You guys missed my point! The gas consumption depends on how you drive. No question about that.

It's about filling up when the gas light comes on, which it should give you the same amount, well relatively. I'm pretty sure that the gas light is accurate. I'm assuming there is some sensors (or something) in the tank that would initiate when the gas level hit a certain point. I'm also assuming that it should comes on when there's about 2 gallons in the tank. The system should be pretty good cause the guys at Honda doesn't want you to get stranded within few miles after the light comes on. So it's safe to assume that the gas light is pretty accurate. So, let's say the gas light comes on with around 2 gallons left in the tank, and given the capacity of the tank(13.6) you should fill up the tank with around 11 gallons and that figure has to be very close each time you hit the pump. So how do you explain the flactuation I'm getting at the pump? up to 3 gallons?!!

The only explaination is ....it's that automatic shut off when you fill up your tank. I think that the tank takes in a different amount each time you fill it up and that's how I end up with a different amount when I fill up. You can argue that, that automatic shut off should be accurate too; gas expands when exposed to heat and might cause some damage if it's overfilled. Let me close on a funny thing happened to me; I filled up with 14.3 gallon !!!! (capacity 13.6) !!!!
