I'm not ready to trust Land Rover circa 2003 yet. Too much has happened between us.

 

I read a post here by LandRoverMasterTech, and he says from what he has seen, full synthetic oil leaks past the crucifix seals in the rear main bearing cap.
I also coated the cylinders in my 4.6 block with Rotella 15w40, while it's on the stand.
The thick oil sticks on parts, and it takes a long time for any to drip off. Synthetic rolls right off.
Synthetic is all I have used in many cars and bikes, for alot of years (other than break in).
But, considering how bad these engines seem to leak in general, I think I'll stick with the Rotella for now.

 

the rotella is nice if you have buick and tdi motors. Use it in all the cars
