Do all second-generation EA888 engines burn oil?
2 Answers
Not all second-generation EA888 engines burn oil. Here are the specific reasons for oil burning: 1. Worn valve seals: Valves are used to prevent oil from leaking into the combustion chamber, but over time, they can wear out or age. Severe wear can affect the sealing of the valves, making it easy for oil to burn. 2. Excessive piston clearance: When a car is used for a long time, incomplete combustion can cause carbon deposits to accumulate on the piston rings. If not cleaned for a long time, this can widen the gap between the piston rings and the cylinder, allowing oil to flow into the combustion chamber and cause oil burning. In severe cases, it can even lead to engine seizure. 3. Driving habits: Frequent rapid acceleration and prolonged high-speed driving can easily damage the lubricating oil film, leading to poor engine lubrication and wear on certain parts, which may also result in oil burning. 4. Excessive oil level: If the oil level is too high and exceeds the maximum mark, the excess oil can easily enter the combustion chamber (due to excessive internal pressure) and form sticky carbon deposits.
I've been researching Volkswagen engines for many years. The oil consumption issue with the second-generation EA888 is indeed common but not absolute. It's mainly due to piston ring design flaws combined with sealing problems under high temperatures, leading to significant oil consumption in some vehicles. Many owners reported this between 2011 and 2015, but later batches saw improvements that significantly reduced the problem. If you have an early model like the GTI or Tiguan, the risk of oil consumption is higher. However, mid-to-late production cars, especially those made after 2014, have seen much better conditions due to design optimizations and component upgrades. Ultimately, whether oil consumption occurs also depends on usage habits and maintenance—for example, timely oil changes using synthetic oil can effectively prevent it. I recommend checking the manufacturing date and maintenance records when buying a used car. Not all vehicles are affected; the key is to conduct a thorough inspection.
