What are the symptoms of low engine oil in a car?
2 Answers
Symptoms of low engine oil in a car include the oil warning light illuminating and engine cylinder scuffing. Oil warning light illuminating: When oil is low, it may affect the engine oil pressure, causing the oil warning light on the dashboard to illuminate. Additionally, engine noise may increase when oil is low. Engine cylinder scuffing: During engine operation, engine oil forms a protective film on lubricated components, preventing direct contact between parts and reducing wear. If friction components come into direct contact, it can lead to severe wear and generate intense heat instantly, resulting in engine cylinder scuffing or bearing seizure. Functions of engine oil: Lubrication: The primary function of engine oil is to lubricate engine pistons, bearings, and other components. Rust prevention: Engine oil helps prevent corrosion of metal components. Cleaning: It filters out debris and metal wear particles generated during engine operation through the oil filter, maintaining the cleanliness of the lubrication system.
Just helped my neighbor with this issue yesterday. If the engine oil is insufficient, that little oil can light on the dashboard will illuminate—super glaring. The engine noise becomes louder, sounding like it's clunking and wheezing, especially noticeable when climbing hills. The accelerator feels mushy, and acceleration is particularly sluggish. Sometimes blue smoke comes out of the exhaust pipe, with a burnt smell. The scariest part is the metal grinding noise under the hood—it sends chills down your spine. If you hear something like a clanging sound, don’t hesitate; shut off the engine immediately and call for help. Driving further could completely wreck the engine. Make it a habit to check the oil level with the dipstick when the engine is cold—it's the most reliable way.
