What to Do When the Oil Can Light Comes On?
1 Answers
The oil can light on the dashboard is the engine oil pressure warning light. If the oil can light comes on, it indicates an issue with the engine oil that needs to be addressed. Below is a detailed analysis of the specific reasons why the oil can light may illuminate: 1. Insufficient engine oil level: This reduces the oil pump's output or prevents it from pumping oil due to air intake, leading to a drop in oil pressure. 2. Damaged or malfunctioning oil return valve: If the main oil passage return valve spring is fatigued, softened, or improperly adjusted, or if the valve seat and steel ball's mating surface is worn or stuck by debris, causing incomplete closure, the return oil volume will significantly increase, and the main oil passage's pressure will drop accordingly. 3. Incorrect engine oil selection: Using the wrong type or grade of oil can cause excessive leakage due to low viscosity during engine operation, resulting in reduced oil pressure. 4. Engine overheating: Excessive scale in the engine cooling system, poor heat dissipation, prolonged overload operation, or delayed fuel injection timing can all cause the engine to overheat. This accelerates the aging, deterioration, and thinning of the engine oil, leading to leakage through various clearances, pressure drop, and illumination of the oil warning light.
