9.5mpg WTF!!!

[Hurdy]

Okay, let me explain...las tweek I topped up the car and reset the trip to zero. Today I have topped it back up and (unless my calculations are wrong) I've just had an average of 9.5mpg

Normally I do not check mpg, but I thought I'd do another "round my local" check. Now I admit that I live next to countryside, with sweeping bends, steep hills etc and my right foot does like to feel the carpet , but an average of 9.5 mpg seems almost unnatainably low

74.1 miles on the trip.
35.49ltrs of super at 109.9 pence per litre
4.54 litres per gallon = 7.82 gallons
74.1miles/7.82 = 9.47 mpg

Or to put it another way 53p a mile

Has anyone else had fuel consumption like this?

Running my car in just now so can't really give a 'flying' mpg but just now my average is 31 mpg and the other night coming home from work (30 mile journey) I got to 37.5 mpg which I was very pleased about even if it did feel like I was driving like an OAP

Hurdy, I got mine down to 16 mpg during my track day at Castle Combe and I was going for it!

Think something must be amiss to be getting only 9mpg!!

You've either got a minor computer glitch (operator error ) or someone fitted the long range "Paris Dakar" fuel tanks between fill ups without you knowing.

Lets go with the computer glitch.

tbh i know the feeling
i would get it looked at
mine's comes in at 18 mpg around town
but the mpg gauge that changes when you're driving flickers around too much IMO (even showing 70-80mpg)!!!
taking it in tomorrow.........

I'm hoping it's a computer glitch. Still can't get my head around it. I may as well get a Hummer with that mpg

you sure you havent 'lost' some fuel by short filling the first time (thinking it was full) then putting more in later?
Its over a pretty short distance too , so maybe not a reliable guess lol

If its really 10 mpg then you must have the V8 edition golf 

320 miles done so far @ 23.7 MPG average running in!

Tank definitely registered as full with the cut-out and with the guage inside

Anyway, I'm giving it another go this week, but I'm off to the MPH/classic car show this weekend and so should get a lot better mileage on a run.

Johno's 'short fill' theory would be reasonable were it not for your gauge showing full when you set off. 9.5 mpg would be just about impossible to achieve however much you've been 'doorhandling' so we'll go back to operator error or 'Bart Simpson' mathematic underachievement.

I'm showing 30.5mpg over 3600 miles but occasionally I can get it to show 180mpg on the instantaneous readout.

  Which is nice.

i get 19mpg around town and 23mpg on the motorway sat at 80mph, ive been tempted to take it in but they will just put it down to the remap  (smiles per gallon)

oh yea and i went to bp station in lancaster the other day 1.15.9 per liter!!!! WTF
