    I run Redline Synthetic in my 14bff. It is 75W-250. My diff takes about 3.5 quarts of oil to fill. If I ran normal oil I would run the 85W-140 or whatever it is that the parts stores sell. It is the heavier of the 2 oils that the parts stores sell. The lighter stuff is 80W-90, thats what I run in my Jeep.
