my owners manual calls for 75w/90 gear oil for the front and rear diff. is there any reason that you cannot use 80w 90 gear oil insted. the reason i ask is 80w 90 is plentiful. i can get it in gallon jugs, quart bottles whatever. 75w 90 only comes in quart bottle here and finding 5 in one store is almost impossible. just wondering what you guys think.:shrug:

The way I see it, the thinner oil is needed when cold so that the oil can get everywhere. When it is thicker, it might not get everywhere as well so you will have more wear on things until the oil gets warmed up.

i can understand that it just seems to be such asmal differance in viscosity
