Volkswagen cars do indeed burn engine oil. The reasons why Volkswagen cars burn engine oil are as follows: 1. Oil separator: The oil separator often fails, leading to ineffective oil-water separation of oil vapor. Additionally, the seal between the camshaft end cover and the cylinder block is not tight due to insufficient strength of the plastic end cover, causing oil leakage. 2. Engine oil: In turbocharged models, engine oil is needed for cooling, so the oil evaporates when cooling the turbocharger. 3. Driving habits and fuel quality: During driving, driving habits and fuel quality can also cause the engine to burn oil. Rapid acceleration can lead to incomplete combustion of fuel in the engine, resulting in carbon deposits. Poor fuel quality can also cause carbon deposits after combustion. There are many factors that contribute to oil burning, which is why some car owners experience it while others do not.

As someone who has owned two generations of Volkswagen Passats, I must say this issue really depends on the specific model and year. The older second-generation EA888 engines did commonly experience significant oil consumption, especially after exceeding 80,000 kilometers - keeping spare oil in the trunk became a running joke among owners. However, the third-generation engines post-2015 improved piston ring design and upgraded the oil separator. My current Magotan B8 has covered 40,000 kilometers with barely any movement on the dipstick. In fact, all turbocharged cars have minimal oil consumption - as long as it doesn't exceed 0.5 liters per 5,000 kilometers, it's normal. If you notice blue smoke from the exhaust or need to top up oil every 1,000 kilometers, that definitely indicates problems with piston rings or valve stem seals.

Last week, I just helped a neighbor inspect a Touareg with oil consumption issues. There are three main causes of oil burning in Volkswagen turbocharged engines: carbon buildup on piston rings causing sticking is the most common, as the high-temperature design of German cars tends to let sludge block the oil return holes; secondly, failure of the oil separator, where oil vapor isn't recycled and directly enters the combustion chamber; and aging and hardening of valve stem seals, especially in cars over seven years old. The solutions aren't complicated: for newer cars, using VW502-certified 0W40 full synthetic oil can help alleviate the issue. For older cars, it's recommended to dismantle and clean the piston rings or replace them with improved separators. A local repair shop can handle this for just over two thousand, which is half the price of a dealership.

Many people don't realize that oil burning can be categorized as genuine or false. Genuine oil burning indicates mechanical failure, while false oil burning actually refers to excessive oil evaporation. Owners of older Bora models are well aware that Volkswagen's oil-gas separation system wasn't finely designed, causing more engine oil to vaporize and burn when the engine runs hot. The newly launched EA211 Evo engine now adopts dual-stage separation technology, which has significantly improved oil consumption control. The key is regular maintenance - full synthetic oil should be changed every 7,500 kilometers. Don't trust the 15,000 km oil change interval recommended by dealerships, as that's practically murder for turbocharged engines.
