What is the first step in the order of oil flow in a motor?

The first step in the order of oil flow in a motor begins with the oil that resides in the oil pan. This component acts as a reservoir that holds the engine oil when the engine is not running. When the engine starts, the oil pump draws the oil from the oil pan to initiate the lubrication cycle. This initial step is crucial, as it sets the stage for the subsequent processes that ensure all moving parts of the engine receive adequate lubrication.

The oil in the oil pan is typically at the bottom of the engine and is the starting point for oil circulation. Without this reservoir, there would be no oil available for the pump to draw, which would prevent lubrication and could lead to engine damage. Understanding this first stage gives insight into the fundamental operation of an engine's lubrication system and the importance of oil management.
