What is the oil can icon on the car dashboard?
1 Answers
The oil can indicator light on the car dashboard is the engine oil warning light. There are generally two colors for the engine oil warning light: yellow and red. A yellow light indicates that the engine oil level is low, but the vehicle can still operate normally. A red light indicates a severe shortage or blockage of engine oil, requiring immediate stopping of the vehicle and calling for assistance. The following reasons may trigger the engine oil warning light: 1. Insufficient engine oil level: This reduces the oil pump's output or causes it to pump air instead of oil, leading to a drop in oil pressure. 2. Overheating engine: This can thin the oil, causing it to leak excessively through gaps and resulting in decreased oil pressure. 3. Damage or wear to oil pump components: Excessive gaps due to wear or improper assembly can prevent the oil pump from delivering oil or delivering it insufficiently. 4. Improper clearance between the crankshaft and bearings: Too tight increases oil pressure, while too loose decreases it. 5. Clogged oil filter or oil pickup screen: This can reduce oil pressure. 6. Faulty or malfunctioning pressure relief valve: If the main oil gallery's relief valve spring is fatigued, improperly adjusted, or if the valve seat and ball are worn or stuck by debris, the return oil flow increases significantly, lowering the main oil gallery's pressure. 7. Incorrect oil selection: Using the wrong type or grade of oil can lead to excessive leakage due to low viscosity, reducing oil pressure. 8. Leaks or blockages in the oil lines.
