What is the reason for the teapot-shaped light on the car coming on?

The reasons for the engine oil light coming on are as follows: 1. Excessive oil viscosity: The viscosity of the oil is closely related to its quality. Higher viscosity means better resistance to high temperatures, but this does not mean the higher the viscosity, the better. You should use an oil grade that matches your engine. 2. Pressure relief valve blockage or improper adjustment: To prevent excessive oil pressure in the lubrication system, which increases engine power consumption and causes oil leaks at sealed connections, a pressure relief valve is installed on the main oil passage or oil pump. Its function is to limit the oil pressure in the lubrication system to prevent it from exceeding the specified value. A faulty pressure relief valve can lead to abnormal oil pressure, causing the oil light to come on. 3. Insufficient oil level: If the oil level is insufficient, the oil pump's output will decrease or fail to pump oil due to air intake, leading to a drop in oil pressure. The crankshaft and bearings, as well as the cylinder liners and pistons, will experience increased wear due to poor lubrication.

When I was driving, the light on the dashboard that looks like a teapot suddenly came on. I knew it was the engine fault indicator, meaning there was an issue with the engine. I've encountered similar situations before—it could be a minor problem like the oil cap not being tightened properly or a sensor giving a false alarm, or it could be a major issue like a faulty oxygen sensor or worn-out spark plugs. After a check-up last time, it turned out to be a fuel injection problem affecting efficiency, which was fixed in time to avoid a breakdown. My advice is to slow down and pull over when the light comes on, then check the oil level and temperature gauge to see if everything looks normal. If the light stays on, head to a professional repair shop as soon as possible to scan for trouble codes. Don’t ignore it—my years of driving experience have taught me that early repairs save money and hassle while ensuring road safety, especially during long-distance drives where risks are higher.

As someone who enjoys tinkering with cars, the moment I see that teapot-shaped light come on, I know it's the MIL (Malfunction Indicator Lamp) alerting me to an issue with the engine system. Common causes include a faulty exhaust oxygen sensor, problems with the charcoal canister, or aging ignition coils. I've personally used an OBD diagnostic tool before, which indicated potential false alarms from the fuel pump or ECU. For car owners with some mechanical knowledge, keeping a simple code scanner handy for troubleshooting is advisable; otherwise, don't hesitate to take it straight to the repair shop. Regular oil changes and carbon deposit cleaning can prevent issues down the line. Engine health directly impacts fuel consumption and performance, so daily maintenance should never be neglected.

Having driven for many years, that teapot-shaped light occasionally flickers. I know it's called the malfunction indicator light, indicating an issue with the engine. It could be due to false alarms from emission system sensors or carbon buildup in the old engine. I recall one instance when the light came on due to worn spark plugs, which was resolved by timely replacement. Old-timers' advice says if the light stays on constantly, first turn off the car and restart to see if it resets; if it remains lit, get it repaired without delay. Developing a habit of regularly checking the fuel system can reduce trouble and ensure safety.
