Torco ZEP: Fortify Your Engine with MPZ®
Restore critical anti-wear protection to your motor oil for maximum performance and longevity, especially in high-stress applications.
The Torco ZEP Advantage
Torco ZEP features **MPZ®**, a proprietary additive technology providing an unrivaled balance of Zinc, Phosphorus, and Molybdenum. This friction-fighting chemistry reintroduces a robust anti-wear package into modern oils, offering superior protection where it's needed most.
Eliminates 'Dry Start' Damage
ZEP's polar-attraction formula coats all metal surfaces, providing critical lubrication during engine startup—the leading cause of wear in stored or infrequently driven vehicles.
Unmatched Film Strength
The protective layer created by ZEP won't rub off, wear off, scrape off, or scuff off under extreme pressure. It is the ideal solution for high-performance engines, especially those with flat tappet cams.

Ideal Applications
Engineered for engines that demand superior anti-wear defense.
Racing & High-Performance Engines
