Which Oil is right for you?

The current and previous API Service Categories are listed below. Vehicle owners should refer to their owners manuals before consulting these charts. Oils may have more than one performance level.

For automotive gasoline engines, the latest engine oil service category includes the performance proerties of each earlier category. If an automotive owners manual calls for an API SJ or SL oil, an API SM oil will provide full protection.

For diesel engines, the latest category usually - but not always – includes the performance properties of an earlier category.
