Fuel Gauge or Range Computer What do you trust?

[JoshE93]

Had my clio just over a week now not been sure wether to trust the range computer or the gauge

Today my Gauge was just slightly above the red line but my range computer said i had about 90 odd miles left but i bottled it and tried finidng a petrol station with some fuel haha

Put a tenners worth in priced at 1.38.9 the gauge was reading between the first and second white line but the range said i had about 230 miles

So just wondering what do you all go by the gauge or the computer

If you'd filled it to the brim, you'd know how much you had left...(50 litres [or whatever it holds] less how much it took to fill it up).

Then, knowing what your likely mpg is...you'll know how far out/accurate it is.

Until you do that, you've only got really random guesswork to go on.

 

[MartinR]

I trust neither and no one

I wait until my range goes below 30miles left aka 'range -----' before I fill up

Even when the fuel light comes on you seem to be able to get 15 / 20miles out of my 172.

my 172 cup was good for near 40miles once the light came on, if I drove it like an old lady.

my puma however, is good for about 10, the light comes on and its like 'GOD-DAMN, NEED TO FILL UP QUICK!'

when the light comes on you have 10 miles easily left
any more is a risk
tbh its not good to run that low as you will drag up the crap from the bottom of the tank etc etc

No you dont

 

[aucky]

Both are close enough imo.

 

[bengtt5]

No you dont

and why do you say that

 

[Jaff.]

Because your pump picks up the fuel from the bottom of the tank anyway. Then before the pump there's a strainer to stop big chunks of crap being sucked up then after the pump there's a fuel filter to stop the small crap from getting through. That's only because we're assuming your fuel tank is like a sewer of foreign matter, which it isn't. How much crap do you think can get through the fuel nozzle at the pumps, then the strainer then the filter?

 

[aucky]

Its not crude oil lol. Petrol is clean.

 

[Duffman_172]

I would like to think that the range computer is accurate but to be honest I buy fuel on a weekly basis and never let it get that low so could not honestly say!

 

[Munson]

The muck at the bottom of the tank myth is a myth.

 

[Junior Bear]

Just put some fairy liquid in the tank, that'll clean it

 

[Brett]

I think they're both reasonably accurate. I've ran Clio's for three years cumulatively and I've never run out of petrol yet.

My computer once said I only had 1litre of fuel left, still manged a few miles. My fuel light comes on later in the 182 than it did in my 1.6 though.

 

[DrR]

I fill mine up, then reset the mile counter, when it gets to 320 miles I know it's time to fill up.

 

[JoshE93]

well at the min i put 20 quid a week in and when the range goes below 100 miles the gauge is around the red line
