What are the best ways to save on gas?

Here are a few ways you can pay less for gas beyond joining a membership program and paying with credit cards that offer fuel perks. Experts also share tips for cutting back on your gas usage.

  • Compare local prices: “There can be substantial variation in prices at the pump across neighboring counties,” says Francesco D’Acunto, an associate professor of finance at Georgetown University’s McDonough School of Business. Use websites and apps like GasBuddy and AAA to track local prices, and take note of prices in surrounding neighborhoods while you’re driving.
  • Fill up your tank on Sundays: GasBuddy found that Sunday is commonly the cheapest day to get gas nationwide, with Monday coming in second place. The worst days to get gas are usually Wednesdays, Thursdays and Fridays. Experts also don’t recommend getting gas directly before or after a holiday as prices tend to spike.
  • Download stations’ apps and cashback apps: Some gas stations have apps that let you make a free account and earn cashback or other perks over time, like Earnify, Exxon Mobil Rewards+, Shell Fuel Rewards, Inner Circle and Speedway Speedy Rewards. You can also download GasBuddy, an app that helps you find cheap gas and potentially earn rewards as you spend.
  • Pay cash: Some stations give you a discount if you pay with cash rather than with a credit card. “It’s pennies because they’re basically just not charging you the credit card fee, but it could save you a buck or two over time,” says Joe Adamski, a supply chain expert and senior advisory director at ProcureAbility. You’ll save more if you pay with a credit card that offers fuel perks, but if you don’t have one, using cash can help.
  • Fill your tank with regular gas, not premium: Most car engines are designed to run on regular gas (87 octane), so filling your tank with higher-grade gas won’t give you better mileage, says Adamski. That said, look at the manual your car comes with — if it specifically says to only use higher-grade gas, follow those directions.
  • Don’t put additives in your tank: There are some on the market that brands say can give you better mileage, but there’s not enough solid research about them to draw conclusive findings yet, and you don’t want to use something that could potentially damage your car, says Adamski.
  • Check your tire pressure: You lose about 0.2 percent of gas mileage per every 1 psi drop in the average pressure of all tires, according to the U.S. Department of Energy.
  • Watch your speed: “Rapid decelerations and accelerations drive additional gas usage,” says Adamski. “Also, getting over 60 miles-per-hour starts to drastically increase fuel consumption on a mile-per-gallon basis.”
  • Clean out your car: Driving with extra weight from trailers, roof racks or anything else you mount to your vehicle lessens your gas mileage, according to the U.S. Department of Energy. Remove anything you’re not using to lighten the load.
  • Cut down on driving: Not to state the obvious, but being intentional about how often you drive can stretch what’s in your tank.

Frequently asked questions

Gas is so expensive right now due to significant global supply chain distributions caused by the war in Iran and resulting blockages in the Strait of Hormuz, a waterway between the Persian Gulf and the Gulf of Oman that’s critical to oil transportation, says D’Acunto. Tankers filled with oil are trapped in the strait, and because they can’t get through, global supply is restricted. That’s causing the cost of a barrel of oil to skyrocket, which directly relates to prices at the pump. “The price of gas is based on the overall global availability of oil, so even if there’s a shock as far away as in Iran, gas prices in the U.S. are affected,” says D’Acunto.

Gas prices won’t go down any time soon, experts told me. Economic and supply chain experts I talked to estimate that it will take about two to three months for costs to drop once the war with Iran is over and the Strait of Hormuz reopens— there’s currently no estimate for when that will be, so expect prices to stay high through at least the summer. That’s the case even though the cost of oil fluctuates daily in response to current events. “Just because the price of a barrel of oil goes down on a given day doesn’t mean it translates into the retail price going down,” says Adamski. “The price of gas tends to increase quickly with bad news, and it comes down slowly as things stabilize, an economic concept commonly called ‘rockets and feathers.’”

The federal gas tax is 18.4 cents per gallon of gas and 24.4 cents per gallon of diesel, according to the U.S. Energy Information Administration. On top of the federal gas tax, you also pay additional state taxes.

No, the federal gas tax is not currently suspended in the U.S. at the time of publication. President Donald Trump proposed suspending it, which would require congressional approval, but it’s never been done before. While suspending the federal gas tax would bring fuel prices down, they’d still be elevated compared to prices before the Iran war.

Yes, there are different gas prices in different states, says D’Acunto. How gas is taxed differs from state to state, which is one of the biggest reasons why gas typically costs more per gallon in California compared to Oklahoma, for example. But other factors play a role, like state-specific environmental regulations and transportation costs.

Groceries and air travel are the two main things likely to get more expensive in the coming weeks due to gas prices.

  • Groceries: Farms and manufacturing plants run on a lot of diesel and other petroleum products, including fertilizer, much of which is transported through the currently blocked Strait of Hormuz. Since farmers and manufacturers will have to pay more for necessary supplies and transport products, shoppers will, too, says D’Acunto.
  • Air travel: All transportation industries are impacted by increased gas prices, but air travel takes the biggest hit, says D’Acunto. “Jet fuel is based on very short-term price determinations, so every single shock that happens today will immediately spike up costs for travelers,” he says. “It will be reflected in the price of tickets, and it may even result in flight cancellations if it becomes unprofitable for airlines to run.” Adamski also expects airlines to raise prices on baggage, in-flight amenities and other add-ons as they try to make up for what they’re losing.
