If I managed to get 11.3 gallons into a 10.8 gallon tank (plus fuel lines) I'd be suspicious that the gas station is cheating its customers. Suggest you put 'one gallon' from the same pump into a one gallon container and find out!

 

Filling past the 1st click off is bad for the charcoal breather deal. It will trash the charcoal when it saturates it. Got this from my race buddy that's a Master Honda mech in a dealership. It's not worth it.

In theory running with a lower fuel tank will provide better millage. A full Fir tank weights 66 lbs.

 

Hmmm 11.3 in a 10.8 gallon? But that is impressive pulling 400+ for a tank. I would never try that stunt you did though.

 

I could see there being another half gallon in the line feasibly.

I could of made it to 400 today, but did not think it was worth riding around the block at my gas station.

I went 397.3 miles and added 10.115 gal

I drove 30 more miles after the E light came on a 365

I have 900 miles on my Fit now and hope to crack 400 and 40 next tank
