How to Fill Up a Gas Tank

on 1/15/2007 fdwalker.... Keeping your tank low may not cause damage to the fuel pump but you will suck up any crud in the bottom of your tank, causing filters to become blocked before their time or other blockages elsewhere in the system. Also less fuel in the tank means more air in the tank and this can cause evaporation of fuel.

Is this a fact?

on 11/25/2006 I still have trouble filling gas in that I can't lock the hose for it to pump automatically, so I end up holding the hose all the time the gas is pumping..any suggestions anyone?? Thanks :)

on 7/9/2006 When the gas nozzle clicks off, it means the gas tank is full. Don't try to round off your sale by adding more gas (topping off). When you do that, you are not getting the gas you're paying for. At the tip of the gas nozzle, there is a small sensor hole that senses when your tank is full. When gasoline covers that hole, the gas tank nozzle shuts off, and you are more than likely just increasing your price per gallon. The extra gasoline you are trying to click into your gas tank is being sucked back into the gas station's storage tanks or is in the hose.

Also, topping off will weaken the performance of your vehicle. Your gas tank needs extra room for the gas to expand (especially on hot days when gas warms up and expands). Topping off is a waste of your money, a contributor to air pollution, and will damage your car's system.
