it could just be the grade of the fuel. I know with my car which i drive the same no matter Wat that my FE would drop 3-4mpg when i would fill up with Sunoco, but wen i went with the local ran gas station which has better grade fuel and pumps the fuel for you versus the self pump station were it costs the same at both, self pay is normally higher as well. It only makes sense just to go to the pump for you station according to same to sometimes lower price but proven mpg gains onto of it all
