Why is the oil can indicator light on the dashboard constantly illuminated?

[RobertLynn]

The reasons for the oil can indicator light on the dashboard staying on are: 1. The engine oil viscosity is too high; 2. The pressure relief valve is clogged or improperly adjusted; 3. Insufficient engine oil level; 4. Excessive engine temperature; 5. Damage to oil pump components; 6. Clogged oil filter or oil suction screen; 7. Malfunction or failure of the oil return valve. The solutions for the oil can indicator light staying on are: 1. Replace the engine oil; 2. Adjust the pressure relief valve; 3. Top up the engine oil; 4. Cool down the engine; 5. Replace the oil pump; 6. Clean the oil filter and oil suction screen; 7. Replace the oil return valve. Dashboard indicator lights and their functions include: 1. Door status indicator: Shows whether the doors are fully closed; 2. Battery indicator: Displays the working status of the battery; 3. Brake pad indicator: Shows the wear condition of the brake pads.
