Complete chemical and physical property test results shall be submitted for each grade of oil for which qualification is requested. Single Cylinder Engine tests shall be performed on the lightest and heaviest single SAE grade oils to be blended from the same base stock materials (neutral and bright stock). All single grade oils blended from the same base stock materials and meeting SAE viscosity classification standards between the two tested products will be granted qualification approval based on similarity. No read-across approvals will be granted for multi-grade oils.
The single grade lubricating oils shall be refined petroleum products and may contain pour point depressants up to a maximum amount of 1 .0% by weight as well as an antioxidant in an amount not to exceed 0.5% by weight. In addition to these materials, multi-grade oil may also contain a viscosity index improver. Silicone antifoam additives may be used up to a maximum of 25 ppm. Crude source(s) and the types of processing used in the manufacture of the base stocks shall be identified in accordance with Appendix A.
