Well the oils been in 2days now of which today the cars been driven hard, and the gearbox is smooth as silk and theres no diff whine what so ever! Bloody marvellous! That was with Comma 10/40 Semi Synthetic in the gearbox and 80/90 gear oil in the diff, both also have some wynns transmission oil addtive in them
