What does a kettle and a drop of water mean in a car?

[JesseLynn]

A kettle with a drop of water is the symbol for the engine oil warning light. Here are the relevant details: Hazards: Only normal oil pressure can ensure that oil is delivered to all friction surfaces of the engine. Pressure that is too high or too low will affect the normal operation of the engine and may even cause damage to engine components. Therefore, when the oil light comes on, the engine should be stopped immediately to identify the cause, and work should only continue after the issue has been resolved. Reasons for the warning: Insufficient oil quantity, which reduces the oil pump's output or prevents it from pumping oil due to air intake, leading to a drop in oil pressure. Overheating of the engine can thin the oil, causing it to leak excessively through the gaps and resulting in decreased oil pressure. Damage to oil pump components or excessive gaps due to wear, assembly issues, etc., can cause the oil pump to fail to deliver oil or deliver insufficient oil. Improper clearance between the crankshaft and the bearings—too tight will increase oil pressure, too loose will decrease it. Clogged oil filters or oil pickup screens can also reduce oil pressure, among other issues.
