gear oil

hello all, Im getting my truck finally back together and need to fill both differentials and my transmission (manuel) up. I was thinking about buying a 5 gallon bucket of gear oil. Some mystik jt-6. My rear end is not a limited slip, and I was thinking of running some lucas stuff through my tranny, Just wondering if anyone has had good luck with any particular oil, and about the lucas junk. P.S. how much will both differentials and a tranny hold? Thanks to all input

Dana 70 7 pints.

I've heard that Lucas is good cold, but when it warms up it doesn't work anymore. I just use good old fashion Valvoline 80-90 in everything.

Redline makes great gear oil.

also schaeffer's is good gear oil too.

Forget the Lucas, it does make the oil climb the gears but causes foam when heated, you don't want that. There is a demo of this process on http://www.bobistheoilguy.com where a tub of Lucas gets spun into a froth.
