The difference in performance starts at the molecular level. The refining process used to produce conventional base oils separates crude-oil molecules by weight, leaving molecules of different sizes and shapes. Conventional oils’ inconsistent molecular structure requires more energy to circulate throughout your engine, reducing fuel economy. Unstable molecules in conventional base oils can also evaporate more readily in the presence of extreme heat, causing your oil level to drop. 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 synthetic base oils used to formulate AMSOIL synthetic lubricants, on the other hand, are manufactured using a process that produces base oils of a uniform molecular structure. The smooth, pure molecules in AMSOIL synthetic lubricants slip easily over one another, increasing lubricity compared to conventional oils and maximizing fuel economy. They are also inherently more stable in the presence of heat, resulting in less oil consumption.
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)
