Eric,
My truck has synthetic in it from the factory (white vent), but a web site you had posted compared synthetic diff fluid with Schaeffer dino and the dino seemed to work better. No air trapping and it climbed the gears. Now I'm confused.
Which do you recommend? I've always been sold on synthetics until you posted Bob's oil site and he compared gear oils.

The Schaeffer dino is good stuff, but we need to stick with synthetics in these trucks, Schaeffers does offer a full synthetic that meets eaton specs but the smallest container you can get it is 5 gal pail. even still, prices arent that bad, i think the pail can be had for less then 150.00.
