take note din to deduct yung additional weight ng glass bottle ng 1 liter coke when you imagine the 20 pcs, which might also be substantial.
for me, it makes more sense to fill my tank kasi it reduces the number of trips i have to make to the gas station. also, totoo na pag bukas ka ng bukas ng gas cap, sisingawan ka lang ng evap gas. also, a full tank does not necessarily make you use up more gas, kasi while it is true that you step on the gas more to push a heavier load, so do you need not to step on the pedal longer to carry your car to a stop. u count on momentum to do that.
