Ya, fresh oil gets black quick in these 110's. I use Valvoline 10-40 4 stroke oil too

 

I change mine once a year or when it looks dirty. Changed it a few times when they were new. I had always used "car oil" in my air cooled Hondas, for a couple of decades on some of them. Never had a clutch problem with any of them..Like you say no need to spend big bucks to protect a low tech engine..

My KTM gets Amsoil 10w40 motorcycle oil...its got lots of expensive hard working parts inside to protect.

 

True. I usually run Rotella-T in my lawn/garden equipment, but my Kohler single, V-twin and hydrostatic drives are ridiculous bucks to replace.

Same theory I use with my street vehicles...F350(gas) and Tercel get Super Tech 10w30(walmart brand oil) My wifes STS gets Mobil 1 5w30.

 

Allright so can I get a clear answer on this cause I have read the forum and cannot seem to grasp it. These engines do have a wet clutch. (got that now). How and where do you fill them?? Mine does not have a dipstick for the transmission just one for the oil. I have two of these and we are getting ready to go for new years on a four day trip with them. I have been doing some maintenance on them this week and just cant seem to grasp the whole clutch issue. Thanks for the help....

 

Typically (as in almost 99% of the time, I can only think of 2 exceptions right now) wet clutch bikes, quads, etc share the same oil source. IE, the oil from the motor and transmission co-mingle......they are the same source.

So to answer you there is NO dipstick for the transmission. As long as the engine oil is properly changed and the level is correct your doing all you can for your transmission.

 

I checked the specs on your mini 110's. It says they have an auto trans on them which is like the 90cc quad I had, same set up just different size engine.

Anyway all you have to worry about is checking/changing your engine oil. The engine oil lubes the transmission too - it's all in one.

Just use a 10w-40 motor oil of some sort and you will be fine.

Some of these little engines may not have a dip stick for the engine oil just a cap you remove on the crankcase to fill and sight glass on the side you check the oil level by.

You should have got some sort of little manual with it, which should give you the needed info.

Don't know how long you've had them or what the story is. But be sure to check them over good for loose bolts and stuff on the front end, frame,reflectors and fenders. All frame, fender bolts should be installed with loctite. Doing this will drastically prevent little things rattling loose.

 

Another thing to remember, none of these little China wheelers (atleast none Ive seen) have an oil filter. Change the oil more then you normally would, it will do wonders.

When mine saw frequent use I would change the oil every month.
