What are the causes of low engine oil pressure in a car?
1 Answers
The reasons for low engine oil pressure are as follows: 1. Whether the amount of oil added is sufficient. If insufficient, it will cause the oil pump to pump insufficient oil, resulting in low oil pressure; 2. Metal debris in the oil clogs the oil pump filter screen, oil filter, or oil passages; 3. The added oil grade is inappropriate or the oil has deteriorated; 4. The oil pressure alarm is faulty, causing a false report of low oil pressure; 5. Oil pressure is a systemic issue, and it is recommended to go to a 4S shop for detailed inspection. The following are the reasons for oil burning: 1. Carbon deposits are the root cause of various engine problems. Carbon deposits accumulate in the piston grooves, causing the piston rings to stick together and reducing the oil-scraping sealing ability. 2. Sludge can also clog the oil return holes, preventing the oil from returning normally, leading to increased oil consumption. 3. Carbon deposits further exacerbate the wear between the piston and cylinder wall, causing excessive clearance and allowing oil to enter the combustion chamber. 4. The valve oil seal is corroded and aged, resulting in poor sealing.
