What makes high-zinc engine oil special?
High-zinc motor oil is designed for high-performance engines and vehicles with flat-tappet cams, to better protect and deliver performance across all vehicles. This motor oil formulation will have a higher-than-average concentration of Zinc Diakyl Dithiophosphate, an additive that forms a protective, load-bearing film on your internal engine parts. This anti-wear agent prevents metal-to-metal contact, which is common in these high-performance, high-stress engines.
The AMSOIL Difference
Amsoil has developed one of the best formulations for high-zinc motor oil on the planet, and we have tested these motor oils on almost every car and truck on the road in Toledo, Ohio. Our Z-Rod formula is engineered for classic vehicles and hot rods and is designed to better protect flat-tappet cams, lifters, and rockers that are common in older engines. This wear protection will ensure your engine performs better and reduces the risk of internal engine issues, while still giving you the horsepower you need to get the engine truly humming. In comparison, our Premium Protection motor oil blend guards against wear and helps clean your engine of deposits that can lead to rust buildup and reduced performance. This specific formulation is perfect for air and liquid-cooled engines.

Frequently Asked Questions
No Dumb Questions, Just Dry Dipsticks
What kinds of cars take high-zinc motor oil?
In general, high zinc motor oil is designed for classic cars and muscle cars from the 1990s or earlier. Additionally, if you have a flat-tappet camshaft engine or a racing or high-performance engine, your vehicle will benefit from the protection provided by high-zinc engine oil. There are other use cases, such as break-in applications for new or rebuilt engines, that are also well-suited to high-zinc motor oil.
Why would you use high-zinc motor oil instead of conventional motor oil?
If you are running an older classic car or muscle car, using a high-zinc motor oil is a great way to provide added protection for your engine, especially if your vehicle has a flat-tappet camshaft. Unlike conventional motor oil, the high zinc motor oil formulation will provide your engine with the anti-wear protection that you need in these high-pressure and high-performance engines to prevent wear from metal-on-metal grinding that can happen.
Can I use high-zinc motor oils in diesel engines?
Yes, our Premium Protection high-zinc motor oil can be used in air-cooled and liquid-cooled gas and diesel engines. If you have any questions about whether your specific vehicle can use high-zinc motor oil, please reach out to a Northwest Ohio Independent Amsoil dealer who can help you find the perfect motor oil for your needs.
