Mobil Super 5000
The American Petroleum Institute sets forth a number of laboratory and engine tests required to meet an API SN ILSAC GF-5  performance specification. Although laboratory tests alone cannot be used to establish if an engine oil meets API SN, they can be used to determine if it doesn't.

The following is a comparison of the test results for the sample of Mobil Super 5000 tested with the API SN ILSAC GF-5 requirements.

 
Viscometrics

The viscometrics of meets the required targets for a 5W-30.

 
   
Volatility Phosphorus
The volatility meets the requirements for an API SN ILSAC GF-5 designation.
