Using the same pump at the same station every time definitely helps, but you'll still have fill variations. Some of it just depends on the fuel tank, how it's shape can change since it's made of a thin-walled material. Also, you can get air pockets in the tank as well--they don't always come out consistantly.

It can be frustrating, but in the end it all comes out in the wash. One tank may look artificially low and another artificially high, but it all averages out.
