Gas is one of the few bills you pay several times a month, so small improvements add up fast. The good news: you don't need a new car or a magic gadget. Most of the savings come from how you drive, how you maintain your car and where you fill up. Here are 12 tips that work for almost any driver.
Driving habits that save fuel
1. Drive smoothly
Fast starts, hard braking and weaving through traffic burn fuel without getting you there much sooner. According to fueleconomy.gov, aggressive driving can lower gas mileage noticeably on the highway and even more in stop-and-go traffic. Accelerate gently, look ahead and coast toward red lights instead of racing up to them.
2. Slow down a little on the highway
Every car has a speed range where it is most efficient, and fuel economy usually drops off as you go faster above typical highway speeds, because wind resistance rises quickly. Dropping your cruising speed by 5 mph is one of the easiest savings there is, and it barely changes your arrival time on most trips. Using cruise control on flat highways helps you hold a steady speed.
3. Don't idle
An idling engine gets zero miles per gallon. If you are waiting in a parking lot, picking someone up or sitting in a long line that isn't moving, turn the engine off when it's safe to do so. Modern cars don't need a long warm-up in most weather; driving gently for the first few minutes warms the engine faster than idling.
4. Lighten the load and remove roof racks
Extra weight in the trunk makes the engine work harder, and roof racks or cargo boxes add drag even when they're empty. Clear out sports gear, tools and boxes you don't need, and take the rack off when you're not using it.
Car care that pays for itself
5. Keep your tires properly inflated
Under-inflated tires create more rolling resistance, wear out faster and are less safe. Check pressure once a month and before long trips, when the tires are cold. Use the number on the sticker inside the driver's door, not the maximum printed on the tire. A cheap AstroAI digital tire pressure gauge makes this a one-minute job, and a cordless tire inflator saves trips to the gas station air pump (which often costs money now).
6. Follow the maintenance schedule
A clean air filter on older cars, the right motor oil grade, and fixing a check-engine light all help your car run as designed. See fueleconomy.gov's maintenance tips for what matters most. Use the oil grade recommended in your owner's manual; it's there for a reason.
7. Use the fuel grade your car actually needs
If your owner's manual says regular, premium usually won't make the car faster or more efficient. That extra cost per gallon is money you don't need to spend. Only buy premium if the manual says it's required.
Paying less at the pump
8. Compare prices before you fill up
Prices can vary a lot between stations just a mile or two apart. Stations right at highway exits and in busy areas are often more expensive. A free gas price app or map lets you check before you go. Don't drive far out of your way, though: the detour can cost more than you save.
9. Stack cashback and loyalty programs
Grocery store fuel rewards, warehouse club stations and gas station loyalty programs can knock cents off every gallon. Fuel cashback apps can add more on top. ScanSave lists fuel cashback apps by state so you can see which ones work near you.
10. Pay with cash or debit where it's cheaper
Some stations post a lower price for cash or debit than for credit. If you pay off your card every month and it earns good rewards on gas, compare the two; otherwise the cash price may be the better deal.
Drive less without giving anything up
11. Combine errands into one trip
A cold engine is less efficient, so several short trips use more fuel than one longer loop covering the same stops. Plan errands in a route, do them in one outing and try to avoid rush hour when you can.
12. Share rides and use alternatives
Carpooling to work or school splits the cost. For short trips, walking, biking or public transit can save gas and parking. Working from home even one day a week cuts commuting costs noticeably.
Skip the gas-saving gimmicks
Be skeptical of devices or additives that promise big mileage gains. The U.S. government has tested many of these products, and fueleconomy.gov notes that most don't deliver meaningful savings. A fuel system cleaner such as Chevron Techron can be part of routine maintenance, but it's not a mileage miracle.
Be ready for the road
A breakdown or tow is one of the most expensive surprises a driver can face. A NOCO jump starter in the trunk can save a service call when your battery dies.
