Turbocharged vehicles generally have a slight oil burning issue, which is normal, while naturally aspirated vehicles do not burn oil. Additional information: Oil-burning models: The cylinder walls of German car engines are designed differently from other vehicles. German cars have grooves or grids on their cylinder walls that can hold a certain amount of engine oil, providing lubrication during high-speed operation. However, during low-speed driving or in traffic congestion, the oil in these grids may burn off, which is why German cars tend to burn oil. Shell Oil introduction: Formed in 1907 through the merger of Royal Dutch Petroleum Company and The Shell Transport and Trading Company. Today, Shell Group operates in over 130 countries with nearly 100,000 employees, making it one of the largest energy companies in the world.

I've had my 2020 A6L for almost two years now, with about 60,000 kilometers on it. The oil consumption issue isn't really noticeable. I usually get it serviced every 7,500 kilometers, and the oil level is still within the normal range when it's time for an oil change. My friend's older 2015 A4, on the other hand, often needs to top up oil midway, but he says it improved a lot after switching to the third-generation EA888 engine. However, the mechanic also reminded me that if you drive aggressively or exceed the maintenance interval, any German car could consume more oil. I've developed a habit of checking the oil level with the dipstick before long trips, and using the manufacturer-recommended 0W-20 full synthetic oil actually results in less consumption. In the end, sticking to the maintenance schedule is key, and my car is in great shape so far.

Having run an auto repair shop for over a decade, I've noticed that maintenance orders for 2020 Audi models rarely report oil consumption issues these days. With older Audi models, burning one liter of oil every 5,000 kilometers was considered normal, but the new engines have significantly improved sealing. The most notable upgrades are the redesigned piston rings and updated crankcase ventilation system (PCV), which greatly reduce the chance of oil entering the combustion chamber. That said, I've encountered a few cases where owners used substandard oil to save money, resulting in blue smoke appearing by 70,000-80,000 km. My advice: stick to factory-recommended service intervals, check oil level every 10,000 km, and inspect the PCV valve first if abnormalities occur. When properly maintained, this generation of Audi engines shouldn't give owners oil-related headaches.

I've been driving my A4L for commuting for exactly three years, covering 40 kilometers daily. Initially, I was quite concerned about the oil consumption issue, but in actual use, I found the worry to be unnecessary. Now at 40,000 kilometers, I hardly need to add any oil between service intervals. The third-generation EA888 engine has been optimized in thermal management, with noticeable improvements especially during cold starts. However, it's advisable to develop a habit of checking, such as pulling the dipstick after an overnight stop, with the oil level ideally in the middle of the scale. Among fellow car owners, when excessive consumption is encountered, it's mostly due to valve stem seals or turbocharger issues, but cases with the 2020 model are really rare.

Just helped my neighbor change the oil in his 2020 Q5 over the weekend. The car has 70,000 kilometers with full 4S dealership maintenance history. When draining, the oil level was completely sufficient, and borescope inspection showed no cylinder wall scoring or sludge. Discussing with fellow mechanics who specialize in German cars, the general feedback is that this generation of Audi has reduced oil consumption issues by over 80%. Prevention techniques are actually simple: avoid frequent full-throttle acceleration, especially when the engine is cold; remember to let turbocharged engines idle for 1 minute before shutting down; add a bottle of fuel system cleaner every two tanks of gas to remove carbon deposits. As long as these three points are followed, oil consumption anxiety can basically be eliminated.
