You will be good with Amsoil general purpose grease,however Toyota likes moly in the grease,as Im not sure of the moly level in their grease you have,myself I had a toyota 4X4 1985 and used Mystik high temp mostly ,and the truck had 248k when I sold it to a farmer to use to pull wagons,still had original driveline parts U-joints seals etc,also used Mystik 75w-90 semi synt in punkins,tranny etc Mystik worked fine for me.BL
