I have a question about the fluid in the rear-end of my truck.
I have a 2000 Ford F-150. The tag on the axle says to use 75-140 synthetic. I have read that the 75-140 is not recomended by some Ford techs.
Should I use 80-90 Amsoil with the Ford friction modifier?
Should I use 75-140 Ford with the Ford friction modifier?
