How to Solve Volkswagen Engine Oil Burning Issue?
2 Answers
If an older vehicle is experiencing engine oil burning, you can appropriately choose to add higher viscosity engine oil to enhance the sealing between the engine pistons and cylinder walls. If signs of engine oil burning are detected in the vehicle, frequently check the oil dipstick and replace the engine oil and oil filter regularly as required.
I've encountered the issue of oil burning in Volkswagen cars several times, which is indeed quite common, especially in older models. Oil burning usually occurs due to worn piston rings or aging valve stem seals, causing oil to seep into the combustion chamber and burn off. Addressing this requires a step-by-step approach. First, monitor the oil consumption by regularly checking the dipstick. If the oil level drops significantly every thousand kilometers, it's time to take it seriously. It's recommended to start by replacing the piston rings and valve stem seals, as these are common issues in Volkswagen engines, particularly the EA888 series. Then, inspect the PCV valve system—if it's clogged, it can cause unstable pressure and worsen oil burning. In cases of severe wear, an engine overhaul might be necessary, but this is costly, so budget accordingly. Regular maintenance is crucial—use high-quality oil and change filters on time to effectively delay this problem. The key is not to delay, as it can damage the catalytic converter, increase fuel consumption, or even lead to engine failure. It's best to get a professional diagnosis early to prevent small issues from becoming major problems.
