Hey guys, I'm new to the site and to the whole ATV thing as well I suppose! I just purchased an 08 Polaris outlaw 525 IRS and I'm unsure of which oil to run in it. I know a lot of people use the rotella 15-40 but it kind of scares me to run that. Any opinions on which oil I should run or what people have had luck with? Also it idles normal but once it gets warmed up it almost seems like the throttle sticks open a bit or something. It idles higher then it ahould after being warmed up. Would seafoam fix this? Thanks for the help in advance!
