I have a gallon of this stuff left over from my D-90 and was wondering if I can use it in the 1974 Series III gearbox, transfer case and differentials. Seems like our hosts offer the Amsoil 75w-90, but when I go to the Amsoil page it seems like the Manual Transmission & Transaxle Gear Lube 75W-90 (see link below). So why do our hosts not offer this and is it better? I want to put the best stuff I can in there and am not too worried about cost, any ideas?
