What is the Purpose of Motor Oil?

Motor oil keeps the engine running smoothly and helps give it a long life. Oil has several different purposes as it circulates through the engine.

  • Oil helps keep all the parts moving smoothly together.
  • Oil flows through the engine and carries particles and residue to the oil filter so that the engine doesn’t get clogged.
  • Protection against corrosion – Acid is a product of combustion engines. This acid damages the metal parts in the engine. The oil helps slow the corrosion process.
  • The movement of oil helps the coolant keep the engine from overheating.
  • The oil helps seal small gaps between parts in the engine.

What is a Fully Synthetic Engine Oil?

Synthetic engine oil is made of chemically engineered molecules that are all exactly the same size and shape under a microscope. Traditional engine oil is made of crude oil, which has molecules of all shapes and sizes.

The main advantage of a synthetic oil is its lifespan! It doesn’t break down as easily as crude oil. Not only can you go longer in between oil changes, but it will maintain stable oil levels in your engine in between oil changes.
