Oil and Oil Filter Replacement
Having your oil and oil filter changed, at least as often as recommended by the manufacturer, is likely to generate the single biggest return on your investment in routine auto service and maintenance. Replacing the dirty oil and filter will help protect the internal parts of the engine from premature wear. It's important to use the recommended grade of oil for your vehicle for the best protection and fuel mileage. See your vehicle owner's manual for the recommended oil change interval, or follow the oil-life monitoring system, if equipped.
