How many liters of engine oil does an Audi A4L generally require?

In the currently available Audi A4L models, the fuel tank capacity is approximately 56L. For older Audi A4L models, the fuel tank capacity is about 65L. When refueling, avoid overfilling the tank as fuel may overflow when temperatures rise. Additional information regarding vehicle fuel is as follows: 1. If fuel spills, promptly wipe off any fuel that has spilled onto the vehicle body to prevent damage. Additionally, never drive until the fuel tank is completely empty. 2. Irregular fuel supply can cause the engine to misfire. Unburned fuel may then enter the exhaust system, posing a risk of damage to the catalytic converter. 3. For diesel engine vehicles, after the fuel has completely run out, you must wait at least 30 seconds after refueling before starting the engine. The subsequent starting process may take longer than usual, up to a maximum of one minute before the engine starts. This is because the fuel system must first be purged of air during the starting process.
I bought an Audi A4L 2.0T two years ago, and I've changed the engine oil myself several times since then. Experience tells me it usually takes 4.5 to 5.5 liters, and my car specifically requires exactly 5 liters. Once, at a roadside shop, the mechanic almost added 6 liters, but I stopped him immediately because incorrect oil levels can cause serious problems: too much increases resistance, leading to soaring fuel consumption or even oil leaks; too little results in insufficient lubrication, accelerating engine component wear. I check the dipstick every 5,000 kilometers to ensure the oil level is between the minimum and mid-high marks. My friends also drive A4Ls, and we remind each other to check the manual—it specifies the exact oil type required, so don't cut corners or guess. Regular maintenance not only extends the car's lifespan but also ensures peace of mind on the highway.
As someone who frequently helps others with car repairs, I've worked on many Audi A4Ls, and their oil capacity is mostly between 4.5 to 5.5 liters. For example, the standard for the post-2018 2.0T engine is 5 liters. When changing the oil, it's essential to drain all the old oil completely, add new oil, start the engine, and then check and adjust the oil level using the dipstick to avoid overfilling or underfilling. Overfilling can cause the oil to foam, reducing its lubricating effectiveness, while underfilling can accelerate bearing wear or even lead to engine stalling. I recommend owners use the correct oil type, such as full synthetic 0W-40, and check the oil level every six months to prevent aging and leaks. Though this seems minor, it can save the trouble of major engine repairs. Developing this habit naturally leads to more stable car conditions.
