No matter what vehicle you purchase, you’ll save some pain at the pump with proper maintenance. Increase your fuel efficiency with these great tips:

Give your engine a tune-up: If your engine is in need of a tune-up, chances are you are compromising your fuel economy. It could mean you have a more serious problem such as an electronic one. Replacing a faulty oxygen sensor for example can improve your MPG.

Maintain proper tire pressure: You can’t just set the correct tire pressure and forget it. The volume of air in your tires is constantly changing due to the passage of time and shifts in environment. Keep your tires inflated to the recommended tire pressure found in your owner’s manual to improve your gas mileage.

Use the recommended grade of oil that is energy conserving: Using a different grade than is recommended by the manufacturer can lower your gas mileage. To get the maximum fuel economy, the Department of Energy recommends using motor oil designated as “energy conserving,” as it contains friction-reducing additives.

Don’t carry extra gear: Extra weight can greatly reduce fuel economy. Take a look at what you are carrying around and remove anything you don’t need on a daily basis.
