What happens when oil pressure drops too low?
If the pressure drops to the point where oil is no longer flowing freely around all the engine’s moving parts, unlubricated metal surfaces will come into contact. This results in friction, warping, seals breaking, and some other issues. In short, it’s a quick way to ruin an engine.
