Especially with the larger tires and the power available from the large motor, I think a MT would benefit from the heavier fluids for winter driving.

You speak as if you have driven in the shete...

Great info all, and I think what I'm going to start with is some 300k in just the rear. The STP oil treatment I am currently using is already equivalent to
1k or more (a guess), so I will see how the front behaves.

I'll try to explain this just to see if it makes sense to anyone else: with the rear spooled, and the front and rear diffs directly connected, ie. no CD, the only way the front diff unloads is if BOTH rears are lit. Since that is more of an issue in the slick, that's really my only reason for maybe needing to thicken up the front as well. But still less than the rear, as discussed.

So where is the best place to get some 300K fellas?
