8.8 with 4.10 gears, 75w90 or 75w140 and regular or synthetic? Ill run friction modifier with either oil choice.
Differential fluid is where it all starts when acceleration is endured. Gears wrestle and spin with superior fluid, eliminating inertia is the core of a machine moving withe little to no effort, and transferal of energy.Does gear oil really change anything? I've seen people recommend different things, but I've never heard of anyone giving any reasons or what effect any different ones would have. Far as I'm concerned they just make sure the bearings don't explode.
I am running Amsoil 75w90 gear oil. It can run up to 300,000 miles with no drain. And I am using Motorcraft Friction modifier. I did this when my rearend got rebuilt from scratch with the Ford racing 3.73 gears, it has clutches, new bearings etc...
The rearend is so quiet I can hear the transmission and exhaust, and I can roast both tires off idle, no one tire fires.
