09 XP Waht oil to Use?

[CARBONDEATH]

I Just picked up my blue and white 163X and was dumbstruck with the price of parts. I asked my dealer for a free spare belt and the salesman looked at me as if my dick was hanging out. My 377 belt cost my $165Cdn with my 20% discount a little steep I thought. Anyways what are most people running for oil Ski-doo synthetic or Semi-synthetic. Just wondering if it makes a difference in performance or engine life. Semi is about $48 a gallon and full synthetic is $70 a gallon here. Haven't owned a Summit since 2000 so I am new to this all.
