Many newer vehicles now come equipped with an sensor or monitor where a light on comes on indicating you should change the oil. If you are lucky enough to have one of these you will soon realize how much of a waste it would be to change your oil every 3,000 miles.
The common suggestion is to change the oil every 3000 miles. And numerous service stations and their mechanics gladly parrot this recommendation. After all, every time you come to change your oil, they will get paid. After every oil change, your windshield or the inside of your cars door is decorated with an oil change sticker, nicely telling you to come back in a few months or 3000 miles. Lovely.
