Hey gang,

I commute from Gloucestershire to London and thought I'd take it easy yesterday doing a steady 55mph and achieved a fabulous 60mpg. Is this to be expected. Seems a fantastic mpg considering it's a powerful turbo diesel...?

Cheers,

Slatros

The computer is optimistic...to say the least. The only accurate way to measure mpg is to fill your tank, run it for however long, fill it up again and do the sums.

All the best

Have you had her remapped yet? you will have so much fun mpg attempts will be a thing of the past!! Although in average driving since my remap i have definitely had an improvement in mpg.

which remap /what company did you use?

I'm thinking of it for my GT - wondering if clutch etc holds up to the 190bhp Angel tuning advertise?

There are a few reasons all modern cars seem to read slightly on the fast side for the speedo.

Better MPG on the trip computer is a big one. Lower noise at speed is another.

I find computer on GT overstates by 1mpg on 1st click to click fill ups. Have achieved 54mpg with decent fuel and light right foot on round trip to Manchester from Worcester

Angel tuning, the remap result is achieved with clutch in mind. So the power delivery is linear, no spikes. Really use able torque higher up. I like to drive my cars but am careful how and when i bring the power in. Just be sensible. Its transformed my GT, the engine sounds a lot better and seems to be loosening up! sounds a crazy statement, but its true she has just over 80k.

i did a trip to northumberland and back and got averges of 61mpg and just got 60 to wales and back, i am running with a tuning box on though and deffinatly know its doing more mpg with it and if u do a rough calc saying that 3 gallons is 20 that will give u range of 180 miles then the sums add up with what fuel i put in and the miles covered

This is as good as I've ever achieved, a trip earlier on in the year from Kent to Cornwall. I could have done better if I really tried though

Yes the white back-lighting at night is most aesthetically pleasing

Thats what I'm talkin about.

Wow! now that is sweet!! wonder if its possible to change the speedo in my 2004 GT to the later one? does anyone know if its possible?

4.2mpg????lol WTF?

[Coley123]

Is that 4.2mpg? bit on the high side. I get twice that and more!!

 

[ponchoj]

4.2mpg is about right with the V6. :lol:

 

[PAJ]

I don't reckon the trip computer overstates by much - as B4UNOIT says I think it's by around 1mpg at most. I use Fuelly to measure what I'm getting - I typically get around 31.5mpg from my JTS GT when calculating based on miles covered and fuel added, whereas the GT's computer says I'm getting 32.0 mpg. Woeful figures compared to your 60 mpg!

 

[Singularity]

Mines the derv too. :lol: Obviously

I guess you could swap the speedos? Not sure if the dash is different though, get a pic of the old dash and compare.
