Maybe you can answer this:
some people try to squeeze every drop of gas they can into their tank just so they can round up to the next dollar. Have heard this isn't smart, because if the tank's too full, the gas on top will just evaporate. Is this true?? Thanks again.
I don't know about evaporation, but I used to be one of those who tried to fill the tank tothe top. That was a bad move. I had a Caravan with a canister in the fuel system that was filled with charcoal. What the mechanic told me was that the extra fuel didn't allow for expansion in the tank, so when the expansion took place it increased the pressure in the canister. The result was I ended up with charcoal all through the throttle body. I had a friend tell me he had a similar experience with his car. I asked, and yes he also tried to fill 'er up to the top.
Needless to say I don't fill my vehicles to the top anymore.
Life is not a problem to be solved, it is an adventure to be lived.
I always top off. I mean with diesels I keep on pumping till I see fuel level staying 1" below the neck. With gasoline I squeeze the trigger 2 or 3 more times after the first kick, what still will not show fuel in the neck, but usually gives us additional gallon in the tank.
Not a problem if you own vehicle design to carry the fuel.

Well, I am a mechanic the reason you do not over fill is the reason previously mentioned. most newer vehicles have valves in the lines to prevent the gas from entering the evap system however some does get through if you overfill your tank. The evap works in away where it takes vapour from the engine and it adheres to the filter in canister. Now when you get raw fuel in there it damages the canister. Some people will complain of a fuel smell when they sart the vehicle and this is normally why. So do not over fill go to first click and stop
