tighten your gas cap to reduce pollution
Make sure you tighten your gas cap fully after refueling. You can tell it is tight because modern caps reach a certain torque and then start to spin more freely while making a distinctive sound.
Significant amounts of gasoline vapor can escape from the tank (30 gallons per year) which contributes to pollution. In addition, the closed-loop fuel system forces vapor into a recovery tank to reduce smog. This system doesn't work properly if your gas cap is not tight.
When replacing a lost gas cap, get the right one from your dealer. A 3d party "fits-good-enough" cap is not good enough.
