What mpg does your car really do?

91 replies

AlexMumsnetCars · 10/04/2013 15:17

What Car? has revealed that more than 95% of cars it tested failed to achieve their official fuel economy (click here for the full story in Mumsnet Cars). So what mpg figures do your cars manage in reality? Include your car's model, engine, trim and age if you can.

Citroen C3 Picasso '59 plate 1.6 Diesel 48 mpg average in a rural-ish location. No idea what it's meant to be.

MrsHiddleston · 10/04/2013 19:37

Aaahhh right so some people have cars that actually show this information. I see. I really wouldn't even hazard a guess. I'm off to google!

havingamoment · 10/04/2013 19:24

About 15-20mpg. Advertised at arnd 30. One of the reasons I'm trading it in....

Chaoscarriesonagain · 10/04/2013 19:19

Officially 34mpg, actual ...19mpg ... On motorway !!!

LadyMountbatten · 10/04/2013 19:12

( plus i have NO idea re mpg - who cares?!)

BackforGood · 10/04/2013 19:11

Thing is lljkk - I don't want to know how much it costs. I have to do the journey(s) anyway, and am horrified by the cost of fuel, so I really don't want to keep being reminded of what it costs to do stuff I feel is usually essential, or at least important. Wink

JollyPurpleGiant · 10/04/2013 19:11

Yes, my car's computer calculates it. I reset it every fuel refill so I can keep an eye on it :)

As I said already, my mpg is around the 45 mark most of the time and I've got it up to neatly 48 at the moment.

Here are the published figures:

Urban Fuel 45.6 mpg
Extra Urban 58.9 mpg
Combined 53.3 mpg

I don't get anywhere near the Extra Urban numbers even though I mainly drive rurally. The town numbers are not far off though.

LadyMountbatten · 10/04/2013 19:10

i read this as what mpg does my CAT really do, a bit disappointed its cars tbh

ceebeegeebies · 10/04/2013 19:06

Yes mine tells me on my dashboard otherwise I wouldn't have a clue Wink

lljkk · 10/04/2013 19:05

I thought it was normal to keep track, lol.
How else can you start to figure out how much a journey costs?
I would keep track anyway (background in cost benefit analysis).

BackforGood · 10/04/2013 19:03

That's what I was thinking MrsH - but I think some newer cars have this come up in a display on the dashboard.

MrsHiddleston · 10/04/2013 18:56

I have absolutely no idea... Blush I'm amazed people know this fact about their cars.

CMOTDibbler · 10/04/2013 18:56

Mercedes A class 2l diesel auto, 47.8 overall, and I do tend to thrash it a bit. On long motorway journeys I get over 50

lljkk · 10/04/2013 18:55

In a way that's reassuing to hear, Clara. We are right eco-freak drivers so I am extra surprised at the mileage. At least we still get benefit of £30 road tax and ability to park almost anywhere.

usuallyfoundinthefastlane · 10/04/2013 18:52

Seat Leon 2.0 petrol. Latest reading was 24.4 mpg, 10 less than published figures, was mostly on motorway, not good but my driving style probably not help!

trashcansinatra · 10/04/2013 18:46

Jeep Compass 2.2 Diesel. Computer says about 37mpg (not sure if that's US gallons or UK) but on long journeys (without caravan!) can get just over 40.

Fiat 500C 1.2 petrol. Mostly short journeys and about 48mpg. Well short of the promised 63, but still really good.

My DN used to work in the motor trade and she claims every car does about 10mpg until the engine is properly warm, so if you want a real reading, reset the computer when it's warm.

ClaraOswinOswald · 10/04/2013 18:32

Same as lljkk but my car is a 2010 model. Not as good as I'd hoped either.

monkeyfacegrace · 10/04/2013 18:31

Dodge Journey 19
10 plate 2.0l CRD does me around 45mpg. Computer shows 38ish, but thats American gallons so I think Im right in adding 20%....

Husbands Audi R8 does 13mpg on a good day Hmm

SimoneDeBeaver · 10/04/2013 18:24

55 plate Volvo XC70 diesel automatic, 40mpg

Costypop · 10/04/2013 18:20

Sokda Fabia green line estate on short trips around 68mpg longer ones its been running at 84mpg and there is no tax!

lljkk · 10/04/2013 18:10

Petrol 2011 Fiat 500 and 49mpBg on avg. Far below published figures. Must admit I am surprised, our other cars (older diesels) beat published figures by similar margin.
If I get new job I will do about 15k miles per yr; damn, wish I had bought diesel Fiat now.

SweepTheHalls · 10/04/2013 18:09

Renault Grand Modus, 58 plate, 1.4l engine, 51 mpg

chickydoo · 10/04/2013 18:05

Freelander 2012
Diesel 35mpg

Jins · 10/04/2013 18:02

Mini Cooper - official figure is 52.3 and I'm getting 42. I do a lot of short journeys round town though

fengirl1 · 10/04/2013 17:56

Cmax 1.6 diesel does around 50 mpg - and road tax only £30.
