Strage think was mark SAME SORT OF SPEC did the same miles as me yeaterday same route
he only FILLS up NOT £10 HERE AND THERE
so do i normaly
but with the DIESEL MISTAKE i keeped the tank low
And REFILLED THE PETROL AS FOLLOWS
I PUT £15 ON FRI
£15 REDING SERVICE FROM THE CAN
£16 AT COOMBE =£46

THEN


When we got to staines he put in £54 i put in £56 WTF almost the same spec

Cant work it out He left full refilled at stains did 5 laps
COst £54
but cost me £112

And £30 fine for my number plate £10 for it to be made

 

Surely.....

15+15 = 30

30+16 = 46


NOT 56....

 

The specs cant be the same....

.... or your car has a fault

.... or it could just be your use of constant acceleration blips that drink fuel.

.... or the fact you dont have closed loop ?????

.....or your 20 stone heavier than the other driver (this is a joke BTW)




Could be any or all of the above !

 

I'm afraid I can't understand a word you typed...

Something about fuel consumption though? Was it bad?


It is a cossie after all?

 

Yes still double what mark did

 

What was up with the number plate?

 

thats what i mean dave FFS

 

On top of that are you sunburnt? lol

 

No diesel yes

 

I did a 400 mile round trip to coombe in my 500 yesterday running over 400bhp , i used 1 full tank ,and that was with parade laps to

 

soz dave no smell

 

Thats 33.333333 to the gallon....


That dont seem right on a 400bhp motor.... Best I ever got on my 500 was 260 to a tank and that was Stage III

In fact I've never owned a cosworth, standard or modded that would return 400 miles to a tank

 

looks like a few people got done with numberplates at the way from/to coombe

 

My mate everton with a 550 brake ex-hill climb 3dr put £20 in every 2 stations on the way to southend from medway kent

 

£46 on the way there, £56 on the way back i think is what he means
so he's done twice the fuel the other guys done, on basicly the same spec engines and, other than one guy going with a full tank there and back and him topping up there was no other difference

 

well done think i did £10 more than him in if you work it out correctly !!

 

Now this is strange

I have 2 500"s ,, the black one is pushing 340 /350 on 4 greens

,,,,,,,,,,,,,,,,,,,,,,,,The white one is pushing 430 /440 on greys

I took them both to brunters for the photo shoot and used 3 quaters of a tank in the white one and over a tank in the black one

How does that work then ,, the bigger HP car on bigger injectors uses less fuel and we sat together on the motorway

They both have the same ECU , neither on close loop etc

 

it might be the motorway thing
i reckon that the lower pwoered cars will do less motorway miles as they are going to be more "driveable" whereas the bigger powered cars will be set up for big power top end and so they'll sacrifice a bit of fuelin bottom end

i think there might also be a fueling issue if you have all 8 injectors opening up when you plant it as opposed to just 4 for normal driving

or i might be talking bollocks

 

who knows paul maybe i should just put 8 x 1000cc ones might get the 400 mile tank
mind you stage 3 A1RS chip saff did 300 miles to a tank as it was before that on blue standard did 220

 

I done 190 miles and used 28 Litres in the sapph.

Maestro on track was doing about £8.00 to 11 laps, bloody carbs

Spent about £50 on the maestro on track

 

Car looked mega on the PF stand Jase

I did Combe & back on one FULL tank & thats with my Closed Loop not working....think you've got a slight problem there mate

 

My MR2 liverpool - glasgow 158bhp uses just over half a tank of fuel at 80ish mph on the motorway...

Pug 206 1.4 Hire car liverpool - glasgow 85bhp uses a full tank at 80ish mph on the motorway.......


I honestly thought the 1.4 would be better on fuel....


To make it worse it's a really shit car, and had the most UNCOMFORTABLE seats in history.... I was ready to burn it after 2 trips up the motorway, and was soooooo glad to get back in the toyota

 

People who quote x miles to a tank piss me off

If you are going to look at mpg, you have to do it properly!

 

You xsay do it proper explain

 

Small engined cars are under more strain at higher speeds.

 

fill to the brim
drive a bit
fill to the brim
how much feul you put in divided y the iles you've done = economy (or lack of in some cases)

only works when you fill to the brim mind, as everything else is variable depending on teh fuel gauge/temprature/etc
diseasals are worse because they froth up more the faster you put the fuel in as well as how hot it is outside, you can get more in the tank on a cold day than you can on a hot day

 

What he said, but the longer you drive for before filling up again, the better, as it averages out.

 

you sound like my mate dervman

ok, he was anal about his consuption but he did get some exactly exact resluts from his findings, even going so far as running with air con on/off and different temps in and outside the engine bay, ambient temps, inclination of the roads, etc etc

 

Fook that

Doing it over as far as possible just gives a more realistic figure as to what you will get long term, as long as the driving is similar to what you'll normally do.
