Title: Real world MPG
Post by: Andy A on 18 May 2014, 20:32:11
Thought it might be a good idea if we all post up our real cars average MPG along with the in town/motorway and driving style, transmission type. engine size and if it's a petrol or diesel.

When my car is on the road I will post mine.  :y

2.2 (manual) on LPG, get an average of 24-26mpg over a tank. Mixed motorway/town work, which is not too bad a 0.69p a litre  :D (Petrol it used to average 32ish)

3.2 (auto), gets a fairly solid 27mpg, not matter what it does. When I really started to like my 3.2 was 4 up with a very full boot, on a weekend to Bath and back, with lots of twisties, lots of over taking (4 up) still did 27mpg  :o

Aye I'd say 27MPG avarage in the 3.2 Auto as well.. Also seems to do that little bit more with Shell V Power Nitro.. Reached over 30mpg with mixed driving few weeks back, Sure it gets a few more miles out the tank too and runs smoother  :y

22mpg. Not bad that for its size.

3.2 seem to better the 2.6's by a reasonable distance :(

Its broadly agreeded the 2.6s are same on fuel as 3.2. But there is a massive performance difference.

23mpg on a long run is poor though. At a constant cruise should see close to 30. As I've seen 30+ out of the 3.2 on a 70mph cruise

Post by: TheBoy on 18 May 2014, 22:08:16
I could only dream of 27mpg from a 3.2 auto. I once got 30mpg from Cardiff to Oxford, but it was mostly 22ish on average. That was on petrol. LPG is 17-19mpg.

I know tunnie is Miss Daisy, I think Mr Omegaman has just confirmed what I suspected when he said never got GY F1s to let go ;D

My 2.2 DTI saloon averages over a daily run (up and down some big hills) a princely 39.3 (with air-con on) and the best I have seen is on a run up the A12 to Lowestoft when I first reset the computer of......Wait for it...49.1. That was cruising at or around 70 ish. I knew there was a reason I bought a tractor. My old 2.5td estate used to do on the same runs 31 and 43. Which I thought was pretty good at the time.

Post by: YZ250 on 19 May 2014, 09:04:38
Regardless of how hard I try (and that's not very hard  ;D), my 3.2 always settles back to 22 mpg. Yes I can kid myself by resetting the display as I'm doing 70mph on a motorway and see the display hit 30 mpg, but it will always come back down to 22 mpg, or less, when I come off the motorway. If it was used mainly in towns, you'd be looking at around 18-19 mpg tops.  :)

That's your problem :y in fact I would go as far as to say I'm suprised you're getting that much out of it tbh :-\
If you doubled or even tripled your commute, it probably wouldn't use much more fuel... would be better for the car too :y

Seems all the posts are from petrol's, where's all the diesels?

Just to clarify my figures are for averages and the 39+ mpg is for over 500 odd miles locally and its the hills where I live that hurt that figure. The A12 run was reset before we left and was the average mpg shown when we got there, I had only just got it then and was still playing with all the buttons etc. I was mighty impressed with the figures but as usual would always like more. Has anybody had any experience with a remap on the 2.2 Dti? If so does it give more poke and power in the real world ie not advertising speak. Pro's N cons?

I make that about 31 and a bit (cos you never use the whole tank) on a run, not to shabby considering, depends very much on how quick you were going because as soon as you get into the 80's OUCH its gonna hurt. I even notice it on my old wagon.

80!! No, it was a nice steady run only touched  those speeds once or twice. Mostly 60's I seem to remember.
31mpg,is that all?? Blimey, thought It'd have been higher than that, wishful thinking me thinks.

Here is a question for yeh

I know the estates are slower due to the slight increase in weight and the drag off the tailgate.
How much does it affect the mpg ?

I'm asking because my first mig (2.5 manual saloon) would do 27mpg urban and 34 on a run.
All my estates since have never got even close  :(

my new 2000 2.5 estate manual petrol is giving a satisfying 32mg overall each week, which includes 200 miles on the M4 every Friday, plus another 150 miles local running about. The similar car I scrapped in April peformed similarly. I have no idea what my 3.2 manual police special gives, because it has no computer.

Variable, I've run out at 8 miles before, but in another did another 18 miles after the range read 0, and still only got a shade over 73l in...

2.6 CDX, autobox, saloon: 26mpg on average. Once had 30 mpg on a motorway, round town is MUCH worse and I've had 7 mpg accelerating up a hill a few times - the nice one going to Beaconsfield out of Amersham.

Blimey, only 73litres in, they only hold 75!

