When I went to croft at the weekend I put £75 pounds in to fill the tank and it used over half a tank to get me there , and I wasn't hooning it as it was the 1st trip out since it's been back on the road , then I managed to get back to Lancaster services put another £30 in to get us home , there is a little left just under a quarter , anyone else think that seems a bit too much ?

Yes. My S1 used a full tank to do 230 mile.

God knows why

Cosworth Lad

years ago went to essex 400 mile round trip £80 quid then anther £30 to get back but then had it dynod on the same fuel greens aswell.

With Petrol @ £5.85 a gallon thats 18.4mpg.

You need that set up.

I was getting upto 32mpg out of the 4i on a run, running 83lb injectors.

How do you work out mpg people.

cossynut2

At what speed ? I also have the 83lb injectors and think its good to get 25mpg.
If you are really pressing on you can almost see the fuel gauge going down!!

Number of miles driven / number of gallons used
100 miles driven / 3 gallons used = 33.3 mpg

cossie4i+

iTrader: (15)

Steady drive @ 70-75mph

No booting at all

And yes when I boot it you can watch the petrol gauge go down

Steve

iTrader: (2)

Well I paid £1.34 a litre so bit less mpg

If you're worrying about petrol usages etc you've got the wrong car sell the car and buy a 1.1 Micra, simple.

Has it been mapped Lee?

hitchwest

iTrader: (2)

I know having a cosworth isn't about fuel economy I'm just thinking it seems a little expensive , and it was mapped by Karl in 2007 and not been touched since

Staffi

iTrader: (1)

Thought you were having MDS Closed loop etc Lee ?

That wasn't a dig directed at you specifically bud, I've seen threads like it before and i just don't get it! enjoy them and hammer them sod the fuel gauge. Lol

hitchwest

iTrader: (2)

It's the next plan , well there's a list of bits need to sort 1st really

Staffi

iTrader: (1)

Lee,

You still on Greys?

Jay,

iTrader: (4)

I just fill it up and hit the loud pedal a 240 mile was about £50 and that was a steady 80 to 140 ish

Staffi

iTrader: (1)

Amen to that Jay

Closed loop ftw

Not on greys yet

fatboy billy

I only get 200 miles to a tank mixed driving long runs and short trips although mine needs a setup badly

Paul_RS

iTrader: (4)

On the motorway with a few blasts I get over 300 miles to a tank. I reckon i could get near 350 if i was very sensible. T34.63 on 55lbs with a MSD live map (I have a shorter 5th gear as well)

i've got a spreadsheet for my fuel usage for both cars

along the top it says:

date - mileage - distance covered - fuel used (litres) - fuel used (gallons) - cost per litre - litres/mile - total cost - mpg

the date is obvious, when you fill up
the mileage is the total mileage on the odometer
the program then works out the miles covered since the last fill up
then i input how many litres of fuel i put in
the program then coverts this to gallons
then i input the cost per litre of fuel
and by using maths, the program then spits out how much it's cost me per mile and how much the mpg was
the last 3 fill ups on the mondeo worked out to be 16.71 mpg, 22.68mpg and 20.33 mpg
only started to do the fiesta this past week and that was 21.07 mpg (but it's all stop start and 1 mile there and 1 mile back type of stuff)

over the course of a few months you should be able to see a decent pattern forming, and if you start to add in where you filled up and what you put into it, it may also show you which fuel is best for economy too

Rod-Tarry

Im going to mix water with the Petrol to make it go a bit further & then put a throttle stop to allow only 6mm of travel. Take the engine back to standard & then take off the Turbo. All these years with a Cossie & i didnt realise fuel ecconomy was the main aim. Im not sure towing mine with my Pug 107 will improve things but im going to try that next. Its got me thinking I may be best selling it & buying one of those Prias things.

Jay,

iTrader: (4)

In my opinion if the afr's are correct the car will do what it does mpg wise and when a cossie spends most of the time at wot who gives a fuck

Rod-Tarry

I agree Jay if a Cossie aint using loads of juice your not enjoying it.
Many years back we did a mpg check after a day of Topspeed testing at Brunters it was 4mpg on race fuel. These cars were inefficient piles of junk back in the days so dont expect too much now .

Jay,

iTrader: (4)

This is it even when i had time away from cossies the skyline ,evo st were never economical but never really gave it a thought until I got the dc2 type r that was like running a lawn mower went from using about £80 a week to £20

I think some people aren't getting what this original thread was about I was after what other people were getting out of a tank full , cos it's the 1st time since 2011 that my car has had a long run , and was trying to work out weather or not it was over fueling, I didn't buy my saff in 2006 to worry about fuel economy , maybe it's just the shock with how much the price of fuel has gone up now , and my car is a stage 1 gunship by nms so I'm not running massive boost

Rod-Tarry

I think we all got what it was about its just PF banter & can be ignored .
Some people check fuel consumption others dont. I have a full log of all money spent since October 1963. it stands at £302981 as of the 1st of the month. Its a completely useless figure cos when i started fuel was 4.6p a litre now its £1.30 . However my wage was £196 a year back then another completely useless fact. Get your car checked out & then forget mpg it dont go with the word Cossie. We have people on here boasting about how many mpg they get from there modded Cossie IMO they are complete Tonka Toys .

ajamesc

The day I worry about mpg in my cossie or have it mapped with mpg in mind is the day I sell it and by 1.9td passat lol

caprixpack

On a run to central france I got 450 miles to a tank in my 924 I'm getting roughly between 30 to 35 mpg not bad for a 30 year old

Fil

on a decent run,a and a bit off around town driving, the cosy does mid 20s mpg

t34.63 @ 30psi, 380ish bhp, so would say yours should be a bit better than what your getting

Ive just looked on google and looked at the distance from where I live to santa pod. Its 191 mile. Ive done from my house to pod on half a tank.

Ive never worried about mpg on my cossie. I bought the car to drive and enjoy.

Im sure it cost me about 115 quid to get to and from the pod.

My next plans are to get it remapped on greys , and maybe go for closed loop

hitchwest

iTrader: (2)

Did the shorter 5 th make a difference mate , I've been thinking about doing something to the gearbox as when travelling at 70 / 75 in 5th mines on boost only slightly but that will prob why mine uses so much fuel

Jay,

iTrader: (4)

My sons car is a t3 hybrid on greens mate its doing around 300 ish to a tank motorway driving you should be getting 25 ish on a run so like i said check sensors check tps and fuel pressure

cossynut2

Agree with you 100%, I personally dont believe some of the claims of how many MPG their cossies are doing. They must drive them off boost at 50mph!! I have had my 2wd Sapphire for 19 years and enjoy DRIVING it, if I wanted a car that did loads of MPG I would not have bought it and modified it in the first place!!
I cannot believe this thread has turned into a "my cossie does more MPG than yours"

Jay,

iTrader: (4)

But your missing the point if the car is using more fuel than it should do at that stage of tune its liable to bore wash

hitchwest

That's what I have been thinking jay
