Bingo!
roycehof got it!
MPG is dependent upon a lot of thing:
driving habits, speed, terrain, and how reproducibly you fill your tank.
I fill mine all the way to to the top of the filled tube every time!
200K miles and doesn't leak yet!
At this rate, even if it started leaking tomorrow I wouldn't attribute it to filling the tank up to the top of the fill tube.
As far as weight, yes, lighter is better, but the difference between a full tank and a half full tank MPG wise is easy offset by driving habits, speed, traffic, etc!
Now if your talking a couple hundred pounds we might be talking a measurable difference!
