The stuff in the the oil additive is molybdenum disulfide, an excellent high pressure solid lubricant. I don't know if they're compatible or incompatible, but they're two pretty different beasts. I've used moly additives in Porsche trannys with good results, where the main problem is gear friction (heat) and the synchros the the Porsche type and have plenty of grab. I've also tried them in BMW trannys and had the synchros (Borg-Warner type) go to hell. Nowadays I pretty much stick to whatever GL number the manual calls out. -Ed meed@mbari.org
