Oil Additive

Features 5

  • 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.

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. REV-X ZDDP ZINC Oil Additive and Treatment will treat up to 6 quarts of any type of oil. Works great in manual transmissions, gear boxes, rear ends and any other type of oil lube where Zinc was the primary ingredient to prevent metal to metal wear. 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. 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. Rev-X ZDDP Oil Treatment will treat up to 6 quarts of oil with one 2 fl. oz. bottle of REV-X ZDDP Oil Treatment with Zinc. Will treat your engine with 3000 to 3200 ppm (parts per million), which is the preferred ratio of Zinc for older engines with flat tappet camshafts. REV-X Zinc ZDDP Oil Treatment can be blended with any synthetic, semi-synthetic or mineral base oil for the ultimate protection for your late model engine. Designed and proven for high performance race engines. Reduce or eliminate the chance of a catastrophic failure caused by metal to metal contact in your engine.

Buddy filled diesel skid steer with automotive gas engine oil. Used this to help.
We all know that guy who will buy a $65,000 machine and then only service it once a year with the cheapest oil on the shelf from Rural King or some other place with ultra cheap, home branded, questionably quality oil. Yep. That is my good buddy. So I go to the shop a couple weeks back and he is re-filling the skid steer engine with some ultra cheap, totally not to spec, gas engine oil. I question him and he states that it is perfect oil for the machine being 5W-30. I ask him if it meets the SAE ratings for the diesel, he repeats back that yep... it is 5W-30. So I go grab his New Holland book (C232 track skid steer) and look up the oil requirements, then I look at this junk oil, and I try to explain to him the SAE designations on the back of the bottle and the SAE requirements in the book. He looks at me like I have 3 heads and repeats that it is 5W-30, it is totally good. Someone.... kill me please! He has no clue what I am trying to explain. So I couldn't sleep knowing what he is doing, and I ran to Amazon to see if I can at least get zinc to add to the wrong oil and try to help the cam followers and rockers survive this next year. I found this. I ordered a few bottles and had them shipped to his shop, and I explained to him that these need to be dumped in to at least make an attempt in not prematurely wear the engine that likely is worth $20,000 or more! So the real question is, will he actually dump these into the machine, or will he toss them on a shelf never to be seen again? We may never know. But I bet next winter he will once again shop for the cheapest oil on earth to put in a machine that costs as much as some peoples home. He is who he is, you can never change that. ... show more

Great product

Use as directed, when needed, and you'll be good to go.
A must have if you have a need for a ZDDP additive. This won't fix your worn valve seats, leaking piston rings, seasonal depression or gout but it will improve the lubricating properties of a quality oil in a properly maintained motor for your longevity goals.
