All,
I am a firm believer in synthetics and in Mobil 1. It is time for a diff fluid change and possibly adding the late model SD diff cover. I have in my possesion several bottles of 75w-140 Mobil 1 Diff fluid. Anyone running this? I beleive it is above the viscosity specification that Ford calls out, but then again, my truck only gets used in summer and warm-hot weather for towing. Anybody think this would be a problem to run?
