Ways to Save on Gas at the Pump 

1. Shop Around

You can try to shop around in your local area for the cheapest gas that you can find but you shouldn’t go too far out of your way to try and get that best price unless you’re already traveling in that direction anyway.

2. Paying For Gas The Smart Way

One of the ways that you can save money at the gas pump is by using an automobile or gas rewards credit card. Automobile and gas rewards credit cards allow you to earn rewards with every dollar you spend! According to an analysis by
 
CardWeb.com   , a consumer could save as much as $300 a year on gasoline by choosing to pay with a gas rewards credit card at the pump. Gas rewards cards are available for just about every station — from Citgo to Shell — and offer between 1 percent and 10 percent back on gasoline purchases.

Some cards only offer the savings at specific stations, while others allow a user to fill-up anywhere. Additionally, all of the major reward cards in this space do not charge an annual fee.

  3. Buy Gas In The Morning Or Evening

Gasoline becomes denser in colder temperatures. Gas pumps are set to measure the volume of the fuel that you pump and not the density. This means that if you fill up your gas tank in the cooler morning temperatures, or in the colder evening hours, that you’ll be getting better fuel economy.

4. Buy Gas From A Busy Station

Try to buy your gas from a gas station that is consistently busy and therefore has its underground tanks filled on a regular basis. Gas stations that are slow will have gas that has been sitting in underground tanks for longer periods of time, leading to gas contamination. This contamination can mean that the gas you are purchasing is less powerful than fresh gas and will decrease your fuel economy.

4. High Octane Gas

Choose the right octane gas for your car. Unless your vehicle requires it, buying higher-octane gas is a waste of your money. The higher the octane, the higher the price.

5. Avoid Topping Off

Try to avoid over filling or “topping off” at the gas pumps. When filling your tank, the gas nozzle automatically clicks off when your gas tank is full. Too much gas will just slosh or seep out. In warmer weather, the gas will expand and may leak out.

6. Always Fill Up Your Tank

When you purchase just a bit of gas at the gas station the pump doesn’t have enough time to really activate, resulting in short bursts of fuel that may short change you from the amount of gas that you are purchasing.

The best time to replenish your gas tank is when you have half a tank or less left in your vehicle, or when you find a gas price that you just can’t afford to miss.

9. Avoid Buying Gas From A Just Replenished Gas Station

When a gas station has its underground tanks filled, the particles at the bottom of the tank are stirred up. These particles can become mixed in with the gas that you are putting into your car, which can lead to efficiency problems. The particles can clog your fuel filter, causing your car to stall and start with some difficulty.
 
10. Tighten The Gas Cap

It may seem like a small thing to do, but tightening the gas cap on your car will prevent gas from evaporating and escaping into the air. Loose, missing or damaged gas caps cause 147 million gallons of gas to evaporate each year, according to the Car Care Council. So be sure to tighten up that gas cap each time you fuel up your car. If you have a gas cap that doesn’t fit tightly, or you’ve lost your gas cap, buy a new one to replace it.
