When the level gets lower than it should, an electrical switch inside the float will trigger the low oil level indicator to come on. The low oil level warning light is similar to the low oil pressure warning light.
What happens when 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.
Why is my car oil pressure low?
The low oil pressure light is a warning that there’s not enough oil pressure or that the oil level is too low. This prevents the oil from going through the narrow passages to provide sufficient lubrication. Not enough or worn-out oil – Maintenance on any vehicle is key to keeping it on the road.
