Oil Pressure
What is oil pressure?
Oil pressure is the force at which lubricating oil is circulated through the engine, and it is a vital indicator of engine health that the pilot must monitor in flight. It may be shown on a circular or linear gauge, as a numerical value, or grouped with other engine parameters on a digital display. Think of it as your engine's "pulse"—low or fluctuating oil pressure is an early warning of a serious problem.
