What does the yellow water can light on the dashboard mean?

The yellow water can light on the dashboard: It is normal if it lights up when you just start the car. However, if it stays on while driving, it indicates an engine fault, and you should take the car for inspection and repair. The water can symbol on the car dashboard is the engine oil indicator. Reasons for the engine oil indicator light to turn on include: 1. Insufficient engine oil: The oil pump's output decreases or fails to pump oil due to air intake, leading to a drop in oil pressure and triggering the oil light alarm; 2. Faulty oil pressure switch (oil sensor); 3. Fault in the wiring between the oil pressure switch and the dashboard; 4. Dashboard malfunction; 5. Insufficient pressure in the engine's internal lubrication system.
Last time I went on a long-distance trip, I also encountered this situation. That little yellow oil can light scared me. This is the oil pressure warning light, most likely indicating low oil level or a system issue. I immediately pulled over, popped the hood to check the dipstick, and sure enough, the oil level was at the minimum mark. Luckily, I had a spare bottle of engine oil in the trunk. After adding about half a bottle, the light went off. This incident reminds us to check the oil level every month, especially for cars over ten years old. Engine oil is the lifeblood of your engine - driving with the red warning light on could destroy the engine in minutes, and repairs could cost tens of thousands of yuan.
I've seen this yellow oil light countless times. When repairing cars, nine out of ten cases are related to engine oil issues—either insufficient oil level or clogged oil filter causing low oil pressure. Last time, a customer ignored the yellow light and drove for two months before coming in, resulting in engine seizure. I recommend immediately pulling over to a safe spot to check the dipstick. If the oil level is normal, you should visit a repair shop to test the oil pressure. Older vehicles require extra caution, as oil pump wear and leaks are particularly common. Also, a reminder for friends in northern regions: using the wrong oil viscosity in winter can also trigger this warning light.
That's the engine oil pressure warning light, indicating an issue with the engine lubrication system. There are three common causes: low oil level, a clogged oil filter restricting oil flow, or a faulty oil pump. Immediate action is required - don't assume a yellow light is less severe than a red one and continue driving. I've seen drivers travel over 100 kilometers like this, ultimately spending 30,000 yuan on a new engine. A simple method is to turn off the engine, wait five minutes, then pull out the dipstick, wipe it clean, reinsert it, and check if the level is between the min-max marks.
