Why does my oil pump have low pressure?

• thicker oil creates cavitation–the formation of air bubbles in the low pressure area of the pump. Cavitation damages the surfaces in the pump and introduces air bubbles to the oil. Air bubbles prevent adequate oil flow to bearings and act as an insulator, further prevent proper oil cooling.

What does the oil pressure low stop engine message mean?

This helps ensure that the pressure within the system does not overshoot its higher limit. The problem is that this valve can also get damaged.

Why is the oil pressure warning light still on?

If you have refilled your engine oil with a new one but the light is still on, the culprit could be the engine pressure sensor. The sensor is connected through a circuit from the engine to the dashboard. With time the sensors get filled with dirt and this reduces their ability to detect low oil pressure effectively.
