What Causes the Oil Light to Come On When Starting the Car?
The oil light on your dashboard is triggered by the engine’s oil pressure sensor, which monitors the oil pressure in your engine. When the sensor detects low oil pressure, it sends a signal to the dashboard to illuminate the oil light. There are several reasons why the oil light might come on when starting the car:
-
Low Oil Level
-
Dirty or Clogged Oil Filter
-
Worn or Damaged Piston Rings
-
Incorrect Oil Viscosity
-
Faulty Oil Pressure Sensor
Why Does the Oil Light Go Off After a Few Seconds?

-
The oil level in the engine is sufficient, and the pressure sensor detects the oil pressure increasing as the engine warms up.
-
The oil filter is clogged, but the engine is able to pump oil through it, causing the pressure sensor to detect the correct oil pressure.
-
The piston rings are worn or damaged, but the engine is able to compensate for the loss of compression, causing the oil pressure sensor to detect the correct oil pressure.
-
The oil viscosity is incorrect, but the engine is able to adjust to the new viscosity, causing the oil pressure sensor to detect the correct oil pressure.
-
The oil pressure sensor is faulty, but the engine is able to function normally, causing the oil light to go off.
What to Do If the Oil Light Comes On When Starting the Car?
