What are the effects of low oil viscosity?
2 Answers
The effects of low oil viscosity are: 1. Poor engine lubrication, increased wear of piston rings and cylinder walls, reduced sealing performance, leading to oil burning; 2. Poor sealing performance of valve seals, damage to the crankcase forced ventilation valve; 3. Blockage of the crankcase ventilation port, causing excessive pressure in the crankcase; 4. The oil cannot form a stable oil film on the surface of various components in the engine, resulting in a large amount of heat being generated instantly in the engine. Engine oil, also known as engine lubricating oil, consists of: 1. Base oil: The main component of lubricating oil, determining the basic properties of the lubricating oil; 2. Additives: Can compensate for and improve the shortcomings of the base oil's performance.
Using engine oil with low viscosity is not ideal. I remember one time my old car used oil with relatively low viscosity, and the engine noise was as loud as thunder. The reason was insufficient lubrication due to the low viscosity, which increased friction between parts. Over time, the wear and tear became severe, especially for critical components like piston rings and bearings, which tend to wear out prematurely. It also leads to overheating, as the cooling effect can't keep up, and the temperature rises rapidly in summer. The worst part is the compromised sealing, causing oil leaks that dirty the engine bay. I recommend regularly checking the dipstick and choosing the correct viscosity grade of oil. If you notice sluggish acceleration or the oil pressure light flickering, change the oil immediately. Always monitor your car's condition—oil that's too thin shouldn't be ignored, or you'll end up with costly repairs and compromised safety. Developing good habits is crucial.
