I'm almost on "E" and have the tripometer set. I'll see what this tank gets. This tank will be almost all city driving also so I don't expect it to be that great. If it's over 10mpg I'll be happy and it's looking like it will be. I'm right at 250 miles on the tank and I've yet to put over 25 gallons in the thing, even when the computer said I have "0 miles until empty".

Funny though, when I first filled it up, it said I had 354 miles until empty. I aint gonna make it to 300 miles, that's for sure.

The dash was saying I was up around 13mpg average. That was after two tanks of interstate driving bringing it home. That's gone down to 12mpg with this tank. Don't think it's super accurate though.
