You should get your oil changed about every 4 months or 5,000 miles, depending on the manufacturer. Regular changes to your oil is a great way to extend the overall life of your vehicle. Even if you do not drive as much, moisture can make the engine oil contaminated. Eventually, those contaminates will turn into sludge, which can lead to engine failure. As many of the quick oil service shops, we do not use recycled oil. We only use specified grades from manufactures to enhance the life of your engine.
