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

I would say regular gas will be just fine, but being an air cooled motor, it will run cooler with premium!

Thanks for the tips guys. Looking forward to pushing a button to get it going now instead of pulling and that reverse is going to save my back! Bring on the ice and snow.

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.

Actually high octave fuel will make you low compression engine run weaker. It's made to reduce temperature and keep a high comp engine from pinging. So if you don't need it, then don't use it..

Why do say synthetic oil is no good for this engine?? The guy I bought it off of said he's used it since new. If I change now to dinosaur fluid will it hurt the engine? Thanks

Too thick, will just cause resistance. Synthetic oil is better for a high performance motor that is built with a lot less tolerances. Running mineral oil is your best choise.
