I've heard people say that before, but my experience has told me that it's usually not the synthetic that caused the problem.  It's usually that synthetic revealed the problem, which is a gasket that wasn't completely sealed or had shrunken.

AMSOIL synthetic motor oils are made of completely pure, ideally-designed synthetic base stocks, blended with the highest-performance additives available, and are fully compatible with all engine gaskets and seal materials.  In fact, because they are more painstakingly designed than petroleum oils, AMSOIL synthetic oils help maintain seal integrity better, rejuvenate shrunken seals, and extend seal life far better than conventional oils. 

What I like best about selling Amsoil is that we have a Tech Services Department filled with people who are passionate about performance and quality.  If you ever have a question, please feel free to holler at me or go straight to the guys in the lab.


They usually answer within 48 hours.

Are there certain steps to go from conventional to Synthetic? Do you need to buy different filters to? Do y'all make ATV oil?

Not really.  Just drain what you've got and refill with the good stuff. I don't recommend just adding more synthetic to the conventional you already have in there. It wouldn't hurt anything, but you wouldn't get the full value of synthetic.  You don't have to have a special filter, so just go with what you've always used there.

We do have the 10W-40 Synthetic ATV/UTV oil


But there is also the Formula 4-Stroke Power Sports Synthetic for those ATV racers who push things a little harder.


But wait!  There's Synthetic ATV/UTV Transmission & Differential Fluid too!



There's a lookup feature on the Amsoil website that helps you figure out what you need for your particular ride at:



Feel free to holler at me if you have any questions.
