If you empty it to 'eek' a full ten gallons in it, couldn't you have just topped it off.. Either way the gas tank will hold the same amount, its not going to grow just because you emptied it.

Thank you I never thought of that. I have an open sore on my genitals.

A bit surprised it seems to spimle and yet useful.

Maybe the gas pump was miscalibrated. They are cheating you, charging for more gas than was actually put in.

Simple, really: 10.8 gallon tank, with about another gallon and a half of fuel filler pipe. Remember, the gas tank on the Fit is located beneath the front seat.

The Fit automatically calculates your mileage for you. Why do you need to do it manually - do you find that the mileage data you generate is significantly different from the number on the dashboard?

I just had the EXACT same experience in a 2008 Fit - 12.2 gallons. And I don't think Costco is ripping me off on gas.

The fuel tank on a Honda fit is 10.8 gallons for the 2007 and 2008 models, then 10.6 gallons for all model years since. However, like with all fuel tanks for all vehicles, the fuel tank actually holds more than that. The fuel tank must be built to handle its rated capacity and allow for thermal expansion of the fuel (since the fuel is stored underground where in summer it might be under 70°F but dispensed into a fuel tank that might be over 100°F). The emission control system also requires a small amount of empty space in the tank. So, if you drive until the tank is dry or nearly dry, then fill it until the pump stops, it should require about 10.6 gallons but there is some wiggle room. You might get 10.8-11.0 gallons before the pump shuts off. It's poor practice to force more than enough to get you up to the next even dollar into the tank by topping it off. However, if you force-feed the tank until fuel is in the filler neck, this could take 12+ gallons. That's probably a bad idea, though, as you could cause damage to emissions control components by flooding them with fuel. Either stop filling when the pump shuts off, or top it off only enough to get to an even dollar purchase amount.
