What are the symptoms of insufficient engine oil in a car?
2 Answers
Performance of insufficient engine oil in a car: Lack of engine oil will result in insufficient lubrication, leading to dry friction, high water temperature, valve noise, and knocking sounds. In severe cases, it can cause cylinder scuffing and damage mechanical components of the engine, such as the crankshaft and crankshaft bearings. The engine oil level should be maintained at the middle line of the dipstick's limit area. When checking, make sure to park the car in a safe and stable place. The main functions of engine oil: Lubrication between the piston and cylinder, as well as between the main shaft and bearings, involves rapid relative sliding. To prevent excessive wear of parts, an oil film needs to be established between the two sliding surfaces. A sufficiently thick oil film separates the surfaces of the relatively sliding parts, achieving the purpose of reducing wear.
I've seen plenty of signs of insufficient engine oil. After driving for 20 years, I know that forgetting to top up oil often leads to trouble. The most obvious indicator is the constant illumination of the oil pressure warning light on the dashboard, like a little figure complaining. The engine noise becomes noticeably louder, with a distinct tapping sound - especially during acceleration or uphill driving. You'll also feel a loss of power, as if the car is struggling to move forward, like dragging its feet. If not addressed promptly, rising oil temperature and engine overheating can cause bearing wear or piston seizure, potentially costing thousands in repairs. I've learned my lesson now - every month I check the oil level with the dipstick to ensure it's between the minimum and maximum marks, topping up when necessary to prevent issues. Developing this simple habit protects your engine's lifespan and gives peace of mind on long drives.
