Why does oil pressure light go on and off?

Another reason your oil light may come on is if the oil pressure is low. Low oil pressure means the pump isn’t circulating enough oil, or there isn’t enough oil in the system for the pump to circulate. The oil is important to keeping the surfaces lubricated, so if the oil light comes on and the pressure is low, pull over and turn off the engine.

What causes low oil pressure?

One of the possible low oil pressure causes is worn-out bearings. If you have driven the car for quite a long time, low oil pressure could occur due to worn out rod bearings and main bearings. The bearings also play an important role to keep up the right pressure of the oil.

Why does oil light come on at idle?

Sometimes when an engine is just slightly low, the oil light may come on at idle simply due to the lack of oil pressure when the motor is not working as hard.

How long after oil light comes on?

When you first start the engine, this light should come on for one or two seconds and then go out. If the light stays on, the vehicle is due for an oil and filter change. Vehicles equipped with an in-cabin messaging system will see an oil life of 10% to 100% displayed in the center of the dash that should go off in one to five seconds.
