I've put in 65 liters once when the light wasn't even on for that long (well at least I didn't think it would be THAT empty). But the behaviour has always been the same in the 7 years I had it

I think the light is always correct, but the gauge may not be. Doesn't matter really. Maybe I have lighter fuel.

???

Fake! The original is 'Ronson'. I remember that brand very well. I once filled a lighter and when testing it burned off my eyebrows.

Although I've not run out while going along, the current Coupé (had it over four years, can't call it new anymore!) does have a habit when the fuel light is on of being fine when parking it and then refusing to start again without at least a whole fuel can poured into it, done that a couple of times...
Old Coupé used to go a scary amount of miles with the light on, can't tell at all with this one so now have to fill up as soon as I can when I see the light.

my old coupe guage never worked in the 4 yers of owning it, I found out on the way home from buying it, the guage read 3/4 full but i came to a spluttery hault, I must of run out 5 times in the first couple of months whilst i got used to the level at which it really was empty.

oddly, it would fill to the brim, the guage would read full but then "very slowly" empty to (just above) the 3/4 mark before coming to a spluttery stop.

on very very very odd occasions the guage would drop to the correct level, im talking like once a year.

who needed a light anyway, lol.

My gauge always drops really fast but when the fuel light comes on it will only take about 47 litres at that point, which is a nice surprise in the end. A fuel cam would be useful like they had on that top gear challenge...

Ahh, just fill it every four hundred miles whether it needs it or not. No problem!

I got in my car this morning and it said 26 miles left, I then drove down my drive and onto the road and it said 1 mile left!

Still I guess thats the problem with a 25 mile drive!!

Seriously though, I took it to the petrol station and proceeded to put 54.5 litres in a 55 litre tank, and i was thinking the computer must be up the creek and was going to drive to work.
