There are lots of non qualified mpg numbers in this thread which I assume are from the trip comp. If so remember it lies/over-reads by 2 - 5 mpg. Well you didn't by a LR (well D3 in drag) to save da planet!!

MY FFRR under-reads by 2 mpg and the Disco is almost bang on the money on a fill up to fill up calc. 2014 5.0SC AB

Gone 5.0 SC

Agree the inbuilt mpg monitor is an indication not a calibrated result but 3 weeks into my 3.0 V6 I cant get it above 23mpg.

Just did Ayrshire to Aberdeen and tried a couple of settings (with a warm engine) and at avg speed of 65mph I still only get 22.5 in Dynamic on cruise and 23 in Drive and cruise. Now - MY11 RRS Autobiography TDV6, Orkney gray, tints, steps, daylight running lamps and allllll the toys!!!

Alex,
I had exactly that problem on my MY2000 MB E320cdi straight 6 engine,I'd taken it in for service and was asked to pop into the workshop,there was a channel running full length of the engine which the injectors sat in,it just looked as if someone had pored chocolate cake mixture in the channel and cooked it at gas mark 8.About 3 foot long 3inches thick block of black gooey mess,they broke 1 injector chiselling it out and subsequently needed another which failed later and had to have the head off to re-thread the holes that the injectors were screwed into,total cost about £1500 with a warning that it wasn't cured so got shut PDQ.

hhhmmm, that is normal for a mercedes e320, i should know, i had mine for 5 years, the problem is caused by the injectors seats lifting, mercedes fitted small bolts, that over time stretch, hence the injectors lifting, you can always tell when one is leaking, the cabin has an eggy smell. the cure is to have bigger bolts fitted, which mercedes now do.
i had 4 of the 6 helicoiled over the 5 years that i had it, it is a time consuming job, but if done correctly, the injectors do not break, the total cost was just under £400 for 4 injectors to be reseated over 5 years. 07,TDV8,Black, Black Heated leather all round, Rear Entertainment with Headpones & Remote, TV, DVD, Pure Dab Digital Radio, Sidesteps, Adaptive Headlights, sunroof, now working fuel burning heater )))

That's interesting,I think the problem with mine is that by the time it was spotted the injectors were embedded in the thick carbonisation and they broke them trying to get them out. MY2011 HSE Santorini/Ivory/Piano Black/Privacy Glass/TV .Sadly gone.

Well i am getting about 13mpg, so I would kill for your lowest figures

2011 3.0 tdv6 , 25.8 average but at 60-70 on a run about 39 mpg average

well im now enjoying the RRS V8, i to was clock watching, merce320 35+ mpg , RRS 22 mpg max
but ive decided its not worth it anymore, and just put the foot down 07,TDV8,Black, Black Heated leather all round, Rear Entertainment with Headpones & Remote, TV, DVD, Pure Dab Digital Radio, Sidesteps, Adaptive Headlights, sunroof, now working fuel burning heater )))

Had the car in at the local dealers (dealers Bryan, no sarcasm yet ) and the mpg on my latest trip south was 26 - 27 mpg. Seemed a software update check did the business. Thanks T&C Now - MY11 RRS Autobiography TDV6, Orkney gray, tints, steps, daylight running lamps and allllll the toys!!!

Are you sure

BTW My wifes Evoque .2 190ps is rubbish on fuel too

26.8 at present after 750 miles

Mate has an A3 2 litre diesel which is doing nearly 50   SDV8 vogue SE.
Corris grey and ivory leather + most of the toys.
Limited edition RRS model number 0001
Gone TDV8 RR Sport. Never to be forgotten.

Wife has an i8 BMW

Over 4000 miles my MY11 RRS has averaged 28.3 mpg according to the computer, all on A and B roads with no motorway driving. I haven't checked the mileage against actual fuel used.

I am convinced that how the running in period is done has a big effect on future performance and consumption figures.

26 mpg is good
