Rental cars can be convenient for vacations, business trips, or when your own vehicle is unavailable. But one hidden cost that catches many drivers off guard is fuel. Between high pump prices and rental company fuel policies, it’s easy to overspend. With a few smart strategies, you can save money on gas while driving a rental car.
Decline Prepaid Fuel Options
Most rental companies offer prepaid fuel plans, letting you return the car empty. While this sounds convenient, it rarely saves money. You end up paying for a full tank whether you use it or not, often at prices above the local average. Instead, opt to refill the tank yourself before returning the vehicle.
Know the Closest Affordable Stations
Gas stations located directly near airports and rental return centers usually charge higher prices. Use apps like GasBuddy or AAA Gas Prices to find cheaper stations a few miles away. A quick search before dropping off the car can save several dollars per gallon.
Choose a Fuel-Efficient Rental
If possible, select a car with good gas mileage. Many rental companies such as Enterprise, Hertz, and Avis provide vehicle categories that highlight fuel-efficient options. Compact and hybrid cars typically offer the best value for long drives.
Use Loyalty and Rewards Programs
Some gas station rewards programs, like Shell Fuel Rewards and Exxon Mobil Rewards+, can still be applied when fueling a rental. Enroll for free to access cents-off discounts at the pump, even if you’re driving a car you don’t own.
Stack Savings with Cashback Apps
Fueling a rental car is also a great time to use cashback apps. With Fluz, you can instantly earn cashback with a BP gift card or get rewards with an ExxonMobil gift card when refueling. Apps like Rakuten and Ibotta also add savings on road trip essentials like snacks and groceries.
Keep the Tank Topped Off
Avoid last-minute refueling stress by filling up the night before returning the car. This way, you won’t be forced to settle for overpriced gas near the airport or face steep rental company refueling fees.
Conclusion
Saving on gas in a rental car comes down to preparation. Skip prepaid fuel plans, choose efficient vehicles, and use apps and loyalty programs to find the cheapest gas. With tools like Fluz and GasBuddy, you can ensure that your rental car trip is both convenient and budget-friendly.
