With popular smartphone apps from GasBuddy and AAA, drivers can find the cheapest gas station in their area.

Check your credit card rewards
Some credit cards offer bonus rewards when paying for gas. Websites including WalletHub Opens a New Window. allow users to sort through credit cards that offer fuel rewards. For example, the Bank of America Cash Rewards credit card offers 3% cash back on gas, compared to 2% at grocery stores and 1% on other purchases, according to WalletHub. Grocery chains like Safeway and Kroger also offer fuel discounts in partnership with gas stations.

Avoid gas stations on weekends
During a period of rising gas prices, drivers should plan on filling up the tank in the morning. Gas stations typically set prices early, around 10 a.m. Commuters should also avoid buying gas on Friday, Saturday or Sunday, when gas stations anticipate strong demand. Experts say it’s best to visit the gas station on Wednesday.

Pay cash, not credit
Most gas stations charge extra for customers who choose to pay with plastic. Paying in cash can often save as much as 10 cents per gallon.

Easy on the gas pedal
Quick acceleration, braking and speeding can cut gas mileage by 10% to 40% in stop-and-go traffic, according to FuelEconomy.gov . To save gas, drivers can gradually accelerate, allow their vehicles to coast and avoid slamming on the brakes when approaching a red light. Using cruise control also helps save gas.

Pack lightly
Excessive weight can hurt fuel economy, so pack lightly when traveling. FuelEconomy.gov also advises against using cargo carriers and packing items on roof racks.

Activate engine stop-start technology
Many modern vehicles have engine stop-start technology, which automatically shuts down the engine when idling at a red light and restarts it when the brake is released. Some cars don’t allow drivers to turn the system off, but make sure stop-start is activated to help save gas. Idling an engine can use more gas than restarting it.

Give your car a tune-up
Cars that are properly maintained and pass emissions tests can improve gas mileage by an average of 4%, according to FuelEconomy.gov. Tires that are inflated to the manufacturer’s specifications offer a 0.6% benefit to fuel economy on average. Tire pressure specifications are typically found in the driver’s side door jamb, the glove box or the owner’s manual.
