****************Allen do not run synthetic in your air cooled motor use 15 w40 rotella or another diesel grade oil or aero shell 15 w50 if your engine is built to looser tolerances. the synthetic won't wick the heat off the heads remember my post about the engine breaking a valve .
if you have a belt drive don't worry about it if not here's what I did. my quads are all wet dics I run rotella 5-w40 hd diesel oil in my bombardier my little Suzuki and arctic cats ran years with synthetic mobile 1 the engines wore out before I had a clutch issue. automotive oil is not recommended in wet disc clutches yet ,I have never had a problem, and most had more miles on the odometer before they broke than you all would ever put on them in a life time.****************
I just bought a UTV "Ranch Pony" from BMS I think the Motor is a "HISUN" from China that is a clone of the Yamaha RINO. When I asked the Importer about using Castrol "EDGE" synthetic oil they said fine. Now due to the wet clutch and or Drive Belt I read where the oil should have the "JASO" rating.
Any one ran the syntech "EDGE" in there UTC.4stroke. Thanks in advance for any info. Vic.

In the engine ? Cases ?
Do you feel its worth the cost ? Do you see any improvement in performace
