90w gear oil ???

[Italchic]

My shop manual calls for EP 90w gear oil for the rear differential. Where does one get this? The local parts stores have
80w-90 and 80w-140, etc. can I use these?

ive been running Mobile 1 80w-90 for over a year now -- runs fine

i got a small leak so every oil change i top it off and havent had any problems

the rear only takes just over 1 quart (1.3) i think so u might as well go with something good

either 80/90 or 80/140 will work fine

I got the 80w 90 and and topped off the diff. It wasn't all that low, but now it's full. Probably won't need to do it again for quite some time as I plan to only drive it till the end of Oct. and then store it until Apr.
