What is the function of the bar oil in a chainsaw?

Explanation:
Bar oil’s job is to lubricate the bar and chain to reduce wear and heat. As the chain teeth slide along the bar, friction can cause rapid wear and overheating. The oil is pumped to the bar/chain interface, forming a protective film that lets the chain move smoothly, which helps extend chain life and maintain cutting performance. It is not used to fuel the engine, clean the air filter, or cool the spark plug.
