Here too skidoodoug, once warranty runs out on my eltigre, that is what I will be running in that too, only use oem for now because I know the first question that will be asked in case of engine failure, " what kind of oil" a quick and easy blame out of warranty coverage. Have used for many years, still do on other sled, no issues
Ran Sea & Snow for years in my Ski-Doo. Didnt have any black puss oozing out my valves.
