When you wait too long to change the oil filter, it can become blocked with debris. Similarly, when your engine oil becomes too thick or is too thick, it can exceed the limits of the filter and how much it allows to pass through. With too much blockage, unfiltered oil can run in your engine for as long as you have the old filter in place. Again, this can lead to many engine issues that eventually lead to engine failure.
