Hey guy. I recently bought a 2015 foreman used. Oil was changed shortly before I bought it and was fine when I bought it. Since I have put about 15-20 hours on this machine. I checked the oil today and noticed it was very thin, ran off the stick like water but still looked like oil. I drained the oil and noticed that it had gas in it. Has anybody else experience this? What could cause this. The fourwheeler runs fine and doesn’t smoke at all.
