure of lubricant quality is its ability to flow at low temperatures. To demonstrate this, we compared two different 5W-30 motor oils and see how they perform under very cold temperatures.

AMSOIL Warranty

AMSOIL guarantees the performance of its products, so you can be confident they perform as advertised. AMSOIL introduced the world’s first API-qualified synthetic motor oil and has since introduced a full line of industry firsts. For more than 40 years, AMSOIL synthetic lubricants have proven themselves in the lab, on the racetrack and on the highway.

"I've always run AMSOIL fluids since the day I bought it, AMSOIL is a proven product.”

Ray McClelland 
AMSOIL Products Front to Back for Trouble-Free Extended Engine Life

“I have been using AMSOIL motor oils and filters since 2001. I was amazed to see the diesel oil was still clean with 36,000 miles on the oil change. Usually my engine oil would be black again right after a fresh oil change.”

Steven Brick 
Lavon Miller Turns Passion into Successful Business and Championships

“With AMSOIL products, we run the Severe Gear® Gear Oil in the front and rear differentials. We run the Transmission Fluid in the transmission. In comparison to just running some of the standard fluids, we see better heat distribution in the bearings and in the steels on an extreme application. And also the oil analysis has looked really good coming back from the engine in running the AMSOIL products.”
