Older engines cannot be adequately protected by synthetic oil. High zinc-based motor oils are therefore used in older engines. Zinc compounds in zinc oils help to reduce friction in engine components. These oils are ideal for older engines that need better lubrication or protection from oil engine components. High zinc oil is used in racing oil due to its outstanding performance and resistance against wear and tear.
Many brands offer high zinc-based motor oil. This article will focus on some well-known brands and their features.

FAQ’s on High Zinc Motor Oil Brands
Why should you use High zinc motor oil?
High zinc motor oil is typically used in vehicles that require extra care. It provides better resistance to wear and tear and friction at high temperatures. These are usually recommended in high-performance racing vehicles or older cars. Using high zinc motor oil also eliminates emissions from your engine, making it more environmentally friendly.
What to Consider When Choosing Racing Oil with Zinc?
You should consider high zinc motor oil based on your performance requirements, vehicle viscosity, and budget. You should also consider extra additives and oil compatibility with your engine.
What Engines Need Zinc?
If you have a v6 or v8 engine built before 1988, you will certainly want high zinc motor oil. This is because flat tappets designed camshafts were common in cars manufactured around 1980. The addition of zinc to your flat tappet camshaft allows the tappets to get the best out of cam lobes, resulting in critical initial firing and break-in inside racing and muscle cars. Zinc additives also increase the life of cam lobes.
Can You Put Too Much Zinc in Oil?
It is recommended that you get high zinc motor oil directly from the market because the oil has a fixed ratio of zinc and phosphorus. Adding more ZDDP additives to your oil might be dangerous because it can cause acid formation in the oil, which can lead to the abrasive wearing of engine components. The amount of zinc in your oil depends entirely on your oil brand and your engine configurations. However, zinc concentrations ranging from 1000 ppm to 1400 ppm are more than adequate for old engines.
It is important to protect your engine and give it extra care. For older engines and high-performance race cars, it is a good idea to use high-zinc motor oils. Your mechanic should always advise you on how to use high-zinc motor oil in an engine. You should choose the right oil for your vehicle, taking into account your budget and viscosity requirements.
