What does it mean when the engine oil light flickers on and off?
1 Answers
The engine oil light flickering on and off is a normal phenomenon during vehicle self-check. When the vehicle is powered on, the self-diagnosis system activates, causing the engine oil light to illuminate. After the vehicle runs for a while, if the system detects normal oil pressure, the light will automatically turn off. However, if the oil light flashes while driving, it indicates an oil system abnormality, requiring immediate parking for inspection or a visit to a 4S shop for maintenance. Possible causes for the oil light flashing include: 1. Insufficient oil level reduces the oil pump's output or causes air intake, leading to pressure drop; 2. Engine overheating accelerates oil aging, deterioration, and thinning, potentially causing leakage through gaps and pressure reduction; 3. A clogged oil filter can cause oil pump pressure fluctuations.
