Tips to improve your gas mileage and fuel efficiency.

How do I Improve my Gas Mileage?

With the rise in gas prices, it is a great time to reflect on your driving habits. There are a few simple things you can do to improve your car's fuel efficiency. 

Limit your idling. Idling uses more fuel than restarting your car and gives off 80% more pollution than when your car is in motion. When you are waiting for someone, consider turning your car off. 

Keep your speed steady. After you hit 45-50mph, your car begins to be less fuel efficient, and it gets worse as you go faster. It's a good idea to use cruise control when possible. Additionally, rapid acceleration and hard braking use up fuel quickly, so you will also want to avoid those actions when you can. 

Check your tire pressure. When your tires are under inflated, fuel consumption can increase by as much as 3%. You will also risk wearing down your treads faster. 

Perform regular maintenance. When you follow the maintenance schedule recommendations provided by your car's manufacturer, your vehicle will be more fuel efficient. Dirty air filters, spark plugs, and connections can all affect your fuel economy. Make sure to schedule regular tune-ups with Paul Campanella's Auto and Tire Center to keep your car running efficiently.
