Engine oil pressure anomaly analysis

The main causes are: oil pressure, mechanical conditions of the car, oil factors

♂The pressure fluctuates greatly. (The oil pump wears out, the pressure gauge is faulty, the filter is blocked by dirt, the oil suction pipe is exposed to the oil surface, and the oil suction position is high.)

The amount of oil is insufficient, and the main bearing has a large clearance to the radial direction.

The pressure is low. (The oil intake height is too high, the friction secondary temperature is too high, and air is mixed in the oil passage)

♂The vehicle runs for a long time and the viscosity of the lubricating oil is low.

The oil circuit is poorly sealed and lubricated.

The lubricating oil is too cold and too viscous.

♂ Lubricating oil sludge is deposited and has poor cleanability.

The oil of the sump oil is expensive.

♂ Poor evaporative, burning engine oil.

The oil of the sump oil is expensive. The fuel is diluted.

♂ Lubricating oil viscosity is too low.

♂ Lubricating oil has poor anti-foaming properties.
