How to Improve Your Gas Mileage
You can boost your fuel economy by 7% to 40% with simple changes to how you drive and maintain your vehicle. Most improvements come from driving habits, tire care, and regular maintenance.
Change Your Driving Habits
Drive at steady speeds. The biggest fuel savings come from smooth, consistent driving. Driving 5 to 10 mph slower than normal saves 7% to 14% on gas. Gas mileage drops rapidly once you hit 50 mph, and each extra 5 mph is like paying $0.31 more per gallon.
Go easy on the accelerator and brakes. Hard acceleration and sudden braking drain gas quickly. Rapid acceleration and braking lower fuel economy by 10% to 40% in city driving and 15% to 30% on highways. Instead, accelerate gradually and coast toward red lights to keep momentum.
Use cruise control. When driving on highways, cruise control maintains a consistent speed and can save up to 14% on gas.
Avoid idling. Engines burn up to half a gallon of fuel per hour while idling. If you're stopped for more than a minute, shut off your engine. It only takes about 10 seconds worth of fuel to restart a warm engine.
Maintain Your Tires
Check tire pressure monthly. Underinflated tires create more rolling resistance, forcing your engine to work harder. Proper tire pressure reduces friction with the road and improves gas mileage by up to 0.6% on average. Use a free pressure gauge at most gas stations and inflate to the recommended PSI in your vehicle's manual or door jamb.
Get tire alignment checked. Misaligned tires wear unevenly and reduce fuel efficiency. Improper alignment is like pulling a tire sideways for 102 miles every 20,000 miles. Get tires realigned and rotated every 6,000 miles or every other oil change.
Plan Smart Routes
Combine trips into one journey. Multiple short trips waste gas because your engine needs to warm up each time. Consolidating errands into one trip avoids unnecessary warm-ups and reduces total driving time.
Avoid rush hour traffic. Stop-and-go traffic forces constant acceleration and braking. Driving during off-peak hours reduces idling time and fuel consumption.
Remove extra weight. Heavy loads force your engine to work harder. Clean out your trunk and remove items you don't regularly need. Every pound counts.
Keep Up With Maintenance
Regular service keeps your engine running efficiently. A well-maintained car doesn't have to work as hard, which means better gas mileage. Schedule services with a qualified technician and follow your vehicle's maintenance schedule.
Tracking these changes helps you see real savings at the pump. Small adjustments compound over time into significant fuel cost reductions.
