This Gulf standard is concerned with measuring the tendency of lubricating oils to deteriorate on oxidation under specified conditions. A measure of the deterioration is obtained by comparison of the viscosity and carbon residue before and after oxidation. The standard is not suitable for additive-type oils (except those containing ashless additives) or those which form solid products or lose more than 10% of their weight by evaporation during the test.
