im sure this has been discussed a million times, so heres one million and one. its difficult to get an accurate reading of mileage with barely a half tank used. the smaller the total mileage you are dividing in to, the easier it is for any variance in the fill to affect your outcome. the way you fill on that particular pump and the peculiar characteristics on that pump can really skew a small numerator (mileage total). i always get a chuckle when someone says "i got 50 mpg on my car. i went 50 miles after filling, then filled, and it took 1 gallon to refill."

while its not good to run your tank near empty too often, it is the best way to get the most accurate mileage reading on a given tank.
