Mpg.. What do you get

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....

steve

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......

Bang on the nail for a vis Dan....used to get 32mpg no matter what....the turbo manages 29 - 31 running a gtec-1 so pretty good really.

Jon

on a full tank in the 20vt i get about 350ish miles if i'm driving normally.

if i go out for a nice long "enthusiastic" drive one evening i can kill a tank in about 250 miles lol.

i also have a old 1.6 n reg rover i brought just to run to work and back in, however that thing seems to use the same sort of petrol that the coupe does!?!?

I never get more than 220-250 miles from a full tank.

Costs me £75 to fill up and I do most of my daily driving through London.

Thank God I don't have to pay that horrendous fuel bill.

On half a tank of V Power I get about 100 miles (stop start driving, mainly off boost).

Well usually get 32 mpg on a motorway run. About 30 mpg on my work run @ 19 miles each way during the week and a little town driving on weekends. Lots of town snarl I'm down to 28 mpg or so. What I used to find was 250 miles to half tank reading with light on about 330 miles but good til 355 miles.
I recently got new tyres.... Bridgestone Turanzas and I think they have dropped the mpg a good bit!!
Car is a standard LE.

Alfex
Not bad mpg

My gauge is same. Takes ages to get down to half tank then goes down a lot faster

How much is fuel there in Ireland ?

Fuel in Ireland is between €1.42 - €1.44 (£1.22) a litre and constantly rising :-( the government well if you could call it that put a 5 cents/litre carbon tax on again. The amount of duty/taxes/levies is just a joke. Car pooling or a diesel might be required in the not too distant future :-(

The Alfa 2.4jtd did 38 to 42 mpg in it's day.

Still cheaper than UK
£1.28 to £1.32 here in London

though I guess with your debt problems (country not yours!) may well see increases in Fuel

I chart my mpg at fuelly.com

http://www.fuelly.com/driver/minimetaller/coupe-20vt

It's usually a mix of motorway and town with a bit of traffic... 29ish mpg average. My old NA did better, about 32mpg average. Going to get a re-map soon I hope.

James

Does a remap make much difference to mpg then ?
I always thought that was more about extra power etc. Which in my mind i would equate with lower mpg...

Remapping is not all about increasing headline bhp figures, improvements to MPG are also to be had amongst the other benefits.

I will, however, leave this to be explained/finished properly by one of the mapping gurus on here.

Nudge nudge Flea, free advertising opportunity

To the best of my knowledge (probably not much), it would depend on what it is mapped for. If mapped for economy then it would use less fuel than if mapped for power etc. I don't want to show up my ignorance so I expect someone else has a better explanation

James

My understanding is that mapping is basically about making an engine run more efficiently for the purpose the driver needs. How people use that additional efficency is up to them.

You can use the extra power to go faster or you can go at the same speed using smaller throttle openings, thus greater fuel economy.

32mpg

Bladdy 'ell! I've been avoiding doing the maths, but I've just worked out 18.5 mpg and 18.26 mpg for the last two fill ups. That's rush hour stop-start mostly, about 16 miles round trip per day.

Time to get that thermostat fixed!

MikeH
Quite scary when you work it out!

I have No trips planned for next few weeks so I'll be doing just commuting in london which will give next fill up a low mpg I'm sure

Average here seems to be around 30ish for combined which isn't too bad ..

Summary? Lots of smiles per litre !!!

I get around 350/375 to a tankful,mixture of motorway and town driving!

30mpg seems awesomely good for a turbo, especially the mid 30's !!! I'd always thought 25 was about normal??

My N/A used to get around 32-35 depending on the right foot.

The fuel economy does influence my decision on which Coupe to buy, as I'll be commuting. 35 mpg is reasonable for a 2 litre petrol car, especially as it is cheaper than diesel these days. I expect though that my insurance quote could be a little higher for a 20vt !

Don't you have to drive like a granny to get that mpg?

Turbo models are only a few mpg less than the N/A, not that much.

A car that won't do 30mpg is broken. Or the driver has a lead foot.

Turbos are worse in town stop/start driving than NAs, but usually better on the longer run.

whatever it is,its better than my old e36 320 auto!nicer to drive too,must be in the mid 30s (i drive slowly to work and back,light throttle,only brake when necessary)

I got 64 mpg on the drive home in my new car. The only downside is that it's a shabby old Rover

NO you don't neeed to drive like a granny. However if your thermostat is broken (about the most common coupe problem) then 30mpg will be a struggle.

Just filled up again (costing £75.77 which is outrageous)after doing only commuting to and from work in london - some 6 miles each way in stop start traffic

Knew would be bad and it was - a mere 21mpg :-(

need to get out and give the car a good run soon.

I am greatly offended by this thread!!

Fast car and MPG..thats abhorrent talk and should be shunned!!

Hmmm


well go on then..



The forged engine gives my around 330+ miles per tank..happy? heck yes.

Well I did a long motorway stint and got 34 mpg, I was well chuffed. I wonder does my car reset sometimes... As mpg has increased to about 30-32 mpg, but less town driving.
Lead foot.... Titanium perhaps in an LE ;-)

19-35mpg.
