Your car may have a maintenance warranty, therefore allow the dealer to handle the work. Familiarize yourself with what is covered and what isn't, handling uncovered work yourself to save money.
Change your oil – Oil changes and oil filter replacement intervals are typically much longer than the once recommended 3,000 miles or 3 months. Nevertheless, follow car manufacturer guidelines to ensure that your car is maintained accordingly. Old oil affects gas mileage and does not offer optimum protection for your engine.
Check your tires – For every 1 point drop in tire pressure, gas mileage is reduced by .3 percent. That may not sound like much, but tires underinflated by 10 PSI will cost you to expend 3 percent more in gas. Besides, underinflated tires are dangerous as they are prone to blow outs and excessive wear.
Maintain your speed – A steady speed, particularly on the highway, will help you to squeeze more miles out of every gallon of gasoline. On long trips, use your cruise control to gain improved fuel economy. Use the lowest gear possible on the open road.
Ease up on the pedal – Lead foot driving will sap your fuel economy. When the light turns green, gradually press down on the accelerator to get your car up to the posted speed. On the highway, pass with care, and reduce your speed and get out of the left lane.
Tune it up – Tune ups intervals have also changed with spark plugs now lasting 30,000 to 100,000 miles. However, once the spark plugs begin to misfire, gas mileage will plummet. Replace spark plugs and plug wires as needed. Change the air filter at least once annually. Replace the fuel filter the moment your OBD-II system (idiot lights) signals that this is due.
Reduce your weight – No, not your bodily weight – although that might be a good idea for some people! Rather, remove excess stuff from your car, particularly in the trunk. For every 100 pounds of excess weight, your gas mileage will drop by 1 to 2 percent.
Follow manufacturer instructions – Familiarize yourself with your owner's manual and follow the maintenance instructions accordingly. The moment a problem arises, address it to avoid breakdowns and to extend the life of your vehicle. Don't ignore the dashboard light – a failed oxygen sensor can cause your gas mileage to drop by more than one-third.
