Diff Oil

I have a Jag LSD that was supplied by Wards Engineering some years ago - before I bought the kit. I am told that the oil should be Castrol LS. However this label apparently no longer exists. Can someone advise me what kind of oil (and how much - about 1.5 litres?) to put in the diff? Thanks


Bob

I used this oil that was supplied by my local motor factors.

Seems to work OK.

Diff Oil

Thanks Craig. I just went to HAlfords. I'll give my local motor factors a bell.

Hi Bob

Halfords don't seem to be much help for anything out of the ordinary.

Another option is a local Jaguar dealer. I believe they may sell an additive that you add to standard gear oil.

Hope you haven't got a limited slip diff if you are using standard EP 90 gear oil?

Diff Oil

Umhh! EP90 or not? Think I'll go to my Jag dealer in Glasgow. I'll pay over the odds but will get the right product.

I thought that ordinary EP90 Oil will attack the limited slip friction plates and you either end up with no limited slip action or you end up with a seized diff.

haven't tried it though so I could be wrong.

EP 90 is what was specified by my diff supplier. As far as I am aware the Jag standard diff requires SAE EP 90 and the Powr-lok uses SAE 90
From your post Morris XEP 90 is EP 90 with additives and states it is for "limited slip diffs that require EP 90"
