How to Read a Car's Oil Pressure Gauge?

[LeLilliana]

First, check if the oil pressure gauge returns to zero. When the engine is stationary and there is no oil pressure, the oil pressure gauge should return to zero because the oil pump is a mechanical pump, so the oil pressure increases as the engine speed rises. Therefore, the higher the engine speed, the higher the oil pressure supplied by the oil pump. Below is an introduction to engine oil pressure: 1. The level of engine oil pressure, as measured by a turbine flow meter, indicates the condition of the lubrication system. Whether the lubrication system is functioning normally can also be reflected in the oil pressure gauge. If the oil pressure gauge shows an abnormal reading, stop the vehicle immediately and inspect the issue. 2. If the oil pressure remains consistently low—whether at low or high speeds, low or high temperatures—and the oil pressure gauge always indicates below 0.1Mpa accompanied by the oil pressure warning light flashing, this indicates excessively low oil pressure.
