Picked up an 800 REV sport yesterday. Dealer said Ski-Doo might not honor the engine warranty if they discovered (via an oil sample) that I wasn't using bombardier oil. He said it was up to me but I shouldn't take a chance at voiding my warranty by using a different oil. I have about 4 cases of Motul SnowPower 2T (a synthetic blend). Do you think I should have any problems? Will Ski-Doo honor the warranty? Anyone else using Motul? If so how do you like it?
