What causes oil pressure to drop in a vehicle?
The oil level dropping below the minimum dipstick line is one of the most common causes of low oil pressure. This can happen at any time, even if you've recently had an oil change. Over time, engines burn oil more quickly. This is due to piston rings wearing, seals leaking, and so on.
How do you check an oil pump?
