What does it mean when the oil can light comes on?

[StJayla]

The oil can light comes on due to the following reasons: 1. Insufficient engine oil level; 2. Overheating of the engine, which can thin the oil and cause significant loss through the clearance gaps, leading to a drop in oil pressure; 3. Damage to oil pump components or excessive clearance due to wear or assembly issues, resulting in the oil pump failing to deliver oil or delivering insufficient oil; 4. Clogged oil filter or oil suction screen, reducing oil pressure; 5. Improper clearance between the crankshaft and the bearings—too tight increases oil pressure, while too loose decreases it; 6. Oil leaks or blockages in the oil lines; 7. Malfunction or failure of the oil return valve; 8. Use of inappropriate engine oil.
