Sweetbeet pretty much hit the nail on the head, especially if you can't get a good price.
I'm guessing the large price difference is because you're not getting a deal on the FEH but you can on the regular Escape?
I know three people who have Escapes, and they get 12, 16, and 18 MPGs. This tank, and the last tank, I've been at 33.

(Okay so maybe I'm just bragging, but still...)
