Going to be doing a Diff oil change on my front Dana 60 Axle. Ford recommends 80W-90 Synthetic for the front axle. I plan to do a fair amount of drag racing this next year and I'm wondering if running 75W-140 in the front has any drawbacks? I will be running close to 100mph in the 1/4 mile in 4Wheel drive and figured maybe the thicker oil would be better. The gear lube of choice will be Amsoil Severe Gear. Thanks in advance!
