Whereas the results of the tests conducted on this sample meet the requirements for an SAE 5W-30 engine oil, it cannot be determined if it meets API SG/CD since these specifications are obsolete.
Advisory:
This product is labeled as meeting
API SG/CD which is an obsolete specification and is not
recommended for passenger cars built after 1993. In
addition, this product is labeled as meeting API CD which is
also an obsolete specification.

PolyGUARD 5W-30, API SG/CD | ||||
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.

Viscometrics | ||||
The viscometrics meet the required targets for a 5W-30.
