Advanced AutoParts 5W-30
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 Advanced AutoParts 5W-30 as compared to the API SM requirements.

The API limits for each test are shown by the yellow bars. The test result for Advanced AutoParts 5W-30 are illustrated by the horizontal line.

The viscometrics of Advanced AutoParts 5W-30 meets the required targets for a 5W-30 API SM (SAE J300 specification).

Volatility Phosphorus
The volatility of Advanced AutoParts 5W-30 is within the parameters required for an API SM GF-4 designation.



Although the phosphorus content in Advanced AutoParts 5W-30 exceeds the parameters required for an API SM GF-4 designation, it falls within the expanded range used by API in its EOLCS Aftermarket Audit Program (AMPA). The expanded range allows for 540 to 880ppm.
