10w-90 gear oil and 10w30 motor oil

Postby dblact38 » Mon Mar 23, 2015 5:53 pm

I want to change the fluids on my 1952 cub. My buddy has some extra 10w-90 gear oil for the transmission and 10w30 motor oil for the crankcase. Are these fluids ok to use in my cub? Any info will help ! Thanks in advance

The 10w30 is fine for the engine. I have never heard of 10w90 gear oil.
It is common sense to take a method and try it. If it fails, admit it frankly and try another. But above all, try something.

Me neither, check again, it is probably 80W-90. That's what I use anyway.

Yes, you are good to go.
