12.2 + Gallon Fit Tank
I almost always run my '08 Fit to below E, so that I can eek a full 10 gallons into it. Makes it easier to figure mileage. Well, two days ago I was able to put 12.2 gallons of fuel in. I could have done a little more, but decided to stop there. So what is it with Honda claiming the Fit has a 10.8 gallon tank??? Ken

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.
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.
