Classic Mini Oil Motor oil 20w50 Millers Oils

Description

Classic Mini Oil 20W50 is a high-quality multigrade mineral motor oil specially developed for classic Mini motorcycles where the engine and gearbox share the same oil. The oil contains carefully selected base oils and specific gearbox additives that both lubricate the engine and ensure smooth and precise gear shifting.

This unique formulation makes the product particularly suitable for the original classic Mini, Cooper, Cooper S and for owners who want the best performance and protection for their A-series engine and integrated gearbox.
