How to Get Better Gas Mileage in a Subaru Legacy

Check the air pressure in your tires. Don't check your air pressure when the tires are hot. Heat makes them expand and you will get a false reading. If your air pressure is not at its full capacity it can cause your gas mileage to decrease by 3 percent. This adds up over time. If your air pressure is low, add air and keep all tires equal.

Have your Subaru Legacy's wheels aligned by a professional. If your vehicle isn't aligned properly it will not get as much horsepower which will decrease the gas mileage. Don't assume your wheels are properly aligned just because you bought it brand new.

Keep the brakes from dragging. They may need to be adjusted. This can be done at the same time as you get your wheels aligned. Making one appointment for both will cut down on the cost and will get your Subaru Legacy ready to get the best gas mileage it can get.

Get rid of extra weight. Weight causes your Subaru Legacy to work harder, which means it uses more gas. If your Subaru Legacy has a roof rack, remove it when you don't need it. The same goes for any work tools or equipment that you may be keeping in the car or trunk. Only add weight when you need to.

Turn off the air conditioning and roll down the windows. Air conditioning uses up gas, while having your windows down can cool you off with no addition loss of gas. Not using your air conditioner can use 5 percent less gas.

Make sure the gas attendant (or yourself, if you pump) puts the gas cap back on tightly. You can lose gas if the cap is not put back on correctly. Since you've paid for the gas, make sure you are not losing a drop of it.

Use the cruise control feature of the Subaru Legacy. Staying at a constant speed uses less gas than if you were constantly using the brake and accelerator. This is one reason why freeway gas mileage is higher than in-town gas mileage.
