Warren Motor Oil 10W-30 Motor Oil
The American Petroleum Institute sets forth a number of laboratory and engine tests required to meet an API SM performance specification. Although laboratory tests alone cannot be used to establish if an engine oil meets API SM, they can be used to determine if it doesn't.

What follows is a comparison of the test results for Warren Motor Oil Motor Oil 10W-30 as compared to the API SM ILSAC GF-4 requirements.

The API SM and ILSAC GF-4 limits for each test are shown by the yellow bars. The test result for Warren Motor Oil 10W-30 are illustrated by the horizontal line.

 
Viscometrics
The viscometrics of Warren Motor Oil 10W-30 meets the required targets for a 10W-30 API SM (SAE J300 specification).

   
Volatility Phosphorus
The volatility of Warren Motor Oil 10W-30 is within the parameters required to meet an API SM GF-4 Service Category.

 

The phosphorus content in Warren Motor Oil 10W-30 is within the parameters required to meet an API SM GF-4 Service Category.
