As I recall, the book says every 100 hours. I'm changing oil at 50 hours using the counting hour meter on the speedo.
The book cautions not to use automotive oil, but a powersports oil instead which has additives that are better for your engine. There are a lot of oil threads in this forum that have discussed (and cussed) different oils. Do a search.Changing my oil soon and I just need confirmation from someone. For those using full synthetic 0w-40 is this just regular motor oil like mobile 1 motor oil or is it special specifically for Atv/utv motor oil? And is 0w-40 ok to use?
