Is AMSOIL Good for Gasoline Vehicles?
Why is AMSOIL good for your engine? It Outperforms Industry Standards
The Sequence IVA Engine Test simulates extended periods of stop-and-go driving - conditions that encourage engine wear. We used Signature Series 0W-20, the lightest viscosity in the line, to further increase the severity of the test. AMSOIL Signature Series Synthetic Motor Oil provided 75 percent more engine protection against horsepower loss and wear1 than required by the industry standard, extending the life of vital components like pistons and cams.
AMSOIL Protects Against LSPI
Occurring in today's advanced engines, low-speed pre-ignition (LSPI) is spontaneous ignition of the fuel/air mixture prior to spark-triggered ignition. Original equipment manufacturers (OEMs) like GM* have addressed the issue by designing tests to determine a motor oil's ability to prevent LSPI. Signature Series Synthetic Motor oil provided 100 percent protection against LSPI2 - zero occurrences were recorded throughout five consecutive tests.

Signature Series Fights Viscosity Breakdown
AMSOIL fights viscosity breakdown better than the competition3, providing superior protection of pistons, cams and bearings.
Signature Series Neutralizes Acids
AMSOIL Signature Series is fortified with a heavy treatment of detergent additive and it delivers 30 percent more acid neutralizing power4 than Mobil 1, and 36 percent more than Royal Purple, helping engines to stay clearner, longer.
Signature Series Limits Oil ConsumptionSignature Series has a uniform structure that limits evaporation and keeps it where it is needed most - protecting your engine. It limits volatility (burn-off) that occurs when oil gets hot, protecting against harmful effects of oil thickening, additive imbalance, higher emissions and oil consumption. Reduces the need for frequent oil top-offs.
Signature Series' well-balanced formula delivers exceptional protecion in all areas of motor oil performance.
