Oil pressure is a crucial component for the smooth, efficient operation of any engine. Net oil pressure is a complex measurement that requires taking into account all of the fuels, lubricants, and other fluids that come together to create the ideal effect. The official business definition of net oil pressure can be defined as the overall difference between the amount of oil supplied to the engine by the pump and the amount of oil drained. This quantity needs to be kept within specific parameters in order to keep an engine running safely and efficiently. By closely monitoring net oil pressure, engine parts are better protected, resulting in improved longevity and performance.
