What kind of oil is everyone useing. I am thinking about useing amsoil and was wondering if anyone has changed over to it. I have heard to only use Polaris but my problem is that polaris didn’t make oil they take the lowest bid to meet their specs and put their name at a mark up price. Amsoil has all the replacement fluids for Polaris and at least I know what company I’m buying from. Just my thoughts. Any help would be great.
