Martini Zinc Force 20w50 is a race-inspired high-zinc engine oil engineered for hard-driven classics, muscle cars, and vintage performance machines.

Developed for motorsport and high-load use, Zinc Force features 2000ppm of zinc and a robust 20w50 viscosity to deliver unbeatable wear protection for flat tappet cams, pushrods, and older performance engine builds. The thick oil film holds strong under heat and pressure, making it ideal for track day warriors, burnout cars, or weekend cruisers running high compression or rev-happy setups.

Designed to fight sludge, oxidation, and valvetrain wear, Zinc Force keeps your engine clean and responsive lap after lap.

Not recommended for use with catalytic converter-equipped engines.
