Diff lube clarification

Ive read thru the forums and what i see is 75/140 synthetic will work,i went to the store and can only find 85/140 synthetic and it says limited slip on the bottle.
Will this work? Or should i try to find the 75/140?

By the way its a 98 ZJ

Thanks in advance for your answers

It will work. Limited slip diffs require a friction modifier additive. While it is necessary to have this for limited slip diffs, it will not hurt your open differential.

75w-140 is more heavy duty, like for towing. what you're supposed to use is 80w-90.

Yeah, but, personally I would have spent that in my local community instead. Not kicking you for it at all. That is your choice.

well in that case, im paying the fed ex guys, lol. plus its not really my community. its down the road a bit in the next town and thats where i bought some paint, brake cleaner, and the differential gaskets anyways. if it was my local napa, then i would have spent the money there cause there nice guys and i go in there all the time. and on a side note, it wasnt the same brand gear oil. advance had lucas, the one online was valvoline high performance.

I havent put it in yet as im giving the rtv a night to form a good seal,,so should i take the 80/140 back and get what just regular 80/90?
I usually have a company truck, so i dont drive much but that may change and i may be putting some decent miles on this vehicle and im just looking for good lubrication and protection

the 85-140 you found is fine, i used it to fill up my rear diff as it was a little low.

Altho i would use a bottle of friction modified from the dealership if you are replacing all the fluid.. I dont think that bottle you found actually has friction modifier in it i dunno, if its the same bottle i used mine didnt mention that it had it in it... only that it can be used in limited slips
