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.

1 Based on independent testing of AMSOIL Signature Series 0W-20 in ASTM D6891 as required by the API SN PLUS specification.

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.

2 Based on independent testing of AMSOIL Signature Series 5W-30 motor oil, in the LSPI engine test as required for the GM dexos1® Gen 2 specification.

Signature Series Limits Oil Consumption

Signature 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.
