AMSOIL Motor Oil vs. Conventional Oil

Although you might know that synthetic oils outperform conventional oils, you might not understand why. The differences begin at the molecular level.
Synthetics don’t contain the impurities and molecular irregularities inherent to conventional oils. Synthetics’ pure, uniform molecular structures impart properties that provide wear protection, extreme-temperature performance and fuel efficiency conventional lubricants just can’t touch – all of which helps you save money with vehicles that run better and last longer.


Only a microscopic film of oil separates metal surfaces in your engine from touching and causing wear. AMSOIL synthetic motor oils form a more durable fluid film than conventional oils due to their resilient base oils. They reduce wear and help you maximize engine life.


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.

The tested conventional oil showed 60% more oil consumption* than AMSOIL Signature Series 5W-30, requiring more frequent top-off. Conversely, AMSOIL Motor Oil showed 38 percent less consumption* than the conventional oil.

So if you want the first and best in synthetics, choose AMSOIL!
