I've been running 600 wt oil in the gearbox, with some moly disulfide powder added. The box is basically quiet and shifts relativly OK.

I just drained about 80% of the 600/moly mix out and replaced it with Lucas Heavy Duty oil stabilizer. With about 50 miles on it I can say the first and second gear noise level is down some and the shifting is easier and smoother.

Shifting is aided by the gears slowing down quicker, which I take to mean the oil viscosity is staying thick even when fully warmed up.

So far, I'd have to say this is a good change for my A.
