Hey guys just bought my first AC and I really like the Prowler...I gotta question though...Owners manual say's to use 5/30 but the dealer when I bought it said to use 0w40......Is this correct? Thanks in advance for you time and I'll post a few pics of it as well....

 

I also have an 08, and after some digging I found out that yes 0-40 is alright and arctic cat even sells an oil change kit for it. In the manuel you can see the range of viscosity and temps they cover 0-40 covers most of the range. have fun
