With fluctuating gas prices, finding ways to save money at the pump is more important than ever. Here are five quick and effective strategies to help you reduce your fuel costs:

1. Drive efficiently

Aggressive driving—like speeding, rapid acceleration, and hard braking—can decrease your fuel efficiency big time. By driving more smoothly and sticking to speed limits, you can actually improve your gas mileage. (As an added bonus, you’ll also avoid getting speeding tickets!) Use cruise control on highways to keep your speed constant and burn less gas. If you’re going to be idling for a long time, shutting off your car can also help save gas.

2. Keep your car well maintained

Regular car maintenance can mean better fuel efficiency. Keep your tires inflated to the manufacturer’s recommended pressure; underinflated tires can hurt your gas mileage. Replace your air filters, change your oil regularly, and make sure your engine is running smoothly. A well-maintained car uses gas more efficiently and makes every tank go farther.

3. Use gas rewards programs

Lots of gas stations have loyalty programs that will give you discounts or cashback on your gas purchases. Sign up for these programs to earn points or savings every time you fill up. Apps like GasBuddy can also help you find the cheapest gas prices in your area, to help you save even more. Combining rewards programs with finding the lowest prices can maximize your savings.

4. Streamline: travel lighter, and more aerodynamically

Carrying excess weight in your car can decrease fuel efficiency. Remove unnecessary items from your trunk and backseat (no, we don’t mean getting rid of your kids!) to lighten the load. It can also be helpful to improve your car’s aerodynamics by removing roof racks or carriers when you don’t need them. All of this will help your car use less fuel, especially on long trips.

5. Plan and combine trips

Carefully planning your errands and routes for max efficiency can save you time and gas. Try to do multiple errands in one trip instead of making multiple short trips. Use navigation apps to find the most efficient routes and also avoid heavy traffic. Carpooling with friends or colleagues is another good way to share the cost of gas and reduce your individual expenses.
