Devoted to Protection

 

Keep the car you love safe with 75% more engine protection against horsepower loss and wear than required by a leading industry standard*

* As required by a leading industry standard. Based on independent testing of AMSOIL Signature Series 5W-30, in ASTM D7320 as required by API SN specification.

The Proof

The American Petroleum Institute sets the minimum standards oil must pass to ensure it will provide adequate protection. One of these standards, the Sequence IIIG Test, subjects oil to 100 hours of use at 302°F- 100° higher than normal operating temperatures- and measures its ability to prevent wear, deposits and more.
