Do you mean the 90 wt oil eating the synchros in a 4 speed or 5 speed? The factory states that 20W50 is to be used in the gear box of the 4 speed (transmission)...and the 90W in the rear end...and on the 5 speed, the factory says 90W in the gear box (transmission) and the same in the rear end...so do I understand you are saying the 90W oil in the 5 speed eats the synchros? Obviously, I am a bit confused....
