What are the symptoms of low engine oil?

Symptoms of low engine oil include: First, the oil warning light will illuminate. If the situation is severe, the vehicle may start to shake. At this point, you should immediately pull over and turn off the engine to avoid the risk of engine failure, and seek professional assistance. Insufficient oil leads to inadequate lubrication, which can cause high engine temperature, valve noise, knocking sounds, and in severe cases, cylinder scuffing, damaging mechanical components such as the crankshaft and crankshaft bearings. An engine is a machine that converts other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc.
I've been driving for over 20 years and have experienced several instances of low engine oil. The symptoms are very obvious: the engine noise becomes particularly loud, especially when accelerating, sounding like knocking with a roaring noise; the oil light on the dashboard will definitely come on, which is a warning signal; fuel consumption will be much higher than usual because insufficient lubrication increases friction, reducing efficiency; when accelerating, the car feels sluggish, and the throttle response is slow. In cases of severe oil shortage, the engine may overheat and smoke, and if left unchecked, it can lead to engine seizure or major repairs, which can be quite costly. Every time I refuel, I check the dipstick to ensure the oil level is between min and max, and I change the oil every 5,000 kilometers to prevent these symptoms. Remember, regular checks are key to saving money and peace of mind—don't wait until there's a problem to regret it.
