17 / 18 mpg (UK) not driven too much like a hooligan but with use of sport mode and cruise (not at the same time!!) - eldest (19yrs) son gets 21mpg, daughter (15yrs) gets 5mpg (OK I cheated on that 1 'cos that's when she tows a Cambridge roller around a 3 acre field in high ratio) :D

Hi Jeff,

How do you calculate your LPG on LPG? Do you read it on the computer?
I ask because i never seen a car with a better MPG on LPG. Just my 2 cents

I do about 16mpg on average with a very light foot. Although one time I was about to hit 20 and then stop and go traffic ruined it for me :( .

Running average since I bought the car is 13.4 US MPG. Pretty even mix of 75-90 MPH freeway driving and congested city driving.

I'm afraid I'm in the Tasi Devil category (maybe because I grew up on Tassie) - I wouldn't have a clue - my indy mechanic says to drive it like you've stolen it and it's actually not bad advice - they don't like to be mollycoddled these cars - but I don't dare look at the petrol consumption. I've only done 30k kilometres in four years anyway so not a big issue for me.

Cheers

What an interesting post. Not that I didn't know that O2 sensors could help. Now I am motivated to just change them. We have owned our '02 P38 for 14 months and I've never tuned it up. Who knows how long it has gone without a tune-up?

High 15.42 mpg
Low 10.99 mpg
Avg 13.14 mpg.

Mixed highway and city. Heavy foot.

14 UK mpg around the streets of London

21 Uk mpg on a steady run (not exceeding 70mph, its against the law :naughty: )

16 UK mpg average

Thats all with a very light foot and I think above average anticipation of traffic conditions. Blowin me own trumpet I know, but drove a London Bus many moons ago and some say thats the best training you can get, but then again some say its the worst :doh:

All I know looking at those figures and petrol climbing towards £5.00 a gallon again, I must be bloody mad!!
