Full To Dry
I always calibrate the gauge of a new car by running it dry and then filling it in stages while photographing the gauge. When the Fit runs out of gas it is game over, no chance to wiggle the steering wheel and go another km (kilometer about .6 of a mile), pull over while you have some speed left or you will be in trouble in the middle of the road ! The tank will take a maximum of 50 liters ( about 13 US gallons) before overflowing. You cannot do that at a gas station because it takes too much time to get all the air out. It is not necessarily a good practice as you may screw up the system by submerging the air evacuation tube. I have filled it to overflow at least twice and have not yet observed any problem. From my experience there is at least 5 liters (1 gal) of space left after you make the nozzle shut off by itself twice. I have managed over 700 kms (+/- 435 miles) on a tank without running dry. From my observations there is at least 200 kms (125 miles) left in the tank when the light comes on. That corresponds to about 10 litres or 2.5 US gal. Please note that my numbers are associated with highway driving at 65 - 75 mph (120 kph). If you want maximum gas mileage keep the rev counter below 2750 and never have any fun hearing the engine at 4500 !
Not sure about those numbers because that hasn't been my experience in the version sold in the US. However, I have experienced an empty tank ... and there is no wiggle room. When I first got my 2008 Fit, with no comprehension of how far it will go after the gas light comes on, I ran out of gas. It goes quite far after the light comes on but when it is empty, the engine just shuts off ... it doesn't hesitate, stop/start or anything ... it just shuts off. When that happens, just coast to the side of the road or you will be pushing your car to the side of the road ... not fun in rush hour traffic.
It is now +/- 2 years since I wrote the above note. I have run it down to super empty many times and have not run dry. I stand by the max cap of 50 litres and at least 100 kms after the light comes on as long as it is not stop and go driving.
