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

The oil can light on the dashboard is the engine oil warning light. A yellow light indicates that the engine oil is starting to run low but the vehicle can still operate normally, while a red light means the engine oil is severely low, and you should stop immediately and call for a tow truck. Below are the specific reasons why the oil can light may come on: 1. Insufficient engine oil level, which reduces the oil pump's output or prevents it from pumping oil due to air intake, leading to a drop in oil pressure. 2. Overheating of the engine, which thins the engine oil, causing it to leak excessively through gaps and resulting in decreased oil pressure. 3. Clogged oil filter or oil suction screen, which can also reduce oil pressure. 4. Incorrect engine oil selection. Using the wrong type or grade of oil can increase leakage due to low viscosity during engine operation, thereby lowering oil pressure.
When that oil can icon lights up on the dashboard, my heart instantly sinks - it's definitely an oil-related issue. Engine oil is the lifeblood protecting your engine, and this warning light usually indicates either critically low oil level or insufficient oil pressure. If you stubbornly keep driving, the resulting engine friction and overheating can quickly lead to cylinder scoring or bearing seizure - the repair bill for a new engine could cost you a used car. Step one is to pull over and shut off the engine immediately. Pop the hood to check the dipstick - the oil level should be between the minimum and maximum marks. If it's low, top up with the correct specification oil immediately. If the light persists after refilling, it likely indicates a failed oil pump or sensor malfunction, requiring professional towing to a repair shop. Never skip routine maintenance - checking your oil every 5,000 km helps prevent this nightmare scenario.
