Would you get better MPG's if you only fill your car up to the 1/4 mark?
This may be a crazy way of thinking...but would you get better MPG's by say only filling up only to 1/4 due to weight?
A gallon of gas weight 6 lbs...So my tank is 16 gallons..if i only filled up to 6 gallons...i would be saving what 60 lbs..is that something that even would matter...i know weight matters in MPG's, HP ect...but is 60 lbs really anything?
Of course it would suck filling up everyday but i am just wondering if you did this for say 2 months..would you notice anything

yes you would get better gas mileage but I think the difference would be sooo small that you might not notice....ex. extra mile or two per tank
better thing to do is to drive smoother and not go more the 50% throttle....I did that and got an extra 50 miles out of my tank!!

When they figure a car's MPGs before it hits the showroom..do they figure that with a full tank of gas?

I've personally gotten 415 miles on one tank driving from PHX to SD.. Could have gotten more but didn't want to risk it.. ~~ That was with mashing it in 3rd to the end of 4th 3 times on the highway when the light came on.
In pure city driving I've gotten 380, again, could have gone more but didnt want to risk it- This was HARD. I was accelerating very very slowly and didn't go over 2000 rpms except for once accidentally.

The difference would be negligible; however, if one was OCD about it, it would require looking at various variables:
- the more fuel, the less evaporation-- in general: BUT--
- the more fuel, the more gas it takes to accelerate the weight (Newton's 2nd Law of Motion), so in town a 1/4 tank would be more efficient
- once you reach your speed, Newton's 1st law of motion kicks in (object in motion tends to stay in motion...), so a full tank would be most efficient if there are not frequent stops
This an extremely abbreviated argument, others who know much more about this than me can tease it out better.
