I'm new on here so.. I just bought a Hustler Xonei with a Kawasaki FX651v 22hp engine in it. When talking to my dealer he said that Kawasaki or Hustler is now recommending 20w50 now instead of the regular 10w30 or sae30 recommended previously. He said that by changing to 20w50 the oil consumption issue would be resolved. I have a Hustler Raptor with a FR691v in it and have noticed it does actually consume a little oil. It doesn't smoke or anything but it seems to blow alot of smoke when I start it after sitting awile. I have used Mobil 1 full synthetic 10w30 from the original oil change in my Raptor. Anyway, The question is do I break in my mower with 20w50 Mobil 1 motor cycle oil or 10w30 Full Synthetic?
