Changing the lubrication oil for the engine is the most basic maintenance you must do at the recommended intervals to keep the engine from having unwanted problems while lasting for hundreds of thousands of miles.


Neglecting changing the oil with the correct grade of oil can lead to oil consumption, increased internal wear on vital engine parts, increased accumulation of sludge in the engine, carbon build up on the valves, and malfunction of computer controlled systems that lead to engine warning lights coming on.
