What are the symptoms of low oil pressure?

[VanRyan]

Symptoms of low oil pressure are as follows: 1. Increased engine noise. 2. Oil warning light comes on. Generally, the monitoring of oil pressure in engines is similar, and it can be judged mainly from the following four aspects: 1. Oil pressure warning light indication: The engine has an oil pressure sensor switch in the main oil passage of the lubrication circuit. If the oil pressure is insufficient, this information will be reported to the engine computer, and finally displayed as a red oil can-shaped fault light on the dashboard. 2. Low oil level: Insufficient oil quantity can also affect oil pressure. The oil level can be checked with the dipstick. If the level is below the minimum, it will affect the oil supply pressure. 3. Increased engine noise: The main function of oil is lubrication. If the oil pressure is insufficient, the engine will produce different noises than usual under various operating conditions. 4. Oil pressure gauge indication: The most accurate method to detect insufficient oil pressure is to monitor the oil pressure with an oil pressure gauge. For gasoline engines, the normal oil pressure is between 200kPa and 500kPa, while for diesel engines, it is between 290kPa and 590kPa.
