Is your engine is suddenly making a lot of noise, it's probably time for an oil change. About how often should you change your oil?

Although the recommended interval for an oil change used to be every 3,000 miles, every 5,000-7,500 miles is more realistic due to modern lubricants. If you have a car that guzzles full-synthetic motor oil, you can expect to change your oil even less often.
