I've used gl-1 I think it is in the past. I looked at rural king the other day and they dont have it. I was on vintage tractor engineers site the other day and he recommends 15w40. Is that right? I'd rather go that route if its legit cause its cheaper and easier to find. Its also what I use in my truck. Anyone go this route? I have an early 59. I know there are guys that have used whale blubber with no trouble LOL. I just want to be sure that I read that right on his site. So before I go dumping motor oil in the trans I'm here to see what my class mates think?
