c-Test Method for metal analysis is ASTM ASTM D5185.

d- Although silicon is used as an antifoam additive in lubricants, concentrations above 7ppm have been linked to contamination from abrasive material,

Valvoline Premium Conventional
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 Valvoline Premium Conventional tested with the API SN ILSAC GF-5 requirements.

 
Viscometrics

The viscometrics meet the required targets for an SAE 5W-30 API (SAE J300 specification).

 

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