I plan to be riding my '86 LT250 4WD this summer. It has been sitting for 2 yrs. I'm going to change the oil but lost my manual. What works best in these old quads?

Does the front differential use the same oil?


Thanx in advance

 

ok i have one of these old quads to. i put 10w-40 in mine and it hasnt trubled me yet

 

Thanks

The front end drained out nice and clean. I think I changed it when I got it. It looks like 20-50.

The engine / rear end came out black and smells of fuel or gear oil.
