Anyone running Amzoil synthetic in the engine and diffs? I'm wondering if it would help quiet the gear whine at speed?

I think I'll replace the diff oil with Amzoil 75-140 full syn. What about the engine and transmission?

I just replaced the lube in the rear diff with Valvoline 75-140 full syn. Noticed no difference in sound level whatsoever. On another note, is it ok to run full synthetic in the transmission?