If that was my 2.2 Dti I would have had a fright as once they run dry on fuel then they are pigs to start again as no self bleed. I could not risk driving around with just a couple of litres in the tank with a crap design like mine. The 2.5td's self bleed so I never worried and the petrol's are the same, run out pour some in and away you go......not with mine.  >:(

Luckily I never had to try it as I never ran out of fuel, never had a problem after changing the fuel filter though I know some people do. I don't fancy trying my luck with the DTI either as I have heard they can be a real B###h. Still looking at the fuel consumption figures on here I am still rather glad I have one....so far....till the pump packs up. :(

I cant remember how many litres I put in but I did brim it ALL the way and was running on fumes when I got home. So tbh I probably got less than 31 cos there must've been a gallon up the filler pipe ;D

My 2.2 auto estate is approximately 25mpg average around town and the best I have ever managed was 35.7mpg on a long motorway trip trying to keep to 70 and driving as carefully as possible.  My old 1995 2.0 auto estate managed over 40mpg on a couple of similar trips before I wrote it off.

Aye, my 2.2DTi Elite lives on in a couple of other cars now, the rest of it is probably cubed and on a boat to China and the 2.2DTi CD Estate going the same way.

2.2 DTi Elite Saloon - 40 MPG - Mainly empty Motorway at silly O'clock on cruise control
2.2 DTi CD Estate - 33 MPG - used by Mrs VXL for a 5 mile commute into town through traffic
3.2 V6 Elite Saloon - 26 MPG - journey as per DTi Elite, 21 MPG when driving it properly off the motorway
2.6 V6 Elite Saloon with G cams - 26.8 MPG - journey as per DTi Elite

Not sure how accurate the CID is in the 2.6 as from full tank to start of red is around 460 whereas the 3.2 is 400.

In comparison to Mrs VXL's Estate, her 1.9 SEAT Alhambra 130 SE does 45MPG without trying, a lot more on a proper run.

Thing about the DTi's is the Torque, OK it's in a narrow band (Hence a manual box) but it's only 10NM less than a 3.2

MPG figures are easily skewed though when you consider the cost differences between the fuels.

Title: Re: Real world MPG
Post by: Magwheels on 21 May 2014, 09:40:45
Yep, mine has already had a pump changed by the previous owner and it had only done about 116k then, what a stupid piece if kit to put in a diesel!

Lets see how long this one lasts, trouble is it's such a nice car.......but I still think my old 95 td was smooooooth compared to the clattery 4 pot.

Yep also agree with the torque, pulls harder than I expected and very useable once you get used to it, if a little peaky, that's why I was looking at a remap to maybe smooth out or extend the torque range a bit (and MPG).

As you say other diesels of the era do more mpg (wife's Golf 1.9pd does 48mpg without just about everywhere) but are usually not as heavy as our wagon's.

Around here petrol only works out about 3% cheaper so I more than make up for that in mpg......Until I factor in the price of another pump when I need one!! :'(

i picked my 3.0 auto up from clacton on sea with just over a quarter tank of petrol, drove it back to margate which is about 133 ish miles, stuck to 70ish with the occasional 'spirited' overtake and averaged 31mpg and the petrol light came on about a hundred yards from my place. pretty good i thought!!

3.0V6 manual, 70mile trip a few weeks ago, 39.2mpg at fairly constant 70mph, 4 up with full boot.

My normal (50/50 urban/trunk road) back and forth to work, I can get it to about 32mpg if I go real easy, usually sits about 27/28 though cos I tend to drive it like I stole it.

27.4mpg over 140 miles today. Mainly twisty roads with about 35 miles dual carriageway. Mixed driving. A/C on all the time, It's running purely on Shell V Power Nitro fuel for the past month or so.

My 3.0l auto estate generally shows about 25mpg average with my  mixed 7 mile commute and running around town. Loaded up on holiday, with 3 people, a bootful of stuff and my bike on the towbar it averaged 28mpg over 1800 French motorway miles, running at at least the speed limit.
Driven gently on the motorway, it happily does 30mpg, and if I can keep the speed down to 60(which we did all the way back from Beaulieu one time) about 34mpg.

I should add that although I don't have a heavy right foot, I do consistently make good progress on all roads.

What am I doing wrong, as these figures seem a bit high?

2.6 auto - 17mpg London stop-start driving, 25mpg mucking about on country roads, 33mpg steady 70 on the motorway.  Subtract one or two with air-con.

But here's one to give you a laugh.  Couple of years back when my thermostat failed stuck open, the temperature would drop off the cold end of the scale at motorway speeds with correspondingly poor mpg .  Looking for a way to reduce air flow over the rad I tried tucking in behind HGVs and the temp did indeed rise to around normal.  But, with speed restricted to 57mph and getting the air tow from the wagon ahead, I could get 45mpg!  The boredom quickly does your head in but definitely the way to go if you're trying to make it to the next filling station on an empty tank.
