Torco ZEP Zinc Oil Additive

Torco ZEP Zinc Oil Additive: Essential ZDDP Protection for Classic Engines

Is your high-performance or classic engine at risk from modern motor oils? Torco ZEP (Zinc Engine Protector) is a concentrated zinc oil additive designed to restore vital anti-wear chemistry that has been removed from today’s retail oils. Specifically formulated to provide a sacrificial layer of Zinc Dialkyl-Dithiophosphate (ZDDP), Torco ZEP is the "insurance policy" your flat-tappet camshaft and high-load engine components need to survive.

Why Does Your Engine Need a Zinc Additive?

Modern API SM, SN, and SP category motor oils are designed to be "catalytic converter friendly," which means they have significantly lower levels of zinc and phosphorus. While this protects emissions systems, it leaves older and high-performance engines vulnerable to metal-to-metal contact.

• Restores ZDDP Levels: Puts back the high-pressure lubricants that modern oil manufacturers took out.
• Eliminates Dry Start Wear: Torco ZEP creates a persistent coating on all internal engine parts that won't rub, scrape, or scrub off—essential for vehicles that sit in storage.
• Protects Flat-Tappet Cams: Provides the high-film strength required to prevent camshaft lobe failure in vintage and racing engines.
• Extends Engine Life: Reduces friction and heat, ensuring your high-dollar build lasts longer and performs more efficiently.

• Modern Muscle & Race Engines: Provides extra security for high-lift cams and heavy valve spring pressures.
