Fuel prices may be out of your control, but your driving habits aren’t. How you drive can have just as much impact on your fuel economy as where you fill up. According to the U.S. Department of Energy, changing just a few common behaviors can help you boost gas mileage by 10%–40%—no apps or upgrades needed.
Here are the simplest, research-backed driving habits that can stretch your tank further.
- Avoid Rapid Acceleration and Hard Braking
Quick takeoffs and sudden stops waste fuel by forcing your engine to work harder than necessary. Smooth, steady acceleration and gradual braking conserve energy and reduce wear on your vehicle.
Tip: Use cruise control on highways when traffic allows. This keeps your speed consistent, which improves fuel economy.
- Obey the Speed Limit
Driving faster than 50 mph significantly reduces your miles per gallon. The Environmental Protection Agency (EPA) estimates that for every 5 mph you drive over 50, it’s like paying an extra $0.20 per gallon.
Try staying in the 55–65 mph range on highways. It’s safer and more efficient, especially for larger vehicles.
- Minimize Idling Time
Idling can use up to half a gallon of fuel per hour, depending on your engine. If you’re parked and waiting for more than 60 seconds, turn off the engine. This applies to curbside pickups, drive-thrus, and long red lights.
Modern engines are designed to handle frequent starts without issue, making this a simple way to reduce fuel waste.
- Remove Excess Weight
Every 100 pounds of extra weight can reduce your MPG by up to 2%, especially in smaller vehicles. Remove items from your trunk or roof that you don’t need, such as toolboxes, sports gear, or cargo racks.
If you drive a fleet vehicle, reducing payloads where possible can offer significant fuel savings over time.
- Maintain Proper Tire Pressure
Underinflated tires increase rolling resistance, forcing your engine to work harder. According to the National Highway Traffic Safety Administration (NHTSA), properly inflated tires can improve gas mileage by up to 3%.
Check tire pressure at least once a month—especially during seasonal temperature changes—and use the recommended PSI listed in your vehicle’s manual or door frame.
- Use the Right Oil and Replace Filters Regularly
Using the manufacturer’s recommended motor oil and changing air filters on schedule ensures your engine runs efficiently. Neglecting these can reduce mileage and strain your engine, increasing fuel consumption over time.
Check oil quality every 3,000–5,000 miles and replace air filters roughly every 12,000–15,000 miles, or more often if you drive in dusty conditions.
- Limit Use of Air Conditioning at Low Speeds
Running the A/C can lower fuel economy, especially in city driving. At lower speeds, opt for rolled-down windows when weather permits. At highway speeds, using A/C may be more aerodynamic than open windows.
Balancing comfort and efficiency takes trial and error, but adjusting your A/C use wisely can yield small but cumulative savings.
