What are the reasons for the engine oil light to illuminate?

[BrynleeRose]

The reasons for the engine oil light to illuminate include: 1. Insufficient engine oil level, which reduces the oil pump's output or prevents it from pumping oil due to air intake, leading to a drop in oil pressure; 2. Overheating of the engine, which can thin the oil, causing it to leak excessively through the gaps and resulting in decreased oil pressure; 3. Damage to the oil pump components or excessive gaps due to wear and tear or improper assembly, leading to insufficient or no oil output; 4. Improper clearance between the crankshaft and the bearings—too tight can increase oil pressure, while too loose can decrease it; 5. Clogged oil filter or oil suction screen, which can reduce oil pressure. If the engine oil warning light comes on while driving, find a safe place to stop and check. If the vehicle is running normally, you can continue driving to the nearest 4S shop for inspection, but remember to slow down and drive carefully.
