09 mileage - Toyota Yaris Forums

To each his (or her) own, but I have no desire to run my car (a Cobalt, but brand doesn't matter for this discussion) down to the very last drop in the fuel tank.

As someone mentioned earlier, the fuel pump is cooled by the gas in the tank, and running the tank level too low can be harmful to it.

They say that in cold weather it is good to keep the tank above the 1/4 tank level to reduce condensation of moisture in the tank. Where there is no fuel, there is air, and air has moisture in it. When the air cools, it will not hold the moisture, and condensation occurs, which puts water in your gas.

Also, why take the chance of running out of gas?

Maybe I'm just missing something? Why would a person want to run the tank down to the last drop before filling up?
