Driving Habits That Save Fuel

Slow Down:
- Driving at 55 mph instead of 65 mph can save 6–8 mpg depending on your car.
- Speeding to 75 mph can cost you 6–7 mpg.

Drive Smoothly:
- Avoid hard acceleration and braking. This can save 2–3 mpg and extend the life of brakes and tires.

Maintain a Steady Speed:
- Use cruise control on highways to conserve fuel.

Reduce Drag for Better Mileage

Avoid Roof Cargo:
- Roof racks and carriers can reduce mpg significantly:
- Two bikes on the roof: -13 mpg in sedans, -7 mpg in SUVs.
- Empty roof rack: -5 mpg in sedans, -2 mpg in SUVs.
- Use hitch-mounted racks or keep the roof clear for road trips.

Air Conditioning vs. Open Windows

Air Conditioning (AC):
- AC use reduces fuel efficiency by 1–4 mpg on hot days.
- Use AC sparingly but prioritize safety and comfort, especially on long drives.

Open Windows:
- At speeds of 65 mph, open windows have minimal impact on fuel economy.

Common Myths and Truths

Warm-Ups Are Unnecessary:
- Modern engines don’t need warm-ups. Start driving gently right away.

“Cooler Gas” Doesn’t Save:
- Gas stored underground doesn’t change temperature much during the day.

Running on Empty Is Fine (Sort of):
- Cars have 1–2 gallons left after the low-fuel light comes on (~40–50 miles).
- Running low won’t harm the engine, but avoid it to prevent being stranded.

Premium Gas: Necessary or Not

Most Cars Run Fine on Regular Gas:
- Premium gas is only needed if recommended or required for high-performance engines.
- For everyday driving, regular gas often suffices.

Tire Tips for Fuel Efficiency

Maintain Proper Tire Pressure:
- Under-inflated tires can reduce mpg and compromise safety.
- Check tire pressure monthly for optimal performance.

Low-Rolling-Resistance Tires:
- Can improve mpg but may sacrifice wet braking or tread life.
- Prioritize safety first, then choose fuel-efficient options.

FAQs About Fuel Economy

• Does a dirty air filter hurt mpg?

• Not with modern cars. Dirty filters affect acceleration, not fuel efficiency.

• Are “no-name” gas stations lower quality?

• Independent stations use similar fuel to name brands. Look for Top Tier-certified gas for extra engine-cleaning additives.

Thing to Remember:
Drive smart, reduce drag, and maintain your vehicle to maximize fuel savings while staying safe on the road!
