What are the symptoms of insufficient car engine oil?
2 Answers
Symptoms of insufficient engine oil include: high water temperature, valve noise, knocking sounds, and in severe cases, cylinder scuffing which can damage mechanical components of the engine such as the crankshaft and crankshaft bearings. Below is an introduction to related content: 1. Engine oil performs multiple functions within the engine, including lubrication, cleaning, sealing, and cooling. If the engine operates without oil, it can be rendered useless within minutes. 2. Engine oil, also known as motor oil or engine lubricant, is a substance enhanced with additives in a base oil. It mainly contains anti-wear additives, detergents, dispersants, and multi-grade viscosity index improvers. Engine oil is used for lubricating internal combustion engines.
I've been driving for many years and noticed that when the engine oil is insufficient, the engine first becomes extremely noisy, with a sound like metal grinding, especially noticeable at idle, and the car will shake noticeably. The oil pressure warning light on the dashboard will come on to alert you—don't ignore it. When accelerating, you'll feel a lack of power, the throttle response will be sluggish, and fuel consumption will inexplicably increase, likely due to insufficient lubrication increasing engine strain. In severe cases, the engine may overheat, with the dashboard temperature gauge spiking. Prolonged neglect can lead to piston ring wear or cylinder damage, resulting in extremely high repair costs. I recommend developing a habit of regular checks, such as inspecting the dipstick level once a month when the engine is cold, ensuring it stays within the safe range. Otherwise, discovering the issue too late and adding oil won't help—safety on the road comes first.
