Fuel Saving Tips
Make sure to keep your car maintained. A good fuel filter, clean air filter and oil changes on regular intervals can help your gas mileage. Air filters need to be changed every 15 to 20k miles (if you run synthetic oil then roughly every other oil change you should change the air filter too).
