Is 105 Degrees Celsius Normal for Passat Engine Oil Temperature?
1 Answers
Passat engine oil temperature at 105 degrees Celsius is normal. Generally, the normal operating temperature for engine oil is around 90 degrees Celsius, but as the vehicle speed increases, the temperature will also rise, reaching approximately 100 to 110 degrees Celsius, which is still within the normal range as long as it does not exceed 120 degrees Celsius. Below are the main functions of engine oil: 1. Cooling: Engine oil carries heat back to the oil pan and dissipates it into the air, helping the radiator cool the engine. 2. Cleaning: High-quality engine oil can carry carbon deposits, sludge, and worn metal particles from engine components back to the oil pan through circulation, flushing away contaminants generated on the working surfaces of the parts. 3. Sealing: Engine oil can form a seal between the piston rings and pistons, reducing gas leakage and preventing external contaminants from entering. 4. Anti-rust and anti-corrosion: Lubricating oil adheres to the surfaces of components, preventing contact with water, air, acidic substances, and harmful gases.
