Hey, I know this has been touched on a few times but cant seem to find what im after, the car has 315,000 kms so just wandering whether i should use a 80w-140 LSD oil or a 90w LSD oil in the rear diff?
Cheers
Joel

We use a straight 140 in units with bigger tyres, more horsepower normally.

In std tyred retiree's vehicles we sometimes use a 85-90 instead, in our colder climate.
