All metal parts need to keep in touch to operate flawlessly. And it will be possible by having a solid dose of the lubricant because it delivers a thin film of oil and acts as a blockade among the parts.
  • The second purpose of using motor oil is to cool the engine’s pieces far away from the water jacket. In a few vehicles like motorbikes, the conduction is oil-cooled.
  •  The purpose is to catch some potential matter that slips throughout the piston ring. The piston ring can’t make air-tight seals that guide burning items like carbon elements to slip throughout the ring and the piston chamber.
