Fuel Saving Tips
Modern cars - for the last 25 years or so have had a charcoal filled evaporation canister attached to the refueling system to capture fuel vapors and prevent them from escaping to the atmosphere. Yes - you can slowly keep pouring gas in after the pump has automatically clicked off as several people on here have said to do...but guess where that gas goes? It's not in the tank. It's overflowing into the evap cannister and will eventually damage your emissions system. Simply put - don't do this. Stop when the pump shuts off.
