How many liters of engine oil can be added to the Audi A6L six-cylinder?

The six-cylinder model of this car requires 6.5 liters of engine oil. Engine oil is an essential item that every car owner needs to deal with during vehicle use, and it is often referred to as the lifeblood of the engine. If there is no engine oil in the engine, the car's engine cannot operate normally. Here is some additional information: The functions of engine oil: Inside the engine, engine oil not only lubricates but also cleans, seals, cushions, prevents rust, and dissipates heat. The function of the engine oil filter: It filters the engine oil. Without the engine oil filter, the engine oil would become very dirty after some use, which would affect the engine's lubrication and heat dissipation.
Last time I took my Audi A6L 3.0T for maintenance, the technician told me that the six-cylinder engine normally requires about 7.5 liters of engine oil. I specifically checked the manual, and it indeed states a range of 7.3-7.6 liters. However, during an actual oil change, the old oil may not be completely drained, so it's safer to pour in 7 liters first. Start the engine and let it run for a few minutes before turning it off, wait for five minutes, and then check the electronic oil dipstick. Top up as needed for the most accurate measurement. Don't overfill the oil, as excessive oil can lead to increased crankcase pressure and even cause blue smoke from burning oil. Also, remember to use 0W-20 or 5W-30 oil with VW 502 certification, otherwise, it may affect the engine warranty.
The owner of the repair shop I frequent mentioned that the Audi C8 generation's six-cylinder models generally use 7.5 liters of engine oil, with the 55TFSI's 3.0T being a typical example. Their oil change routine involves initially adding 7.2 liters, then starting the engine to circulate the oil before checking the dipstick and topping it up to the midpoint. In fact, the shop has encountered situations where the old oil wasn't fully drained, and adding the standard amount directly would exceed the upper limit. Oil levels that are too high can accelerate seal aging. Nowadays, newer models come with electronic dipsticks, and the scale bar can be accessed through the MMI menu, which is much more convenient than mechanical dipsticks.
