Cutting to the chase, the good Dr. Evil recommends plain ol' Dino 80w90 GL5 rated hypoid oil.

Our trannies haven't changed. If you want something more exotic than good old SAE 90 GL-5 gear oil (why?), then Swepco 201 is still the favorite aftermarket goodie.

I say buy cheap dino, then... because it's cheap... fuching change it every couple of years.

I like Kendall dino when I can find it.

I used to be a swepco lemming, really I never liked it that much, shifts like shit. Expensive shit.
Since I still have some I toss in a couple of pints each change, just because the pretty blue colour is easy to spot if you have a leak.

I still swear by Swepco 101 grease though, I love it!
It doesn't mix with water, I can use it for everything from wheel bearings to CV's, cars, my Fiat diesel tractor, lawn tractor etc. One grease for all.
I buy a case every couple of years, just bought a new case not long ago.

I use the Sta Lube gear oil. I didn't like the Swepco gear oil. I love the Swepco 101 grease though.

I've been putting Wal-Mart crap in mine every other year for about 12 years now.
No issues yet, and I average about 150 miles per week.

Ok,..Great...Iam good with dino I just needed to make sure,!!! Thanks, Frank
