Why Add Torco ZEP Zinc Engine Protector?

As environmental regulations become increasingly strict, the zinc (ZDDP) content in modern engine oils has been gradually reduced to protect catalytic converters. However, for high-performance engines, classic cars, or engines using flat tappet camshafts, zinc remains an essential anti-wear component.

Torco ZEP (Zinc Engine Protector) was developed precisely to address this need.

Torco ZEP is a professional zinc engine oil additive from Torco International (USA). Without altering the original characteristics of the engine oil, it effectively supplements zinc and phosphorus, forming a high-strength protective film on metal surfaces to significantly reduce friction and wear.

What Changes Can You Expect After Adding Torco ZEP?

First, enhanced engine protection.
During cold starts or high-load operation, ZEP helps reduce metal-to-metal contact, providing especially strong protection for high-wear components such as camshafts and rocker arms.

Second, smoother operation and reduced noise.
With lower friction, the engine runs more smoothly and quietly, offering a more refined driving feel—particularly noticeable in older or high-mileage engines.

Third, improved stability under high temperatures and high RPM.
For aggressive driving, track use, or high-performance tuned vehicles, Torco ZEP delivers greater lubrication stability and peace of mind, helping extend engine life.

Suitable Applications

• Classic cars and vintage vehicles

• Engines with flat tappet camshafts

• High-performance or modified vehicles

• Vehicles that are driven infrequently or stored for long periods

Torco ZEP Zinc Engine Protector is not designed to deliver short-term performance gains. Instead, it focuses on what matters most—core engine protection.
If engine durability, classic car maintenance, or reliability under high-load conditions is your priority, Torco ZEP is a solution you can trust.
