I don't know if it's true but I was told a few years ago that when using the fuel nozzle you shouldn't press the trigger all the way back but should allow the fuel to flow at a decreased rate. The reason I was given for this is due to the petrol pump reading the flow of fuel at the nozzle but when the fuel pump is delivering at a high rate air gets mixed in with the fuel. This results in the pump meter reading both the fuel and the air and thus you pay for air as well as fuel. If you only pull the trigger halfway back there is not so much air mixed with the fuel.I don't know if the above is true or just an urban myth however, I don't pull the trigger right back and the fuel doesn't froth as much as when the trigger is pulled right back.There's also the reasoning to keep the tank full to prevent evaporation. This sounds a reasonable assumption however, the fuel tank in a car takes about 5-6 gallons, that's an awful lot of weight to be carrying around using fuel to carry it (even if it is being burnt off).Maybe someone can confirm or dispel the theories?
