The hazards of insufficient engine oil in a sedan: 1. Insufficient oil can cause cylinder scoring; 2. Too little oil can lead to poor lubrication, causing wear and tear on engine components, while too much oil can increase operational resistance. Engine oil, also known as engine lubricant, serves multiple functions such as lubrication and friction reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion prevention, and shock absorption, earning it the reputation as the 'blood' of a car. Engine oil consists of two main components: base oil and additives. The base oil is the primary component of the lubricant, determining its fundamental properties, while additives compensate for and improve any deficiencies in the base oil's performance, making them an essential part of the lubricant.
I've personally experienced the issue of low engine oil! Insufficient lubrication causes increased friction between parts, making the noise unbearably harsh. My car had this exact problem last time, and fuel consumption shot up by over half a liter! Prolonged operation can lead to piston ring and cylinder liner scuffing, with the oil warning light flashing constantly. The most annoying part is the degraded cooling performance – engine overheating may cause complete breakdown. Always check the dipstick regularly, maintaining oil level between MIN and MAX marks. If oil is low, don't push it – immediately top up with the same specification oil or visit a repair shop for proper maintenance.
Buddy, you've asked the right question! Insufficient engine oil is the most damaging to your car. The crankshaft bearings and camshaft end up grinding directly, not only causing loud noises while driving but also doubling the risk of cylinder scoring. Just last month, my neighbor's car had this issue—the piston rings seized up, costing 8,000 yuan for a major repair! Engine oil also has a cleaning function; if it's low, carbon buildup increases rapidly, and the catalytic converter is more prone to poisoning. Remember to check the dipstick three minutes after turning off a warm engine—cold measurements aren't accurate. Being 200 milliliters short is fine, but if it's below the minimum mark, you need to address it immediately.
