Beyond just lubricating the moving metal parts, engine oil cleans the interior by carrying away dirt and debris, cools the engine by reducing friction, and seals the gaps between pistons and cylinders. In severe cases, the lack of lubrication causes metal-on-metal contact, leading to scored cylinder walls, damaged bearings, and the eventual need for a costly engine rebuild or replacement.

You should consult your owner’s manual, where you will find specific guidelines based on your engine design, often ranging from 5,000 to 10,000 miles for synthetic blends or full synthetics.
