Advanced Protection Features
CLASSIC MEDIUM features a standard multigrade cold temperature SAE viscosity grade with an increased operating temperature range that provides an added layer of protection for the engine, especially under increased load and temperature conditions. The multigrade formulation provides better start-up protection and better protection at operating temperature than monograde oils, eliminating the need for seasonal oil changes.
The oil contains a special additive pack that suits vehicles of the era and is compatible with grades that were originally specified. This oil exceeds the specification requirements of original oils required during this period, offering a greater level of engine protection compared to original oils.
