What are the symptoms of insufficient engine oil lubrication?

Engine oil lubrication insufficiency manifests as bearing bush burning and cylinder scoring. Below is an introduction to insufficient oil lubrication: Symptoms of insufficient oil: When oil is insufficient, it leads to poor lubrication on the friction surfaces of various engine components. Poor lubrication exacerbates the wear and tear of parts. Additionally, oil plays a crucial role in cooling and heat dissipation. Insufficient oil reduces the engine's cooling capacity, causing internal overheating, which can further result in bearing bush burning and cylinder scoring. Oil level control: The oil level should be within the upper and lower limits on the dipstick. Neither below the lower limit nor above the upper limit is acceptable. Excessive oil can increase engine load, affecting performance. Over time, it can also damage the engine's exhaust ventilation system, increase carbon deposits, and lead to oil burning phenomena.
I've been driving for over thirty years, and the symptoms of insufficient engine oil lubrication are all too obvious. The engine noise suddenly increases, sounding like metal clanking or grinding, which is particularly harsh when driving. There's also a significant drop in power—acceleration feels sluggish, climbing hills becomes difficult, and fuel consumption inexplicably rises due to increased friction and reduced efficiency. The temperature gauge rises rapidly, and when the oil pressure light comes on, you must pull over immediately to check, or else blue smoke might appear, or worse, the engine could seize. I ignored it once, and it resulted in severe piston ring wear, costing me thousands in repairs. My advice is to regularly check the oil level with the dipstick, keeping it between the min and max marks, and don't stretch out oil change intervals. Otherwise, the car won't last long before it's scrap—safety first.
