REV-X Zinc ZDDP Oil Additive - 2 fl. oz.

Good stuff. Hard to find. It should extend my engine life.

This is for my 1985 nissan 720 decided to hold off using for now due to just changed my oil castrol 20 50 which has zinc to much can damage motor parts so next change

Good product but leaked in box. No cushioning or plastic bags used.

Quick delivery.

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.

Reccomended by my mechanic.

Si utilizas un 4.6L Stoker es obligatorio utilizar en cada cambio de aceite.

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.

This is a high quality ZDDP product that does what it claims. I purchased it not for a performance application but to add an extra coating in my engine to high pressure areas because my engine has a design flaw with its roller arm cam followers and I wanted to give it the best chance at surviving a long life. I also wanted to use it in my young engine to aid in proper break-in. So far from my oil lab analysis results, before, during and after I can tell that it does infact add the ZDDP it claims, does increase break-in wear, but then also produces lower overall wear on subsequent oil changes where there is just engine oil alone. Also wanted to let everyone know, instead of buying pricey 4-stroke small engine oil for your yard equipment, buy a bottle of this and add it to a 5-quart regular automotive oil and get the same thing but for less expense!

According to last exprimental time this 15% Achieve servics not badly

Necessary for flat tappet cam engine. Used half of bottle as per instruction.

Love it

Bought to help with the notorious valve tick. Added one bottle at oil change. Seemed to help. Bought another bottle for next oil change.
