no never risk it, why would you?

i just noticed that if you take out the b in your name it spells

et

that small alien thing

Yes...Deffo.

yep..

There's an episode of topgear where the drove from somewhere in France to Blackpool....
All the cars went at least 30miles over what the computer was telling them, and the Jeg even had fuel for 100 miles left,

So in answer to your question; Yes, i would risk it, you have at least 30 miles left when it tells you ZERO !

You reckon that will be same concept with an 8 year old punto?

Once it says empty do i have 30 mileS?

it depends on the car. in simple terms how good is it. if it was brand new i would say go and risk it, but for an old car no i wouldnt.

Good luck don't rev to hard or brake lots and you should be ok:)

pay a company to toe your car till you reach the nearest cheapest petrol station and fill up there instead

FIGHT!!!!!!........oh hang on....

just drive to the cheaper petrol station as fast as you can so you get there before the fuel runs out, easy.

looooooool great plan!!!

yah you should be more than fine!!! infact id put 10squids that you could drive there and back twice!!!!



(edit: i accept no liability if you try my silly little plan just to earn a tenner, if you want a tenner get to the other thread!! )

Car trip computers are not accurrate at all - you'll easily make it.

I have never known a car that has an accurate fuel guage, one of ours currently says its empty but has at least 50 miles left. I have learnt to judge by average fuel consumption etc, rather than go by the guage.

I agree :thumbsup:

you would probably be able to go their and back no problem

You will be dragging all of the sludge up from the bottom of the tank on an old car, it may well cost you more than you save.

Don't trust it, HAL9000

you will be fine there is always loads left after is says zero

to prove it get yourself a few litres in a petrol can and drive another 30 miles - if you run out you have fuel - if you don't you will know next time you have 30 miles

Not sure about the 8 year old Puntos, but the older ones seem pretty tight when it comes to accuracy. I know this from experience. On the plus side though, when you run out of petrol near the top of a large hill, it's lots of fun turning the car around by hand, then giving it a running start, jumping back into the car, and freewheeling it for a mile to the nearest petrol station. You've just got to watch out for the police, who tend not to take kindly to that sort of thing.

I used to dice with zero all the time in my penniless student days, not once did I run out! Used to have a can of fuel in the boot (courtesy of my Dad's lawnmower stash) but never needed it :-D

lol, cos the fuel is usually taken from the top of the tank right?

He's not back yet, I guess he didn't make it.

id do it too. top gear rocks

No but when there is no fuel left, all that is left is sludge in the bottom, that will get in to the system, clog things up, you then end up with a bill for about £100 or more to clean the system.

No brainer.

i havent managed to do the above yet

I have to laugh at all the replies of 'the guages are not accurate, you will be alright'.

If it is not accurate surely this is more reason not to trust that it will get there.

Only if it was accurate would you be sure you would get there.

£10 means £1 extra, for the sake of running out and spending £5 for a petrol container after the long walk to the station (bet you run out exactly half way between the 2) I know what I would do.

SHE did make it back, although I drove to Tesco and low and behold they had no unleaded so had to drive round the corner to Texaco which cost me just as much as the village one would have:oops:

Perhaps you should support your local village filling station then, incase it is forced into closure due to lack of custom, by the actions of folk like yourself, and you will loose that handy option in the future? :thumbsup:

No. Because they are not entirely accurate the manufacturers make sure they have a lot more in reserve than they are letting on just to cover their own backs if a car said it had 20miles left and it didnt make it 20 miles :thumbsup:

I do but not if im filling up!

Did you not see the Top Gear Episode where Jeremy drove a Jag and it told him he had no fuel left but he did another 40 miles in it and when he got there - they examined the tank and found another 120 miles of fuel still available (computer working fine).

I think there is some held in reserve even with these calculations in place..

I have a Mazda6, i drove to work (12miles) when the computer told me i had 6 miles remaining. I managed to drive to work then back home again. the Computer said 0, yet i managed to travel 18 miles more :P

Why does this sludge not normally go through the engine then seeing as it's at the bottom of the tank where the fuel is taken from?
