Cam2 SuperPro PLUS 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 Cam2 SuperPro PLUS 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 Cam2 SuperPro PLUS 5W-30 are illustrated by the horizontal line.

The viscometrics of Cam2 SuperPro PLUS 5W-30 meets the required targets for a 5W-30 API SM (SAE J300 specification).

Volatility Phosphorus
The volatility of Cam2 SuperPro PLUS 5W-30 is within the parameters required for an API SM GF-4 designation.


The phosphorus content of Cam2 SuperPro PLUS 5W-30 is within the parameters required for an API SM GF-4 designation.
