What happens if engine oil pressure is low?
When engine oil pressure drops, friction between different parts increases. This results in a steep decline in engine performance. Watch out for common signs of decreased engine performance such as a reduction in fuel economy, loss of power, and engine stalling.
What are three common low oil pressure problems?
5 Causes of Low Oil Pressure
- Oil Level Is Too Low. The oil level dropping below the minimum dipstick line is one of the most common causes of low oil pressure.
- The Viscosity of the Oil Is Too High or Too Low.
- Signs of Engine Wear.
- Oil Pump Failure.
- Clogged or Dirty Oil Filter.

One way to fix oil pressure in this case is to use a higher-viscosity oil, such as switching from 5W-20 to 10W-30.
