What are the reasons for the Peugeot 3008 burning engine oil?

The reasons for the Peugeot 3008 burning engine oil are as follows: 1. Generally, engine oil burning is caused by excessive clearance between the piston rings and cylinder walls, improper installation of piston rings, or reduced sealing performance, allowing oil on the cylinder walls to enter the combustion chamber, leading to oil burning. 2. Additionally, poor sealing performance of the valve seals, damage to the crankcase forced ventilation valve (PCV), or blockage of the crankcase ventilation port causing excessive pressure in the crankcase can all result in oil entering the cylinder along with crankcase gases and participating in combustion. Relevant information about engine oil is as follows: 1. Engine oil, also known as engine lubricant (English name: Engine-oil), has a density of approximately 0.91×10³ (kg/m³) and serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption in the engine. 2. Engine oil consists of two parts: base oil and additives. The base oil is the main component of lubricating oil, determining its basic properties, while additives compensate for and improve the shortcomings of the base oil, imparting certain new properties, making them an important part of lubricating oil.
My Peugeot 3008 occasionally burns engine oil after prolonged use, and there are several main reasons for this. Piston ring wear is the most common issue, as the ring gap increases with long-term use, allowing oil to leak into the combustion chamber and burn off. This is related to high-speed driving or frequent stop-and-go conditions. Another reason is the aging of valve stem seals; the rubber material hardens and cracks, causing oil to seep down and increase consumption. If the car is turbocharged, damaged or poorly sealed turbo oil seals can lead to oil leakage and burning, especially when the engine overheats. Additionally, poor-quality oil or extended maintenance intervals can cause sludge buildup, clogging oil passages. I recommend regularly checking the oil dipstick level and changing the oil promptly to avoid engine cylinder scoring, increased fuel consumption, and power loss. If issues arise, it's best to visit a professional workshop for diagnosis to prevent minor problems from turning into major repairs.
