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,

e- Average of the 13 major brands of API SN ILSAC GF-5 tested in September 2011.

 

  
Gilco Premium HD 30
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 an SAE 30.
