|Cenex AUTO GOLD 5W-30, API SN|
The American Petroleum Institute sets forth a number of laboratory and engine tests required to meet their performance specification. Although laboratory tests alone cannot be used to establish if an engine oil meets API specifications they can be used to determine if it doesn't.
The viscometrics meet the required targets for a 5W-30.
