⚠️ If you never perform an oil change on your vehicle, you could be looking at engine damage, reduced performance and costly repairs.
Watch what happens to motor oil over time and why you periodically need to change oil.
Is flushing an engine a good or bad idea?
An engine that is properly maintained should have no sludge. However, that being said, there are reasons you might encounter an engine that is sludgy.
