Without starting a battle over oil, hopefully, have people here looked at the Shell Nautilus fully synthetic snowmobile oil? It is API-TC rated, along with a pile of other ratings, and readily available here in Canada at Canadian Tire. The only Seadoo dealer near me is not that close and I've been frustrated with them for other reasons so I'm not feeling too loyal. I'll try to post a picture of the back of the container which shows all the ratings. Just wondering if anyone here has used it.
