A gallon of water is heavier (about 7 1/2 lbs per gallon) than gasoline (about 5.8 lbs per gallon).

This is also the reason that gas floats on top of water.

What is the difference in weight between gallon of water and gallon of gasoline?

Equivalent in what way? Gasoline and water are two entirely different chemical compounds. They have dissimilar physical and chemical properties because, well, they are different. Perhaps you are referring specifically to the weight of a gallon of each. If so, then the weight of a gallon of each substance is not equivalent because the gas is less dense than water, so a gallon of water weighs more. When referring to volume, a gallon of gas is equivalent to a gallon of water. Even a gallon of oxygen is equivalent to a gallon of water, in reference to volume. However, when dealing with gases, pressure, temperature, and the number of molecules of the gas must be taken into account.

The answer is really in relation to how much more work the car/vehicle has to do carrying more gas around. Then I suppose you have to offset it with how uneconomic it is to have to regularly stop and fill up. Slowing a car and then accelerating again wastes gas. I suggest removal of all stop signs in the US (I am from the UK by the way)!
