Used Amsoil synthetic one time. Results were not good! Actually deformed the gears to the point of severe burrs on the edges of ring gear. Cleaned up the burrs and went back to the regular dino oil and those same gears were fine for a long time after that.

Only dino stuff in rears and trannies for me from now on.............
