Good evening gentlemen

1999 4/4 2 seater with Zetec 1.8 engine

I am planing to changing my back axle oil. The axle is a BTR with part number MRA 002. I read somewhere that due to a labelling error a few 4/4's were fitted with an LS axle by mistake. I jacked the car and checked that if I turn one wheel the other rotates in the opposite direction so I think this is a non LS axle.

According to MMC the oil to use is Morris lubrication Lodexol XFS 80W-140 Limited slip Differential Oil. They say that this oil is also suitable for non LS axles. A dealer said they use Castrol Transmax Limited Slip 75W-140 also saying this was suitable for non LS axles.
I would value any comments about the suitability of these oils for non LS.

Also, looking at a photo on Gomog of the drain plug bolt, it has what looks like an aluminium sealing washer, is that correct and is it reusable? If it needs changing what size is it and where would I obtain one from? Is there any sealing washer fitted to the filler plug and again if so does it have to be changed and if so what size and where from ?

Regards Tony
