I calculate mine click to click at the same pump, at the same filling station. The fuel computer is about 2mpg pessimistic.
|
|
The computer mpg was calculated over 80000 miles of filling up until full using the same pump when in the uk and comparing the manual result with the computer... why are you so distrusting Mr Snail, many small diesel and petrol cars are easily capable of high mpg these days...

Sorry about the confusion, b308. My post was directed at the OP who calculated his car's consumption over a mere 60 mile journey. My post just happened to be positioned after yours. Click on "View threaded".

Ah, that makes sense, sorry for the mix-up! ;)

60 mile return = 120 miles is not "mere" I didn't need to calculate anything - the figure is from the onboard computer wich is correct because I have done the fill up of the tank test before and it was within 1 mpg.

On the contrary, it is an extremely small sample to be anywhere near accurate - what about other variables such as ambient temperature, road conditions, tyre pressures, gross weight of vehicle etc. L'escargot was not just nit-picking, all of these things (and more) will have an effect on your MPG, hence calculating it over a longer period of time will take such variables into consideration. For example, I could go outside right now and get 39MPG on my commute home, but the same journey back in December wouldn't have yielded the same fuel consumption for many reasons.

21.5 in my Maserati QP, but only 900 miles on the clock so will get better.
|
|
Around 50mpg from '03 Focus 1.8 TDCi 115hp on motorway around 70mph, and 46-48mpg in mixed driving.
|
93MPG in a '73 Austin Maxi 1750.
On a local motor club economy run - I was beaten by a 2CV that didn't quite manage 100MPG. Much use was made of the ignition cut-out I'd fitted for coasting. One colleague, driving an auto, moaned I silently overtook him on a downhill stretch. IIRC we had to average at least 30MPH as well.
|
91mpg in a '91H Maestro van with the 2.0 Perkins diesel engine - Bedfordshire to Swansea and back on 4.75 gallons! It had a wheel bearing on the way out so I didn't exceed 50mph, which was pretty much idle speed in 5th gear.
Also scraped 75mpg out of my '95M Mondeo TD estate during the fuel strike of 2000, mainly by switching it off at rest and only travelling at 2/3rds of any speed limit ;-)
I remember the eerie journey down to Heathrow late one evening that week, on a virtually deserted M25, travelling at 50mph and not overtaking anyone!

My 2.5 transit (now retired) regularly returned over 40 mpg.
50 years ago the most popular British car ever the mini could do nearly 50 if driven carefully. Surely 100mpg for a modern equivalent should be the goal.

If they hadn't all bloated by 300-400kg on in the last 20 years, it would probably be possible on today's engine technology.
A new MINI weighs nearly twice as much as the original.

Renault Megan 1.9 cDi, 130php, 2007 with 30,000miles did 99.9mpg the other night. I had just filled up, reset the computer and the almost coasted home, hardy touching the pedals! On my Durham to Portsmouth weekly trip was averaging 55, best being 60mpg, speed average around high 60's. Worst 49mpg following traffic jams, or pushing to 80+mph.
Espace only 42mpg 2.2 cDi 150php.

Just filled the Volvo up. (S60 2.0T manual - 180 bhp). 505.6 miles covered. 65.02 litres to the usual second click of pump. I make that a whisker over 35 mpg. Combined, as mentioned above, is 31.7mpg
Oh and it's got just shy of 144,000 miles on the clock and is due a major service in the next couple of weeks.

Aha, just the thread for me as Im doing fantastically well recently in the fuel consumption stakes!
Old timers to this site may recall my photos posted 3 years back which showed an average consumption of 60mpg in my Passat 1.9 TDI.

However recently this car has surprised me even more, since after reading up on hypermiling techniques , I have now managed to squeeze out 700 Miles out of each 3 last full tanks of diesel in this car!
Im sure there must be disbelievers in this forum, but that is the honest truth!
My home to work commute is 4 miles , and I do a good amount of mostly short trips, the longest has been about 50 miles, on A roads.
I prefer country roads to A roads/motorways and touch the brakes only when I have to,and now have a very light foot on the accelerator but with superb torque can move like a rocket when it has to!

Passat DPF 1.9tdi?
Hypermiling techniques, light foot, short trips?
Good luck with the DPF, cylinder compression, injectors and possibly the turbo. Eeeking another 10MPG is compromising the longevity of some very expensive parts to replace. Spoil sport i know but its a common occurrence these days.

Hypermiling techniques, eh? One of which is glueing yourself to the back of an artic thereby reducing wind resistance drastically. The money you save on fuel you could put aside for getting the front of your car resprayed...

I'm sure there must be disbelievers in this forum.
Yes there are

You mean you think he's lying, or you think the trip computer is wrong, or something else?
EDIT: I assume you are referring to yourself; apologies if not.

all this tall of 55mpg + seems like a tall order.
Current driver of a Mondeo 1.8TD 2000 reg. 150k miles. Recently serviced less than 1500 miles ago. I get 540 out of 57 litres of fuel (full tank) have done the brim to brim technique quite a few times but can better 540ish. Im acheiving around 43mpg. Doing 150 miles a day.
60% motorway driving. 30% A road driving. 10% local built up driving.
Does 43mpg sound ok. Any way I can increase mpg. I almost cant beleive people getting 65-70mpg.

i get just under 600 miles out of the jag 2.0D xtype, with a very light foot.

Whilst the 1.9 TDI engine is a very fuel efficient engine I don't believe it is capable of returning 60mpg plus in a cat the weight of a a Passat in "real" driving. Perhaps driving down a flat road at a steady 50 but not on mixed driving over a realistic period.
I have a car with the same engine and there is no way it will return anything like an average of 60mpg and I am not a leaden footed driver by any means. Sorry I just don't believe it

BMW 520i Touring (2001/Y, with the later 2171cc 170bhp engine), two trips, Leatherhead-Oxford Peartree P&R, Leatherhead-Blenheim Palace, average 41MPG (combined figure according to Which? is 32) - for some reason, the car seems happiest and most economical at about 85mph. Also Rover 3500S, Morpeth-Leatherhead, 30MPG (claimed average 21), general A-road driving mid-20s of MPG.

These Passat TDi economy figures seem like fantasy to me. At a steady ,true, 70mph on the motorway my 1.9 PD Tdi 100ps Passat Estate always got just 42mpg. Confirmed to be very close to the overall figures achieved brim to brim on the trip. Had the car for ~140,000 miles from new and overall mpg was 44. Never had more than 50mpg indicated even when gently touring in France at 45/50mph.
My Mk 3 Golf 1.8GL turbodiesel was the most economical car I've owned and returned 54mpg on a long run. The 1.9SDI Golf gave much the same.
All other petrol cars I've owned over the decades gave ~36mpg IIRC.
