I have an Automatic 90cc Baja utility quad. I have been running mobil1 full synthetic since I have owned it (about a week). Will this oil mess up the trans? Or will this oil be fine? I read on some other posts that it might not be good for the tranny in these quads. I there a type of mobil 1 that would be better?

Thanks for the info...

It is recommended that with the centrifugal clutch not to use
synthetic oil or a synthetic blend as it is to slick, and could cause
premature failure of the clutch lining. In the summer
or in hot climate you should use a 15w-40 or 20w-50 motor oil and in
cold or cool climate use a 10w-30 or 10w-40 conventional motor oil.
If the ATV is not kept in an area that will stay above freezing then the oil should be changed
before the first freeze to prevent any condensation from freezing and causing any damage to the
engine. If the ATV is being rode in and out of a lot of water then the oil should be changed more
frequently. Turn the fuel shut off valve to the off position and crank the engine for a few seconds
then let set for 20 seconds and crank again, this will help prime the oil pump to keep it from a
dry start

this is a copy and paste of a typical ower's manual for a chinese atv 50-110cc with an automatic trnsmission, notice it says DO NOT USE A SYNTHETIC OIL.
