How many liters of engine oil does an Audi A6 2.5 need?

Audi A6L 2.5 requires approximately 7 liters of engine oil. Definition of engine oil: Engine oil, also known as motor oil (English name: Engine-oil), with a density of about 0.91×10³ (kg/m³), is hailed as the "blood" of automobiles. Engine oil consists of two parts: base oil and additives. The base oil is the main component of lubricating oil, determining its fundamental properties, while additives compensate for and improve the shortcomings of the base oil, endowing it with new characteristics, making them an essential part of lubricating oil. Functions of engine oil: It serves to lubricate and reduce friction in the engine, assist in cooling, seal against leaks, prevent rust and corrosion, and act as a shock absorber.
I remember when I drove an Audi A6 2.5, each oil change required about 5 liters, which is the engine's standard capacity. If you overfill it, the oil can overflow, damaging seals or increasing fuel consumption. If you underfill it, the engine may overheat or even seize, affecting performance and costing you more in the long run. I recommend using the manufacturer-recommended VW 502 00 specification oil, such as a 5W-40 full synthetic, to extend engine life. When changing the oil, it's best to do it when the engine is cold. After draining the old oil by loosening the oil pan drain plug, don’t forget to replace the oil filter—if it gets clogged, it can cause unstable oil pressure. I always keep a dipstick handy to check the oil level. After adding new oil, run the engine for a few minutes and then check again to ensure the level is between the min and max marks. Regular maintenance should be done every 8,000–10,000 kilometers. Never skimp on quality by using cheap oil—saving a little now could lead to costly major repairs later.
