Have always used zinc supplements on rebuilds, a friend said put this in your RZR, and I did, No complaints, and Rislone has been around for years, not sure if it helps or not, but it's cheap enough to add in the hopes it helps..

The reason to add this to an oil change regimen is when you have a motor that has a flat tappet camshaft. Including this zinc additive to each oil change will protect your camshaft and lifters from premature failure due to changes in oil regulations that are present today. If you have such a motor I recommend this product as it will help you preserve the performance of your engine. It will help keep it running smoother with less engine noise and a lower temperature. Possibly resulting in better mileage and less leaks down the road.

As advertised

A necessity for older car engines.
