Hi, mine's a diesel, so a little different. It's also hard to tell with these cars when they are completely full...at the pump it always seems possible to puta bit more fuel in until it's pouring out of the top! I've never pushed mine until completely empty, but I would guess you've got about a gallon left once the yellow light comes on. The furthest I've drivenis about 45 miles with the light on (which comes on at the same point as yours), but that was at 55 mph on the motorway (and it's a diesel). I wouldn't do that too often as you don't want to pull up any crud into the fuelpipes from the bottom of the tank.

Not sure on the numbers for the petrol Rio, but I doubt you'll get 44 mpg in urban use. The 1.5 diesel gives 46 round town by Kia figures, not real life numbers. My guess for the petrol would be about 30 to 35 around town, going up to a bit more than 40 mpg on the motorway.

Don't forget there's probably a "dead volume" in the tank of one or two litres you won't be able to use...

thanks guys useful responses.

if i could just ask two more question will the light that comes on flicker or will any sort of alarm/warning come on to let me know its nearly empty and
once the needle gets to the E will the needle go flat to the bottom left hand side to indicate that is empty, not that im planning on letting it reach that far or stay at the right hand side of the E

hope my questions make sense.

thanks again.

I don't know if it flickers...probably not. I have noticed that the needle drops very quickly once it hits the empty zone and it can go below the empty mark, but probably not a good experiment to find out what it does after that!
