I don't think the diesel is available in the US so these figures are most likely for the petrol one.
Don't forget, the US gallon is about 20% smaller (16 floz in a pint) than the UK one (20floz/pint) so they would translate to approx 15 city/21 highway for UK measures.

I have changed from Morrisons diesel to BP Ultimate.
Morrisons at 122p per litre gives me 22.7mpg
BP ultimate at 132p per litre gives me 26.5mpg.
That is an 8% increase in price, for a 17% improvement in economy.
Will give shell a try as well, see if there is an improvement at a lower increase in price. May the road rise with you.
May the wind always blow at your back.
And the sun always shine on your face.
May God always hold you in the palm of his hand.

My D4 is now only 1 week old and I've used 62 litres for my first 590 kilometres which I make to be 9.5 litres per 100 kilometres (about 26.2 mpg) - almost exactly what LR quote in the book. Interestingly, the computer tells me that this is my consumption as well, so seems to be accurate. Digital guage also read a quarter full when I topped up. Since the tank is 82 litres and I put in 62, that leaves 20 litres in the tank (about 1/4)  Land Rover Series IIA 1967

Doing the math, that's 9.5km/l, 10.5/100km or 26.8mpg.
Mine (D4 2.7) tells me it's doing 8.9l/100km on the computer, but in real world math is 9.7 on one fill and 10.3 on another (had more figures, but a phone melt down lost the spreadsheet I carry and I stupidly didn't back it up).
On the first set of figures I'd done (about 6 fills) I'd worked out the the computer is 1.4 - 1.6l/100km wrong. Funny thing is, the distance to empty id pretty much correct!

In my haste I calculated kilometres per litre and got 9.5. However, this is really about 10.5litres/100 kms. I'm still very happy with this, but my computer is showing (checked it just now) 9.3 litres per 100 Kms! In other words, it's under-reading by about 1.2 litres per 100 kms. I wonder if this under-reading margin stays constant over different fuel consumption rates and driving conditions? The dealer here in Perth also told me that it takes up to 5,000kms before the economy improves (that's their experience with demos I guess) - hopefully it will drop down below the 10litres/100 km by then.

I don't think a floz is the same size either... see following from WikiPedia (so it must be right!)
Quote:The U.S. liquid gallon is legally defined as 231 cubic inches,[2] and is equal to exactly 3.785411784 litres or about 0.133680555 cubic feet. This is the most common definition of a gallon in the United States. The U.S. fluid ounce is defined as 1â„128 of a U.S. gallon.
The U.S. dry gallon is one-eighth of a U.S. Winchester bushel of 2150.42 cubic inches, thus it is equal to exactly 268.8025 cubic inches or 4.40488377086 litres. The U.S. dry gallon is less commonly used, and is not listed in the relevant statute, which jumps from the dry quart to the peck.[2]
The imperial (UK) gallon was legally defined as 4.54609 litres. This definition is used in some Commonwealth countries and Ireland, and is based on the volume of 10 pounds of water at 62 °F. (A U.S. liquid gallon of water weighs about 8.33 pounds at the same temperature.) The imperial fluid ounce is defined as 1â„160 of an imperial gallon.

I didn't know that & stand corrected 
Given this info my numbers above should read 14.4/20.4 instead of approx 15/21

Sorry, didn't mean to sound critical! Just did the math for my own benfit, and found you're in the same region I am, which is good for me/my figures.
Other thing is you're 'error' in the computer is comparible to mine. Filled yesterday, and the difference is 1.2l under the manually calculated figures. I'll have to bring this up with LR and see if they are willing to try to fix what is an error that should be easy to fix.

Hi Discomania, no problem - when I got home my son pointed out that I had the numerator and the denominator switched around and had calculated it incorrectly. At least our two cars are consistent in their under-reading which is good to know. I suppose as long as we're aware of this it's not really a problem, but would be good to fix. You're a bit ahead of me in kilometres since my car has now only done 620 kms. We plan to take it on a long run down to Albany (south coast of WA) this weekend so should clock up about a 1,000 kms. Will be interesting to see what mileage I get on this trip based on actual consumption and compare it with the computer. I need to know this since I tow a heavy boat to Shark Bay each year and the fuel stops up there are few and far between. With other cars I have on occasion only just made it to the next fueling stop when towing. Will be doing a trip to Canberra (Daughter lives there) via the Nullabor, Snowies and Vic Alps this coming xmas. Land Rover Series IIA 1967

I don't often tow anything, however we are looking at an off road camper trailer this year - although with the speed the year has gone so far, NEXT year might be more likely.
I look forward to reading what mileage you get on the trip.

550 mile round trip today mostly on motorways. Averaged 55mph (despite seeming to be at 72 on Cruise Control all the way) and the fuel figure was 31.2 mpg. The same trip in my D3 was 26.6 mpg at best under very similar conditions.

I am sure that you'll find that in "real world" driving you won't get anywhere near the manufacturer's claimed mpg figures for any car.
Once again, just don't fret about fuel cost - it is just not an issue compared to depreciation. If depreciation is generally lower than an average car, you'll be much better off all round.

My issue is NOT with the mpg (l/100km). I'm more than happy with 9.7 - 10.2 l/100km. My issue is the computer (seems to have settled) is telling me 8.6 - 9.1l/100km It's 1.1l/100km optimistic.
As stated before though, the 'distance to empty' seems fairly accurate for my figures. Based on the 82l tank, it tells me I can run for 783km before 'empty' - should probably be around 800km, but I'll not quibble as it SHOULD stop me running the beast dry!
It's currently telling me I'm using 8.4l/100km for the 60km trip I did today too so that should be 9.5 which is really good for a 2.5ton vehicle

Went to see my car in the dealership today. Seems to have travelled 400 miles back from France on 1/4 of a tank. Mind you it did take LRA three and a half weeks to get it here so they probably pushed it most of the way.
