What does a red oil can on the car dashboard mean?

When a red oil can icon appears on the car dashboard, this warning light indicates severe engine oil blockage or insufficient oil level. In this situation, you should immediately stop the vehicle and preferably have it towed to a 4S shop for repair. Here are the major functions of engine oil: 1. Lubrication and friction reduction: Engine oil forms an oil film between two sliding surfaces, preventing direct metal-to-metal contact and ensuring smooth operation of components. 2. Cleaning and dispersion: High-quality oil can flush away surface contaminants through oil circulation, absorbing tiny metal particles in the engine which are then scraped down to the oil pan by piston rings. 3. Cooling: During engine operation, oil absorbs heat from high-temperature areas and carries it away, assisting in component cooling. 4. Sealing: Creates an oil film seal between piston rings and cylinders to prevent combustion gases from leaking into the crankcase. 5. Rust and corrosion prevention: Good oil adheres to component surfaces, protecting them from contact with air, acidic substances, and harmful gases, thus preventing corrosion. 6. Shock absorption: When cylinder pressure increases suddenly, the oil lubricates bearings to cushion the impact loads on pistons, piston rings, connecting rods and crankshaft bearings.
I personally witnessed the red oil can light on the dashboard illuminate, which is an urgent warning for low engine oil pressure. Last month while driving to the suburbs, the light suddenly flashed, making me nervous, so I immediately pulled over and turned off the engine. If I had continued driving, the insufficient oil pressure would have caused excessive friction and overheating of internal engine components, potentially leading to bearing seizure or even complete engine failure—repairs for which could cost thousands. Possible causes include low oil levels due to leaks, a faulty oil pump, or a clogged oil passage. I popped the hood and checked the dipstick, confirming the oil level was indeed low. I grabbed spare oil from the trunk and topped it up. After restarting, some warning lights disappeared, but I still took it to a professional repair shop for a thorough inspection, where they found a small crack in the oil pan. My advice to all car owners: if this light comes on, stop immediately to check oil levels. If topping up doesn’t resolve it, seek professional repairs. Also, regular oil changes every 5,000 kilometers can prevent such issues.
As a new driver who hasn't been driving for long, I was sweating with fear when I first encountered that red oil can warning light in my car. A friend explained that it indicates the engine oil pressure is too low, most likely due to insufficient oil or a leak problem. If ignored and driven hard without oil lubrication, parts would overheat and seize, destroying the engine. That time, I immediately pulled over and turned off the engine after exiting the highway, checking the dipstick to find the oil level had dropped significantly. I topped up with some spare oil but the light remained on, so I didn't dare move the car and called a tow truck to the shop. It turned out to be a clogged oil filter screen, costing only three hundred to fix. Now I've learned my lesson: always check the oil level before hitting the road, keep emergency oil in the car, because safety is more important than anything. Remember to address it promptly to prevent major disasters.
