What is the normal temperature range for car engine oil?
1 Answers
Car engine oil temperature is normal between 70 to 90 degrees Celsius. The reasons for excessively high engine oil temperature are: 1. Insufficient oil quantity or excessively high oil level can easily lead to overheating; 2. Malfunction of the oil pump or insufficient pumping volume can cause inadequate oil pressure and poor cooling; 3. Blockage of the oil cooler prevents normal cooling due to insufficient oil pressure; 4. Clogged oil filter allows impurities to enter the main oil channel through the bypass valve, accelerating engine wear; 5. Excessive bearing clearance leads to excessive oil leakage; 6. Overloaded engine causes excessively high coolant and oil temperatures; 7. Overly tight engine assembly; 8. Use of incorrect or inferior quality engine oil.
