what type oil do these little chinese atv's take bottom of the engine there is a cap - havn't done anything with the oil I think I should maybe change it?? lol 10W-30?? 1 qt or fill it or what...

 

10w-30 or 5w-30, depends on temperature. fill to the dipstick etchings. they don't take a full quart though.
be dang careful you don't pull the wrong plug/cap on the bottom of the engine. one of them is for the cam tensioner. there's a lot of posts talking about that. i still don't know the fix/repair for that screw up. if it has a spring on top of that cap/plug, that's the wrong one!
so in essence, you got a 50/50 chance of not screwing up
