Why regular oil changes are important?

Your engine has a lot of moving and
rotating parts and needs to be well lubricated. That's the function of
the engine oil. As you drive, engine oil gradually degrades. It loses
its lubricating qualities and carbonizes under high temperatures. If you
change you oil regularly, you keep your enigne clean and well
lubricated inside, see the photo. If you continue driving much longer
past the regular oil interval, the friction slowly increases causing
mechanical wear and the engine slowly gets contaminated with carbon
deposits or sludge (in the photo).
