Do All Passats Burn Engine Oil?
2 Answers
Not all Passats experience engine oil burning. Only about 30% of vehicles from the same production batch may exhibit this issue. Oil burning in Passats is not unmanageable and can be entirely prevented with minimal cost and simple methods. Below is an introduction to Passat oil burning issues: 1. First, regularly add fuel additives to gasoline to maintain fuel system cleanliness, inhibit carbon deposits, and improve combustion efficiency. Second, incorporate all-in-one high-performance additives into the engine oil to enhance its properties, such as cleaning, lubrication, protection, and temperature control, thereby reducing engine contamination and avoiding wear. This addresses the issues of poor fuel and oil quality. 2. Engine oil burning is a common phenomenon, affecting models like Audi and Passat. The primary cause is the cast-iron engine. Oil burning is most noticeable during high-speed driving. Burning engine oil is as normal as burning gasoline or diesel, except that the oil consumption during normal engine operation is significantly lower than fuel consumption.
My 2012 Passat indeed burns oil, and the mechanic found it was caused by carbon buildup sticking the piston rings after disassembly. However, the newer third-generation EA888 engine has improved the oil separator and piston ring design. A friend driving a 2018 330TSI model hasn't seen any oil loss even after 60,000 kilometers. Personally, I recommend older car owners to check the dipstick every 5,000 kilometers, keep a 1L bottle of oil in the trunk, and choose an ACEA C3-certified 0W-40 oil to help reduce consumption.
