Those castor based oils do mot mix well with others, I'd try a full synthetic if you must.
I think I've used castrol full synth in my spare bike when I ran out of Maxima Super M < not castor based
Imma just wait on it to come lol. And another question. I used the ratio rite cup and pour 22 oz. Of mtl in the tranny but its showing that it's full in the spyglass. I know its 22 oz cause like I said I used the ratio rite measuring cup so why is it showing full
