"When prices are dropping like this, it's tempting to wait until your gas tank is almost empty to fill up again, but doing that regularly can actually damage your vehicle and cost you more money over the long run,'' said Jeffrey Spring, the Automobile Club of Southern California's corporate communications manager.
"We recommend that drivers keep at least a quarter-tank of fuel in their vehicle at all times to avoid overheating the electric fuel pump or causing tank sediment damage to the fuel pump pickup, the fuel filter or the fuel injectors."
