ZINC or ZDDP is widely known to be the prime ingredient to protect flat tappet cams and valve train components within engines using heavy increases in 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 prime additive used to provide the last measure of protection against catastrophic failure. It is necessary for the proper amount of ZINC 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 parts per million for proper engine break in and protection of high pressure valve train components. It is important to understand that ZINC is blended with a light base mineral oil that aids in the quick and complete dispersion into any engine oil for fast activation for protection on first startup. For maximum protection ZINC must be reapplied to engine oil when the oil and filter are changed.Benefits Of Rev X Zinc (Zddp) Concentrate Engine Oil Additive‣ Provides Maximum Protection For Engine Break In. ‣ Protects Flat Tappet Camshafts (Hydraulic Or Solid). ‣ Provides Increased Lubrication Of Roller Lifter Bearings (Hydraulic Or Solid). ‣ Protects Upper Valve Train Components. ‣ Provides Maximum Metal To Metal Protection. ‣ Protects Vintage Car Engines. ‣ Protects Muscle Car Engines. ‣ Contains No Other Extreme Pressure Additives.

No hay diferencia si se trata de un camión o automóvil. **Q: Zinc additive products... some containres are 2oz and some are up to12oz. Is more better, does volume make a difference?** A: All more volume does is add more base stock oil to the product. A 2 oz. bottle of REV-X Zinc ZDDP Oil Treatment will give you 3000-3200 parts per million (ppm) of zinc when blended with 6 quarts of oil. In this case more base stock oil is not needed or better. Because you can't control the viscosity of the base stock in larger bottles of additive you risk changing the viscosity of your oil. The most important part is what the final ppm number is, you don't want too much but you don't want too little either. We have developed and tested our additives to be sure it provides the correct level of protection without changing oil viscosity through the use of unneeded fillers. **Q: My 351W in a classic mustang uses 5 quarts, so im assuming I should add only 1.666 ounces?** A: You could, but by using the whole bottle you are just adding more zink to the oil which wont harm anything. I use this all the time in my equipment and have oil analysis performed at oil changes. It shows up as high zink content but does not harm anything. **Q: I have a 2004 Toyota Avalon and a 2002 vw Passat would this work for that in my engine oil?** A: Not needed your engine is new enough but you can if you want to feel like you have to have added protection. This is for older cars pre-2000 ## Customer Reviews ### ⭐⭐⭐⭐⭐ A must have for older flat tappet cam engines. *by J***P on 3 March 2026* The most highly recommended brand. A must for older motors with flat tappet cams. ### ⭐⭐⭐⭐⭐ Great *by R***T on 17 June 2025* Great price fastship ### ⭐⭐⭐⭐⭐ My gosh . . . *by S***G on 1 March 2022* I actually got this for an older Jeep 6 cylinder because I read great reviews about how those engines really need Zinc - and how this product helped a lot of people that used it. So I got the 2-pack thinking, 'What the heck, I'll put one in the 2007 Cadillac SRX 6 cylinder . . ." With the engine running, I opened the oil fill cap and took note of the overall 'noise level' of the engine - it was pretty quiet with what I'd call typical 'ticking.' I then added this Rev X and was astonished that in 30 seconds - as this stuff circulated through the oil and engine - the sound of the engine became almost silent! Seriously and sincerely astonished! Can't wait to put it in the Jeep! ## Frequently Bought Together - REV X ZDDP Oil Additive - Zinc & Phosphorus (2 Pack) - WIX 51085XP Heavy Duty Lube Filter --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/385823188-rev-x-zddp-oil-additive-zinc-for-flat-tappet-cams](https://www.desertcart.hr/products/385823188-rev-x-zddp-oil-additive-zinc-for-flat-tappet-cams) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-23*
