GGGRRR Oil Question

[Felt]

I have read a lot of information on this site about oil. My problem is supply, my local auto store wants to sell me Lucas gear oil and i have heard a lot of negative things. My question, Shell Rottela 85-140w is this to heavy? I can buy this at walmart ( i dont want to give this company my $) but this is about supply and living in the middle of nowhere, my choices are limited.

Romer, I have read all your posts about oil, thankyou i think i am more informed than my education permitts I have been lurking this site for years it helps me maintain my LC and has saved me thousands of dollars over the years. Seldom have i had to post a question because of all the information and talented people that follow this site Thanks for being there and keep up the good work.

I think you mean 85w-140, correct?? But to answer your question... Yes.

I use Chevron Delo 80W-90, but have to go through a local Chevron distributor. I assume you've looked through the phone book and don't have a distributor locally?

A lot of people use Mobil 1 synthetic 75W-90, which is available at most auto stores but obviously more expensive.

Yes 85w-140 & Yes, i live in the stick and my choices here are limited. Thanks for the quick response
What effect will this have on the f&r diffs?

You should have no problem finding 80w-90 gear oil, even in bumfuctegypt, try another store. Walmart will have it as well as ANY car parts place.

Dunno exactly, probably reduce gas mileage for one. Cary's the resident oil guru, but being that far off manufacturer spec., can't be good.

It's hard to believe you can't find 80W-90 around there somewhere (I've got a sneaking suspicion you bought a bucket of 85W-135 that's sitting in the garage, and that's hendering your search ) otherwise you might have to make a trip outside of stickville on this. That or check the internet. I know you can get Mobil 1 synthetic shipped to your door.

I use 85w-140 in everything .
The only thing Ive seen a "issue" with is on my 40 in the cold as its a little stiff shifting for the 1st few minutes

Works fine just takes awhile to get it from the bottle to what its going in

OK Guys, I do have a bucket full, it's for my tractor. No honestly i just did not want to go to Walmart. I will suck it up and go tonight.
Thanks again for responding I'm sure OIL questions get a little annoying.
cheers, Felt

Oh Crap! Do you use this in your T-Case? What's your gas milage like?

What's your gas milage like?

The reason I bring up reduced gas mileage is a result of when I blew my inner axle seal and had a mix of grease and gear oil in the diff (which I'm sure is worse than using 140 weight, but in my case it wasn't by choice). Over this same time period I experienced a drop in gas mileage on the order of 1.5 mpg. The only thing I could attibute it to was the birf soup in the diff. I guess it stood to reason...., thicker fluid = more resistance the gears are slodging through = worse gas mileage. I'm aware of at least one other that has experienced the same thing.
