I was wondering if any of you are using synthetic motor oil in your machines? I was thinking of running AMSOIL synthetic for atvs in mine. My neighbor sells the stuff and swears by it. Let me know what you think.
I have been running AMSOIL 0W-40 in my Grizzly for over a year now without any issues. No problems thru the summer and starts lots easier in the winter.
I run the amsoil in my grizz I noticed a definent difference. The bike started easier and ran cooler the fan didn't come on as much I want to put a temp guage to see what the temp runs.
