Mobil Delvac is the the good stuff. You can use it in your Front Differential, your Rear Differential, AND your transfer case too!
Treat your truck right with this premium synthetic gear oil from Mobil.
It's for trucks and heavy duty use. It is GL-5 rated, and it is supposedly better than the
Mobil 1 lube sold at retail auto parts stores. (see the Mobil Oil Delvac site for more info)
So here's the scoop, I bought a Five gallon pail of it to get bulk pricing, but I only need 2 gallons or less, so I have some extra to sell.
If you're local to northern Virginia (Arlington) or will be in the area, I'll sell you some at $40 per gallon... this way we all win.
You'll need to bring your own gallon jug!
Come forward. It's a good deal, and I really don't want to sit on three gallons of the stuff. I just couldn't see paying 50% more over buying in bulk.

I also found descriptive info on GL-4, GL-5 and MT-1 specs here.
API Category GL-4 designates the type of service characteristic of spiral-bevel and hypoid gears in automotive axles operated under moderate speeds and loads. These oils may be used in selected manual transmission and transaxle applications
.
API Category GL-5 designates the type of service characteristic of gears, particularly hypoids in automotive axles under high-speed and/or low-speed, high-torque conditions. Lubricants qualified under U.S. Military specification MIL-L-2105D (formerly MIL-L-2015C), MIL-PRF-2105E and SAE J2360 satisfy the requirements of the API GL-5 service designation.
API Category MT-1 designates lubricants intended for non-synchronized manual transmissions used in buses and heavy-duty trucks. Lubricants meeting API MT-1 provide protection against the combination of thermal degradation, component wear, and oil seal deterioration which is not provided by lubricants meeting only the requirements of API GL-4 and API GL-5.
This Mobil Delvac oil is GL-5 / MT-1 rated, so it has better protection against thermal degradation and component wear!!!
