i have had good experience with this oil on many cars and have a bunch left in the garage. I dont see any reason why the RR wont like it. Any1 have a reason to not use it?

or 0w-50.
Mobil now makes an EP which performs about as well as Amsoil in wear tests.

I went to 15w-50 Mobil 1 to fix a persistent knock I had (with 0w-30 Mobil 1) at about 75,000 miles, and lost 1-2 mpg. I will try 0w-50 next change.

The results of oil testing to accepted industry standards convinced me that Amsoil and Mobil 1 EP are the best for most vehicle. On engines which require frequent changes (like the old Rover/Buick engines), these are not really cost effective, but they do reduce lubrication-related wear.

The "0W" tells us that it will flow well at low temperatures, while the "-50" tells us that it will adhere and provide lubrication at high temps. Down here in Texas, the 15W-50 will be fine, as would 10W-40.

I have not gotten a copy, but my indy shop tells me that the 2003-2005 BMW-engine Rovers have a TSB for a knock, which recommends using 20W-50 oil to resolve the noise. It sounds like the Vanos units on these engines may be subject to a problem which increases sound emissions - which may be helped by higher viscosity oil. I found that my noise decreased with heavier oil.

My reference was for the 2003-2005 BMW engine. And yes, 15W-50 is heavy, but the LRNA TSB recommended 20W-50. I have lost 1 mpg since the oil viscosity change (and another after going to 18 wheels and slightly over-sized Goodyear Silent Armor tires.) I may change to 10W-40 for the remainder of the winter on the next change.

Land Rover of Minneapolis service department tells me to use Mobil 1. We have 90 degrees sometimes in the summer and as low as -20ish in the winter.
