b- Standards, shown in yellow are established by API, SAE and others. Ranges, shown in teal, represent the high and low data for the 13 major brands of API SN ILSAC GF-5 tested in September 2011.

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,

G-Oil SAE 5W-30 Green Bio-Based Full Synthetic
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.

The following is a comparison of the test results for the sample of G-Oil tested with the API SM requirements.

 
Viscometrics

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