I had to take a car in for service this morning as a favor, and as I typically do I killed the time waiting by reading the professional memos posted at the cubicle I was seated at. This time, it was suggestions for maximizing the gas you get at the pump.
* Fill up early in the morning, when the temperature of the underground gas tanks is lowest, which minimizes fuel volume.
* Pump at the low or medium speed (most nozzles have three speeds), which minimizes vapor.
* Fill up when your tank is half full/half empty. This also minimizes the space in the tank taken up by vapor.
* If you see a gas truck at a filling station, don't stop at it. If they're filling the tanks, it kicks up sediment.
Side note: the dirt-cheap new Tata may or may not mean $5 gas in Illinois.
