What is the normal oil pressure for a car?
1 Answers
Most car engines have a normal oil pressure range of 2.5 to 3.5 pressure units, with idle speeds ranging around 2 to 2.5 pressure units. Excessively high pressure can be very harmful. More details are as follows: 1. If the car engine oil pressure is too high, it can lead to increased fuel consumption. High-viscosity lubricants have greater viscosity, which increases the frictional resistance between component surfaces, leading to greater power loss and higher fuel consumption. 2. High car engine oil pressure affects heat dissipation. High-viscosity lubricants circulate more slowly, reducing the rate at which heat is carried away, which can cause the engine to overheat. At the same time, insufficient engine oil levels can reduce the oil pump's output or prevent it from pumping oil due to air intake, which may also lead to a drop in oil pressure.
