My 1st oil change was done through the dealer but recently changed it on my own 1.5 quarts came out of my quad to which I added the recommended 2 quarts of PS-4 full synthetic oil. It now reads way above the line on the dipstick like I overfilled it. Not only that but I bought the oil change kit from a Polaris dealer which comes with a filter but not even the same one that was on there. Done a whole lot of oil changes on other stuff but this one is upsetting even after going through the recommended procedure.
