Thanks for the link.

It seems Jaguar recommends EP90.

Not sure then why people are talking about 75w140!

I’ll get some full synthetic 75w90 - which should work well.

Initially I used Castrol EPX-90, then discovered I had an LS diff.

I then changed to a 85W-90 oil with LS additive.

When I couldn’t locate this oil anymore, I switched to a Castrol 75w-140
with LS additive - this was recommended by Castrol for the X300 diff.

I never noticed any difference in petrol consumption.

Change the diff oil every 30,000 miles :wink: - mine has done 320,000 miles
and doesn’t leak or whine.
