Motorists who still adhere to the old standard of changing their vehicles' oil every 3,000 miles are likely wasting their money. The majority of today's auto manufacturers now build vehicles that can go twice as long, if not longer, between oil changes. Many automakers now call for oil changes every 7,500 miles, and some go even further, recommending oil changes every 10,000 miles. Some vehicles can even go as long as 15,000 miles before needing an oil change. Vehicle owners should consult their owner's manuals for advice on how often their vehicles' oil should be changed. When establishing an oil change schedule for their vehicles, many drivers are hesitant to abandon the conventional 3,000 mile interval schedule that was long espoused by the auto industry. But advancements in technology have allowed manufacturers to recommend longer intervals between oil changes, which benefits motorists' bottom lines and even the environment. Rather than needlessly wasting perfectly good oil every 3,000 miles, in many instances motorists can now continue to use that oil twice as long, if not longer, reducing waste-oil dumping as a result. When consulting an owner's manual for recommended oil change intervals, owners should resist the temptation to follow the "severe" schedules listed in many owner's manuals. Such schedules are rarely applicable under normal circumstances, and only serve to waste drivers' money and oil.
