As we explore the oil consumption issue within the EA888 engine series, it is essential to recognize the significance of these engines in the automotive landscape. Their widespread adoption and exceptional performance make addressing the oil consumption issue crucial for owners and enthusiasts alike.
The Oil Consumption Issue
The oil consumption issue has emerged as a concern with the introduction of the second generation EA888 engines. This issue manifests as an excessive consumption of engine oil, requiring frequent top-ups and potentially leading to low oil levels over time.
One of the primary symptoms owners may encounter is the need to add oil between regular oil change intervals. While some oil consumption is normal for any engine, many 2nd generation EA888 engines went way beyond that. In fact, owners have reported oil consumption of more than a quart of oil per 1000 miles.
The consequences of excessive oil consumption should not be underestimated. Insufficient oil levels can lead to inadequate lubrication, potentially resulting in accelerated wear and tear of engine components. In severe cases, it may even lead to catastrophic engine failure, necessitating costly repairs or engine replacements.
How do you fix this issue? By replacing the piston rings with the newer, updated ones. Unfortunately, that is the only solution available for EA888 engines that were affected the most. Regular oil changes, use of quality engine oil and oil filters can postpone any serious damage.
Causes of Oil Consumption in EA888 Engines
Excessive oil consumption in 2nd gen EA888 engines can be attributed to two significant factors — piston ring design and the crankcase ventilation system. Let’s delve deeper into each of these factors:
Piston Ring Design
The piston rings in an engine play a crucial role in maintaining proper oil control. They create a seal between the piston and the cylinder wall, preventing oil from entering the combustion chamber while ensuring efficient lubrication. However, in the 2nd generation of the EA888 engine series, the piston ring design had certain shortcomings that contribute to increased oil consumption.
- Wear — Over time, piston rings can experience wear due to the high temperatures and pressures they endure during engine operation. This wear can compromise their ability to create an effective seal, resulting in oil consumption. If the piston rings become worn or damaged, they may allow oil to pass into the combustion chamber, leading to higher oil consumption.
- Improper Installation — During engine assembly, proper installation of piston rings is crucial to ensure their optimal performance. If the piston rings are not installed correctly, they may not provide a tight seal, allowing oil to bypass and contribute to oil consumption.
- Design Shortcomings — The design of the piston rings themselves can also play a role in oil consumption. Certain iterations of the EA888 engine series may have had piston ring designs that were not optimized for controlling oil consumption. This could be due to various factors, including manufacturing processes, material choices, or engineering considerations.
Addressing the piston ring design issue typically involves implementing updated piston ring designs that address the shortcomings of previous iterations. The new designs aim to improve the sealing properties of the rings, minimize oil bypass, and reduce oil consumption in affected EA888 engines.
Crankcase Ventilation System
The crankcase ventilation system is responsible for regulating the pressure and removing gases, including blow-by gases, from the engine crankcase. This system helps maintain a controlled environment within the engine and prevents pressure build-up that can adversely affect engine performance. However, issues with the crankcase ventilation system can lead to increased oil consumption in certain EA888 engine models.
- PCV Valve — The Positive Crankcase Ventilation (PCV) valve is a critical component of the crankcase ventilation system. It ensures the proper flow of gases and prevents excessive pressure buildup in the crankcase. If the PCV valve malfunctions, becomes clogged, or fails to operate correctly, it can disrupt the balance of pressure, leading to increased oil consumption.
- Clogged Ventilation System — Over time, the crankcase ventilation system can accumulate debris, sludge, or carbon deposits, resulting in restricted airflow. A clogged ventilation system hinders the proper removal of blow-by gases and increases crankcase pressure, which can contribute to higher oil consumption.
Addressing the crankcase ventilation system issue typically involves inspecting and cleaning the system, ensuring the PCV valve is functioning correctly, and removing any obstructions or deposits that may impede the proper flow of gases.
Manufacturer’s Response and Solutions
As expected, Volkswagen has initially refused to admit that there is anything wrong with their engines. However, the overwhelming pressure from customers all around the world has forced them to finally take action. To address the oil consumption issue in the EA888 engine series, the manufacturer, Volkswagen Group, has taken steps to provide solutions and support to affected owners.
- Recalls and Service Campaigns —In response to the oil consumption issue, Volkswagen Group has initiated recalls and service campaigns for specific EA888 engine models. These campaigns aim to rectify the underlying causes of excessive oil consumption and provide necessary repairs or replacements to affected components. It is important for owners to check with their authorized service centers or dealerships to determine if their specific vehicle is included in any recalls or service campaigns.
- Updated Piston Rings — As part of the solution, Volkswagen Group has developed updated piston rings designed to improve oil control and reduce oil consumption. These new piston rings feature enhanced sealing properties and address the shortcomings of previous designs, providing a more effective solution to the oil consumption issue.
- Revised Crankcase Ventilation Systems — The manufacturer has also made revisions to the crankcase ventilation systems in certain EA888 engine models. These revisions aim to optimize the functionality of the system, ensuring proper pressure regulation and reducing the potential for increased oil consumption.

My daughter’s 2013 AllRoad bagan using a quart of oil ever fuel tank fill up! I pulled the oil fouled plugs, drained the crankcase and poured Berryman’s B-12 into the cylinders. I left the drain plug out and caught the B-12 in a clean oil drain pan. After 6 or 7 bottles it finally started coming out almost clear. I finished the oil change and installed new spark plugs. She now gets over 3000 miles before having to add a quart of oil.
