REV X ZDDP Oil Additive - Zinc & Phosphorus

ZINC (ZDDP) is widely recognized as the prime ingredient to safeguard flat tappet cams and valve train components within engines with high valve spring pressure, effectively controlling aggressive camshaft profiles. This protective additive is essential for older vintage engines produced when Zinc was the primary component used to provide the last measure of protection against catastrophic failure.

The proper amount of ZINC must be used in relation to engine oil to ensure the ideal level of protection. Zinc provides the appropriate ratio of 3000-3200 ppm of the ZDDP additive to treat six quarts of engine oil, ensuring proper engine break-in and protection of high-pressure valve train components. Blended with a light base mineral oil, this formulation aids in the quick and complete dispersion into any engine oil, enabling fast activation and protection during the initial startup.

For maximum protection, ZINC must be reapplied to the engine oil whenever the oil and filter are changed. The concentrated REV-X ZDDP ZINC Oil Additive and Treatment is designed to treat up to 6 quarts of any type of oil. It works exceptionally well in manual transmissions, gear boxes, rear ends, and any other type of oil-lubricated system where Zinc was the primary ingredient to prevent metal-to-metal wear.

The ZDDP / ZINC in engine oil creates a protective film that coats the engine parts with an anti-wear layer, acting as a sacrificial layer that wears away, preventing damage to vital engine components. This is particularly beneficial for flat tappet motors, where the constant contact between the cam lobe and the flat surface of the tappet generates high temperatures due to friction. Without the ZDDP-derived protective film, this heat and friction would lead to accelerated wear of the lifters and cam, potentially resulting in engine failure.

ZDDP is crucial for engine break-in, as this process involves significant heat and wear as engine parts conform to their respective surfaces. The ZDDP-derived sacrificial layer prevents excessive wear during this crucial period, ensuring proper sealing of the piston rings and proper setting of the lifters to the new cam.

One 2 fl. oz. bottle of REV-X ZDDP Oil Treatment with Zinc can treat up to 6 quarts of oil, providing the preferred ratio of 3000 to 3200 ppm of Zinc, which is the optimal level for older engines with flat tappet camshafts. This ZDDP-based treatment can be blended with any synthetic, semi-synthetic, or mineral-based oil, offering the ultimate protection for late-model engines, including high-performance race engines.
