What are the effects of insufficient engine oil pressure in a car?

[SanJake]

The effects of insufficient engine oil pressure in a car are: inadequate lubrication, the high temperature of engine components cannot be dissipated in time, which will cause deformation of high-temperature moving parts, poor movement, and in severe cases, lead to bearing seizure and cylinder scuffing. The reasons for insufficient engine oil pressure in a car are: 1. Insufficient oil quantity in the oil pan; 2. The oil quality does not meet the requirements; 3. Fuel or water mixed into the engine oil; 4. The engine oil temperature is too high; 5. The oil filter screen is clogged or the oil inlet pipe is leaking air; 6. Insufficient oil pump pressure; 7. Severe leakage of the pressure relief valve; 8. The oil filter and main oil passage are clogged; 9. Increased leakage loss of friction pairs; 10. Oil cooling nozzle leakage.
