For the first time since getting car (20v na) decided to see how many mpg I was getting. Filled to brim to start and then yesterday put in £68.60@ £1.32 a litre. Did 349 miles of which 150 was a run to coast and back and rest my daily commute(5 miles each way ) to work in London

Managed to get 30.51 Mpg which I was pleasantly surprised with

Just wondered how it compares with others

i have no idea what i get. I average about 330 miles out of a full tank. need to refill soon so this time i'll try and work it out. Can i ask how you worked out your mpg as i have no idea how to do the maths...... maybe theres a simple website out there....

That's pretty good stevelondon.

On a mainly motorway run I'd expect 32mpg, less when its mixed driving.

its pretty easy.

Fill up the tank.
reset the 'trip computer'
Drive around for a bit.
Fill up the tank.
Record the amount of fuel that has gone in, and the miles you have done.

You'll then need to convert the litres of fuel total into gallons. Then just divide that by the number of miles you have done.

Well I'm well impressed since mine has been mapped I got 31.2 mpg.

Isle of Skye to Lancaster - 36.5mpg

On a motorway run, up to 38mpg. In town, as low as 25 though rarely averaging less than 32mpg on a tank full.

I get 27-28mpg average on my 20 mile round trip to work and back, i tend to sit in traffic for 10 mins some days.
A trip around Wales i got 34mpg.

That included Flea testing her and me getting back from Bristol at the correct speed limits

Maybe mine was a one off good figure helped by the run to coast
Will see what next one is like

Does mapping improve mpg then?

Always 330-ish to a full tank, so 30mpg-ish, it's always a mix of motorways, town, A roads and stop start traffic. A bit less (maybe 290-300 to a tank) when the weather's nice and the roads are empty (which is rare!).

(edit: That's with a GTEC1 @ 1.2 bar)

Mine recently did 100 miles without using any fuel at all.... although it was on a trailer to Motormech

I managed 27.4mpg on the last tank of fuel, mainly driving to work & back (22 mile round trip)
I'm running on 99ron with a GT28R, fmic, 3" dp etc

Wrong!!!

Divide the total miles by the number of gallons

isnt that what i've said?

ahh you mean the other way around

Well i would hope that when someone tries it my way and gets a result of 0.035MPG or whatever, then they'd try it the other way around

I filled up with £68.60@£1.32 per litre
That's 51.97 litres
There are 4.55 litres to an imperial gallon
So 51.97 divided by 4.55 = 11.44 gallons

I did 349 miles on that tank
So divide miles 349 by fuel used in gallons 11.33

And you get 30.51 mpg

Simples!

Hmm, whilst I agree there's still room for some numpties to make it look otherwise



Perfect

And my first tankful in the VIS reveals:

Filled up with £70.00@£1.34 per litre
That's 52.24 litres
There are 4.55 litres to an imperial gallon
So 52.24 divided by 4.55 = 11.48 gallons

I did 368 miles on that tank
So divide miles 368 by fuel used in gallons 11.48

And you get 32.05 mpg

Not too shabby, mix of motorway and urban. And a fair bit of hoonery (testing the new car of course)!

Bloody accountants

We're the cockroaches of the business world. After the bomb has dropped on a company we'll be the only thing surviving there at the death

Recession, job losses, company closures?

Nah, they'd post here to complain about their terrible fuel economy!

I get about 3 month's to the tankfull.

i thought it was 4.54 ltrs to the gallon
As for my mpg!! Lets just say I must have a fuel leak, at a guess the mid 20's but I will need to fill her up and double check that figure..

Driving style? If you're always giving it the beans on boost that'd explain mid 20's. Hell, if you're on track giving it beans expect single figure MPG's

Best ever was 43mpg (Staffordshire to Newcastle [375 miles] and back on just over half a tank)

Worst was 7.9mpg at Bedford Autodrome

Average is about 30mpg, with 35 easily achievable on a motorway run

I always get about 320 miles to what I think is a tank, but it never takes more than 50 litres to brim it again so would probably do 400 before it actually ran out.

Last time I measured it I did 28mpg on mixed A roads and short journeys with a heavy right foot, which I was pleased with.

My old broom 20v, was fantastic on fuel - nearly 500 miles to a tank, porto 20v with 17"s did around 400-410.

20VT is obviously worse, and made worse at the moment by desperately needing a map, roughly i get 350 tops.

To be honest though, you dont buy a coupe for fuel economy.

Grrr. Want that engine.

Scots Green 20VT 271bhp, used for hooning around - 30.5mpg (422m on a full 63 litre tank)

Moon Grey 20VT6 about 250bhp, used for longer drives - 34.5mpg (478m on full tank)

I keep a petrol log of both - I don't let them get too low though .

My Toyota van (2.3 diesel) has averaged 31.5mpg over 194000 miles - am I not a sad ?! Mind you, the tax man always wants to know......
