Yeah, I'm afraid I am going to go with the list, neighbor,
manufacturer, manuals and guy who rebuilt my tranny. (My neighbor
tried the MT-90 in his, he said it took about 3 miles @ 35-40mph to
dis-enguage after he flipped the switch. He has since gone to 20W-50
and is very happy)
I agree with your thoughts on using the HD over the ND. Someone on the
list (IIRC) suggested the ND, but my other tranny with the HD shifted
beautifully, I am hoping that a little breaking it, with the detergent
will bring this one inline with that one.
The oil bottle recommends using ND for old engines that burn/leak a lot
of oil or for non-critical gas engines (whatever that means.) I guess
the thinking is the engine is shot anyway and this stuff is cheaper to
keep dumping in.
