Don't throw a party just yet.

While it is possible you will be getting that kind of mileage, it is HIGHLY unlikely. A single fill is not enough to really check it; too prone to "measurement errors".
You DID pay close attention to where the gas stopped on the filler neck, right? (just barely touching the bottom, hopefully) so you can duplicate that point for the next couple of fills and do an average ??

The difference between filling to the bottom of the neck and trying to cram in as much as possible can be .3-.4 gal. and is enough to throw your calculations WAY off.
