Why Can't Volkswagen Engine Oil Burning Be Completely Cured?
3 Answers
Because the cylinders used are mesh-like, a small amount of engine oil will seep into them during vehicle operation. If the amount of oil entering increases, it will lead to the phenomenon of oil burning, which is why Volkswagen vehicles consume a large amount of engine oil. Therefore, it is recommended that Volkswagen owners always pay attention to the usage of engine oil and replenish it promptly if it is too low. The following precautions should be taken: 1. Choose the appropriate viscosity. If an older vehicle experiences oil burning, you can appropriately choose to add higher viscosity engine oil to enhance the sealing between the engine pistons and cylinder walls. 2. Strengthen maintenance: If signs of oil burning are detected in the vehicle, frequently check the oil dipstick, regularly replace the engine oil and oil filter as required by the product manual, and use genuine oil filter spare parts. Once abnormal oil consumption is detected, take the vehicle to a repair shop for inspection.
I've been working in car repairs for a long time, and the issue of Volkswagen engines burning oil is mainly rooted in design flaws, such as defects in the piston rings and turbocharging system. The insufficient sealing of the piston rings allows oil to be sucked into the combustion chamber, while the high temperatures of the turbocharger accelerate oil consumption. Even after replacing new parts, due to engine wear and high-temperature conditions, the problem quickly recurs. Early on, manufacturers sacrificed long-term reliability in pursuit of high performance and fuel efficiency. Now, redesigning would require a complete engine overhaul, which is too costly for most car owners to bear. Therefore, the practical solution is to recommend regular oil checks and using the appropriate oil grade, but this doesn't solve the persistent issue. After all, mechanical components under high stress will always have vulnerabilities, and only daily maintenance can delay the problem.
I've been driving a Volkswagen for over a decade, and oil burning has been a persistent issue. No matter how much I repair it, nothing seems to work. I've replaced piston rings, fixed the turbo, spent thousands, but the warning light still comes on after a short highway drive. I think Volkswagen engines are too finely tuned and can't adapt to ordinary driving habits, like my frequent long-distance trips or aggressive driving, which accelerates oil consumption. The manufacturer probably didn't account for these usage scenarios during design. To fix it completely, I'd need to replace the entire engine system, which isn't cost-effective. So, I've made it a habit to check the dipstick every two weeks and top up the oil as needed. The problem keeps coming back, and it's frustrating. Buying a new car might be the easiest solution, but the financial pressure is too much, so I just have to endure it.
