2016 XJL 3.0 v6

What is OEM fluid for the rear diff?

BOT 720 Is listed for x351 5.0 v8 rear diffs, but I can’t find the fluid for x351 3.0 v6. The 720 is listed for the front diff in the 3.0, but no spec for rear diff.

Would they have different fluids for front vs rear differential? If so why?

 

75W90, at least for the standard differential. I think it's the same for the e-diff, but you'd want to double check that. It's the same front and rear.

 

No the E-Diff needs special fluid! It is not standard 75W-90 gear oil. These have CF clutch plates and have specific lubrication requirements.

But it does need 75W90 weight and not 75W140 weight

 

Yes that is a good point.
