# 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.
