this is going to be a really easy question to answer, and make me sound pretty dumb, but when i accelerate on my polaris 550 super sport the oil light will come on. I am assuming it is because some how the oil is getting low even though i just bought it from a dealer a month ago. what kind of oil should i put in it and is it ok to just put more in it? or do i need to take all of it out and put all new oil in it?.... please advise, im 20 and this is my first sled and im not very good mechanically.... thanks!
