You've got a short fill on one freeway trip--don't sweat it. There's so much margin of error here that it's impossible to say what's responsible. It could be any combination of:
-pump error
-tank error from the short fill
-weather: temperature, wind speed and direction (huge source of error just right here)
-traffic
-rate of acceleration/deceleration
People like to complain about the way EPA ratings are determined--but there's a reason it's best to do it on a dyno in a temperature-controlled lab: you remove all these other variables.
