What is the official explanation for Citroën's engine oil consumption?
1 Answers
Citroën's engine oil consumption is caused by the following reasons: Improper use of engine oil: Using engine oil of poor quality or with viscosity grades that do not meet the requirements. Low-quality engine oil can lead to increased wear. Additionally, engine oil with viscosity that is too low or too high can cause poor engine lubrication, increasing wear on piston rings and cylinder walls, reducing sealing performance, and resulting in oil consumption. Large piston ring gap: Excessive clearance between piston rings and cylinder walls, improper installation of piston rings, or degraded sealing performance can allow oil on the cylinder walls to enter the combustion chamber, causing oil consumption. Additionally, poor sealing performance of valve seals, damage to the Positive Crankcase Ventilation (PCV) valve, or clogged crankcase ventilation ports can increase crankcase pressure, causing oil to enter the combustion chamber along with crankcase gases and participate in combustion. Excessive engine oil: Overfilling engine oil can also lead to oil consumption. When the oil level exceeds the midpoint, excessive oil pressure can cause too much oil to splash into the combustion chamber during engine lubrication and burn.
