What are the reasons for low engine oil pressure?
2 Answers
Engine oil pressure is low due to: 1. Insufficient oil quantity; 2. Impurities in the oil; 3. Oil being too thin; 4. Damaged oil sensor; 5. Engine temperature being too high. Solutions for low engine oil pressure: 1. Check the oil level in the oil pan before each engine operation to ensure sufficient oil quantity; 2. Remove scale from the cooling system pipes; 3. Adjust the fuel supply timing; 4. Operate the engine under rated load; 5. Replace damaged pins or keys; 6. Install a filter at the oil pump suction port. Engine oil provides good lubrication for the engine, reducing friction, cleaning, buffering, and sealing the engine.
Recently, I've been experiencing low engine oil pressure issues. I remember the dashboard warning light coming on several times while driving, which made me really nervous. The most common cause of low oil pressure is insufficient oil level. You should immediately pull out the dipstick to check the oil level, and if it's below the minimum mark, top it up right away. Another critical point is the oil pump – worn or stuck pump vanes can't supply enough oil, leading to pressure drops. A clogged oil filter is also a major issue; accumulated dirt restricts oil flow, and simply replacing the filter can solve it. Additionally, low oil viscosity, such as using oil that's too thin or oil thinning due to high temperatures, can be fixed by switching back to the appropriate viscosity grade. I must remind everyone that regular maintenance is crucial. Don't wait until problems escalate to repair, as it can easily damage the engine.
