What Does Insufficient Oil Pressure Mean?

[LeDerek]

When the engine oil pressure is insufficient, the main reasons are as follows: 1. The engine oil storage is too low, causing the lubrication system to have no oil or insufficient oil: refill the oil in time to ensure sufficient oil storage. 2. The oil is dirty or too viscous, preventing the oil pump from effectively sucking and pumping the oil: the oil needs to be replaced promptly. 3. The oil is too thin or becomes thin due to high engine temperature: thin oil may leak from the gaps between the engine's friction pairs, leading to insufficient oil pressure. It is necessary to replace the oil or repair the cooling system in time. 4. The oil pressure sensor is damaged: the normal oil pressure range should be maintained between 150～350kPa.
