What are the symptoms of insufficient engine oil?
2 Answers
The symptoms of insufficient engine oil are: 1. Increased noise; 2. Accelerated engine wear; 3. Abnormal vibration and reduced power; 4. Increased fuel consumption. Engine oil plays roles in lubricating and reducing friction, assisting in cooling, sealing against leaks, preventing rust and corrosion, and cushioning shocks. Effects of overfilling engine oil: 1. Impacts engine performance; 2. Causes carbon buildup; 3. Oil additives may reduce the conversion efficiency of the catalytic converter. Precautions for changing car engine oil: 1. Drain oil when hot for better fluidity; 2. Fill to the dipstick mark; 3. Select oil based on driving conditions, frequency, and engine requirements.
Insufficient engine oil can cause some noticeable symptoms. With over a decade of driving experience, I've encountered this issue before. Firstly, the engine may produce abnormal noises, resembling metal friction sounds, especially noticeable during acceleration. This happens because inadequate oil levels lead to insufficient lubrication of internal engine components, causing rough operation. Secondly, the oil pressure warning light on the dashboard may illuminate, indicating low oil pressure. If ignored for too long, the engine temperature tends to rise, potentially triggering an overheating alarm. Once, I overlooked it and noticed increased fuel consumption and reduced vehicle power. Upon checking with the dipstick, the oil level was indeed much lower. It's advisable to develop a habit of regularly checking oil levels and topping up as soon as a shortage is detected—don't delay too long, or severe wear could lead to expensive repairs. Fellow car enthusiasts often say that addressing minor issues promptly can save big money.
