What Happens If Car Engine Oil Is Insufficient?

Insufficient engine oil can lead to poor lubrication on the friction surfaces of the engine, resulting in abnormal vibrations and reduced power. Additional relevant information is as follows: 1. Engine bearing seizure, where the crankshaft bearings and bearing bushings suffer from poor lubrication leading to burning, manifests as abnormal engine vibrations until the engine stalls, after which it cannot be restarted. 2. Engine oil is a substance enhanced with additives in base oil, primarily containing anti-wear additives, detergents, dispersants, and multi-grade viscosity index improvers. Engine oil is used for lubricating internal combustion engines, with its main functions being to reduce friction and wear on moving parts and to clean sludge and varnish from the engine.
In my previous car, the engine oil was underfilled, which caused quite a few problems. Since engine oil is responsible for lubricating and cooling internal engine components, insufficient oil leads to inadequate lubrication, causing metal parts to rub against each other, resulting in increased noise and wear. Over time, the engine is prone to overheating and may even damage critical components, leading to very high repair costs. Once, I neglected to check the oil and drove a few hundred kilometers before noticing the car had poor acceleration and a sudden increase in fuel consumption. When I took it for repairs, the piston rings were found to be severely worn. Since then, I’ve developed the habit of checking the dipstick before each drive to ensure the oil level is in the middle of the marked range. Low oil levels are often caused by leaks or insufficient filling during maintenance, so regular servicing and topping up the oil are crucial for extending engine life. I recommend you check it frequently too—don’t save small money only to lose big money later.
