Ara, did you let the pump shut off or did you fill it till you could see fuel? For me there is anywheres from 2-3 gal of difference. More if it is a very fast flowing pump. Without that method, how will you find out how much fuel you put in? Sure, you have the distance travelled but your fuel consumption is not going to be a constant. I have got close to tank capacity using the fill to the neck method. How are your tire pressures?
