If you already know about this tip, you are probably someone who reads manuals and instruction books. Have you ever pulled into a gas station and not been able to remember which side of your vehicle your gas tank is one? Or, are you driving an unfamiliar car and just have no idea which side it is on? After years of poking my head out of the window, adjusting the side view mirrors to try and see it, guess what? The answer was staring me in the face. Take a look at your gas gauge and you will see an arrow either to the right or to the left of it…. Problem solved. That is the side that your gas tank is on.
