- Low oil pressure
- Low oil level
- Oil pump failure
- Faulty oil pressure sensor
Here are some possible reasons for the oil light coming on after a recent oil change:
- Incorrect Oil Viscosity: If the wrong type of oil was used during the oil change, it may have the incorrect viscosity for the vehicle's engine. This can cause low oil pressure and trigger the oil light.
- Insufficient Oil: If not enough oil was added during the oil change, the oil level may be too low, resulting in low oil pressure and the oil light coming on.
- Oil Filter Issue: If the oil filter was not properly tightened during the oil change or is defective, it can cause an oil leak, leading to low oil pressure and the oil light turning on.
- Faulty Oil Pressure Sensor: The oil pressure sensor, which monitors oil pressure and triggers the oil light when it's too low, could be faulty and sending a false reading, even if the oil pressure is normal.
It is recommended to check the oil level and condition using the dipstick to verify that the oil level is correct and the oil appears clean. If the oil looks dirty, it may need to be changed again.
If the oil level and appearance seem normal, you should have the oil pressure tested to determine if there's a problem with the oil pressure or the sensor. This can be done by a mechanic or an automotive service center.
