i used vavoline brand in mine you can use sae 80 or 90 with ford friction modifier (#c8az-198546-a) or you can use an equivalent which most autoparts stores carry. i would recommend any reputable name brand sae 80 or 90 gear oil..but ensure you get the ford friction modifier or its equivelent..

My buddy uses Lucas on his race car both in the rear-end and the oil,and he swears by it...I recently adopted his formula to my ride and i've noticed a solid difference with the way the engine does'nt sound like a sewingmachine...as far as the rear-end i really did'nt have any problems before hand,but as a preventative maitinance measure i put the lucas in.
