I sense insecurity amungst these Sea and snow users. You don't have to justify your communist support and cheapness to any of us. Don't cry to me because your job went over seas. You buy from the enemy and they prosper. And what do we do? flounder. Amsoil because it works. dave m, are you being sarcastic? those valves are not clean. maj16, back to your question. If the sled is under warenty ask the dealer if your covered. I don't care what the ratings say, it is a matter of how much hassle you going to receive from the dealer if you have a problem. This is a huge gray area. Personally I would not put $12 a gallon oil in a $12,000 sled or 87 octane in a sled built for 93 octane, and neither does the guys I ride with. Cheap is Cheap.
