What is the "hypoid" in hypoid gear oil? Isn't it just gear oil or is there something special about it? I have a lot of 80 weight hypoid gear oil that's a liquid and not a grease. Just as soon use it if it's ok.
The shop manual that came with my 1977 India Bullet actually specified greasefor the gearbox I think that this may have been common practice in the 1930swhen the Bullet was concieved, probably didn't leak out past the felt oil seals of the day!
