I just bought a 2004 Ski Doo Legend 380f with 1700 miles on it. The guy I bought it from said he only used premium gas and synthetic oil in it. I'm wondering if I can continue using premium gas or if the higher octane is not good for this motor? Thanks
Not a high compression engine, running low octane fuel will not hurt it. This engine wont like synthetic oil, you will loose a lot of performance. It will run just as long with mineral oil as it will with synthetic.
Just so you know running high octane fuel will never hurt a motor(until you get into something like nos), in fact high octane fuel protects your motor. Your sled doesnt need it though.
