It gets a lot of downtalk, but I love generic supertec oil from walmart. I have used it for years and years and years now. I have it in my go-karts, chipper engines, generators, lawn mowers, motorcycles, and several other engines that I have - and my class A and class C. It is NOT the best oil that exists, but it still gets a solid A for a grade on the report card from me. It is often packed by mobil. It is very inexpensive too. I also love marvel mystery oil. I put a couple of drops of that in my gas and oil. Just my .02. Otherwise my next choice is take the plunge and use mobil 1 sythetic.
