Mobil 1 Gear Lube or Red Line Rear Gear lube?

[rsimoes]

What do you suggest?

pretty much all i use in anything i own with a piston in it is filled with either Mobil products, or Redline.

I suspect they are both top of the line gear lubes, just use one in your viscosity grade, being sure to get one that has/does not have the slip addititive, depending on your diff positraction. I have a ford 8.8 with the Traction Loc, and presently run the Redline 75-90, not much gear wear for all the "abuse" i toss thru it.

They are both good products,

I used Mobil 1 in my IRS and it made noise. It Didn't make a whiney or whirring sound but I could hear it working.. I went back to Valvoline 90 wt for the powr lok.
