In a nutshell, there are 3 roles that the oil plays in an engine.
- It cleans the engine
- It maintains temperatures and
- It lubricates the engine for a safer operation.
Let’s keep this in mind as in the following paragraphs you would learn that why we need to change the motor oil so often.
We need to get the engine oil changed when it loses its property to perform all or any of the above-mentioned function efficiently. Over the time the oil would accumulate dirt, be saturated or even get oxidized. The oil would lose its properties after repeated functions and then it would be wise to replace it immediately.
