Fuel gauges are and always have been just an indicator, they are not reliable and not representative of whats in the tank. Mine stays are near full for a long time then suddenly jumps down to 3/4, then it stays on half before jumping down to near empty. Dont worry about it, it's normal. |

Out of all the cars I have owned, 40 plus, the fuel gauge has never been this far out, in fact most have read lower not higher.

I see where you are coming from, but unless your on your last legs with fuel, I cant see it makes too much difference. The fuel is juggling about in the tank, going round corners, braking. And I think the electronic read out on the dash is just there for amusement more than anything else. It's definately not an accurate and you have to laugh when people start quoting mpg etc. based on it. Same as the temperature read out. Two LR's, parked same spot, two different read outs. You could explain this away by saying it's where the sensor is located, but again, it's only there for a laugh. |

I've worked out that the gauge doesn't just tell you how much fuel is in the car, but tends to react to the distance the car feels you can travel as well. So if you've been especially economical, then you'll be able to travel farther on little fuel, so the gauge reads slightly higher.

The current brochure quotes "useable fueltank capacity" as 68 litres.

The low fuel warning light comes up on mine and the information screen displays 40 miles left and it is only halfway between empty and a quarter of a tank. p****d off with a Digital Keyboard Warrior |

I wouldn't usually run the tank much below a quarter full anyway, but it would be nice to have an accurate indicator of how much fuel is in the tank. Andyfr |
