What mpg does your car really do?

Just checked the official guidelines on my car which states it should do an average of 56.5 mpg - a bit different from the 38 mpg that it is actually doing

Mercedes A class, 57 plate, usually 29mpg on school run (stop/start all the way there, and back). Nowhere near what was advertised! grrr

52 plate s max 2 litre diesel between 44-45 mpg
52 plate Nissan note petrol 1.4 litre approx 48mpg.
Both driven reasonable speeds, neither racing or crawling.
Good idea to post the true mpg's, rather than the advertised rates. Hth.

51 plate vw estate diesel, very fuel efficient, usually 55-60 mpg. It's why we're reluctant to get a newer car.

1.2 16v Renault Clio (2004) 38 ish - local short journeys, town traffic

57 reg Mazda 6 2.0 TS gets about 40mpg - DH does very little town or city driving in it, which would probably make it less efficient. He still doesn't get the mpg quoted for the model, though. Being a diesel, it needs knocking down into 4th, periodically, on long journeys, to get the revs up, or else it ends up with warning lights flashing.

Renault grand scenic 1.9 diesel 58 plate - 35-40mpg around town with up to late 40s on a motorway journey, have had up to 55 when being super careful and driving at 56mph but very difficult to maintain that.

Sorry, it is a 1.3 engine

Mazda2 (13 plate) - according to the screen, it is doing about 38 mpg although I have only had it a couple of weeks so I guess the 'average' hasn't calculated properly yet.

Not sure what the official guidance is.

I reckon this is pretty good for such a large car.

My 2009 Citroen Berlingo Multispace XTR 1.6l diesel usually gets 45.5mpg according to the computer. I can average this on most tanks of fuel. I've been driving carefully the past week or so and I've currently got it up to 47.8mpg :)

My little seat Ibiza gets a minimum average of 60mpg (if I concentrate I can get over 70). It's the cheapest car to run that I've ever owned. Also road tax being zero at the moment makes it even better.
The Saab estate we've got manages an average if about 28mpg... Not quite what we were told when we bought it

Sorry, 1.9TDi GhiaX.

02 Galaxy. 38-40 mpg on 25 mile A road run, 45+ on motorways. So its computer says. I haven't actually measured the fuel or anything.

I have a VW Touareg. Not sure what its official mpg is but i get about 25mpg on average. Never seen it go above 30. Dont think its way off though. Its a 07 plate.

Toyota Yaris 53 reg 1.3 currently getting 50.1mpg.

Renault grand Scenic ( just got rid of it) 05 reg 1.6 was doing 38.4mpg.

Can't comment on new car yet as it doesn't have the right button and we are still on first tank.
