Although it seems like a fairly simple process, filling up at a gas station takes a bit of getting used to. Here's a quick, easy tutorial on how to get gas at a gas station.
Know Your Car
You should know two things about your car before filling up at a gas station. First, you should know what type of gas it takes. Normal, slightly-better normal, premium, or diesel? The other thing you should know is which side of your car the gas tank is on. There is nothing more embarrassing than forgetting which side the gas tank is on.
Pay, Choose, and Pump
First, turn off your car and walk out to the self-service station. Insert a credit card (or a gas card, which will become your new favorite birthday present) into the credit card terminal. Don't forget to choose a grade of fuel. Take off the gas cap and insert the nozzle. Pull on the lever of the pump until it clicks.
Annoying Safety Regulations
Cue annoying safety video music! According to crazy regulations, you should turn your phone off whenever near a gas station. Also, you're not supposed to get back into your car because static electricity can start a fire.
Finishing the Job
Shake the nozzle in your tank to get every last drop in your tank. Be sure to take out the nozzle before driving away! Remember when I said that there was nothing more embarrassing than forgetting which side the gas tank is on? Well, I lied. There is nothing more embarrassing than driving away with the nozzle still in your car. So many bad things can happen from that. Newer gas stations typically have a different gas hose that prevent those "bad things" from happening. Also, be sure to put back on the gas cap.
And that's how to fill up at a gas station in a nutshell! I hope this helps!
