I am running Valvoline SynPower full synthetic 75w-90 in my 9.25" 3.92
sure-grip equipped differential. I use 2 bottles of Mopar limited slip
additive/friction modifier along with 2 bottles of the gear oil for a
change. I change it every 2000 miles when I do the rest of my maintenance.
My sure-grip unit seems to be as effective as any other one I've seen and
makes little to no noise with the 2 bottles of additive in it. Differential
stays nice and clean with very little wear to the gears or sure-grip unit
with the fluid and my maintenance intervals. HTH,

Has anyone changed to Synthetic gear oil in a 9 1/4 with a sure grip? If
so,did you use any additive? I use my truck primarily for drag racing and I
am about to change the fluid. I would like to use Synthetic but I don't
want to do anything to hurt the sure grip.
Thanks,
Wayne
