About this item

  • Creates an anti-wear layer at friction points to prevent metal-to-metal contact and eliminate wear.
  • Engine break-in where the new camshaft and lifters need extra protection, and ZDDP is perfect for that.
  • Mandatory for all flat tappet engines.
  • Works in both synthetic and standard mineral-based oils.
  • Two fluid ounces mixed with 6 quarts of oil create a ratio of 3000 – 3200 parts per million (ppm).
  • ZDDP protects high-load components from excessive wear and failures.
  • Use in every oil change for maximum protection.



Product Description

ZINC (ZDDP) is widely known to be the prime ingredient to protect flat tappet cams and valve train components within engines with high valve spring pressure, to control aggressive camshaft profiles. ZINC is also the protective additive necessary to protect older vintage engines that were produced when Zinc was the primary additive used to provide the last measure of protection against catastrophic failure. The proper amount of ZINC is to be used in relation to engine oil for the ideal amount of protection. Zinc provides the proper amount of the ZDDP additive to treat six quarts of engine oil, giving the proper ratio of 3000-3200 ppm for proper engine break in and protection of high pressure valve train components. Blended with a light base mineral oil that aids in the quick and complete dispersion into any engine oil for fast activation and protection during first startup. For maximum protection ZINC must be reapplied to engine oil when the oil and filter are changed.

How Does ZDDP / ZINC Work in Engine Oil?

As ZINC (ZDDP) is heated it creates a film that coats the engine parts with an anti-wear layer, think of it as a sacrificial layer that will wear away preventing wear on your vital engine parts. This is very beneficial for flat tappet motors, which have as the name suggests a flat lifter. When the engine is running the cam lobe is in constant contact with the flat surface of the tappet. This creates high temperatures due to the friction between the two. If the protective film created by the ZDDP was not present this heat and friction would wear away at the lifters and cam leading to engine failure.

ZDDP is Vital for Engine Break In

Breaking in an engine is vital to ensure proper sealing of the piston rings as well as setting the lifters to a new cam. This process will create a lot of heat and wear as engine parts wear away to fit the small areas that machining and manufacturing are just not able to fit up exactly. With Zinc these areas will be treated with a sacrificial layer preventing more wear than is needed to break the engine in.

I used it with my recent oil change in my Chevelle and it seems to help the flat tappet lifters and I’ve noticed the car accelerates much better

Used it for a ticking noise with my Jeep. Added 1 full bottle for 6 quarts of oil. Within a half hour of driving, ticking went away. Flat tapped heads on my Jeep need Zinc. Impressed. Worth the money.

It will take time to possibly see results, but so far I have seen no damage as a result of the product

Made the engine quieter and gave me about 2 to 3 more mpg, Since the engine takes 10 quates of oil I use 2 bottles when I change the oil. This truck has only ever had Royal Purple oil 15/40 oil since it was new in 2005 and 75000 miles later still going strong.

This is not something that is going to increase mileage or work miracles to extend oil changes by thousands of miles. It is simply an additive to add back luibicating properties to newer synthetic oils that were removed to placate the EPA nazis, no matter the harm to your engine. These materials are especially beneficial in the valve train and piston skirt areas that have a high metal to metal contact.
