Dont have a manual. What oil is best to use in the automatic clutch tranny of my 83 atc 110?

 

I like the Honda GN-4 oil I get from local dealer. Another one I like is Valvoline Atv Oil which is good for wet clutchs which is what the auto clutch is. You can use mostly any ATV/Motorcycle oil. I don't recommend using just regular like 10w40 motor oil but many use it because its usually cheaper and easier to buy.





"Valvoline ATV oil contains a proprietary blend of premium base oils and advanced additive technology to help you get the most from your ATV.

Extreme Condition Performance - Thermally stable formula maintains proper lubrication to protect engines under extreme conditions.

Wet Clutch Protection - Optimal frictional characteristics for high torque, smooth shifting and proper protection of the wet clutch.

Corrosion Resistance - Advanced additives help protect against water, deposits and other corrosive materials to keep engines clean.

Maximum Horsepower - Proper additive balance for maximum horsepower.

Minimal Wear - Increased anti-wear agents minimize wear from metal-to-metal contact.
Shear Stability - Shear stable viscosity improvers better resist oil film breakdown"
