How much engine oil should be added to an Audi each time?

Audi cars require approximately 4.8 liters of engine oil per refill. Engine oil consists of two components: base oil and additives. The base oil is the main constituent of lubricating oil, determining its fundamental properties, while additives serve to compensate for and enhance any deficiencies in the base oil's performance. Functions of engine oil: The primary functions of engine oil are lubrication, cleaning, and heat dissipation. In fact, many parts of a vehicle use oil, but the oil that needs to be changed every 5,000 kilometers refers specifically to engine oil. Most people generally use semi-synthetic or fully synthetic oils, with conventional oil being less commonly used. Conventional oil is typically employed in agricultural machinery, three-wheeled vehicles, and motorcycles. Oil change intervals: Conventional oil: 5,000 kilometers, Semi-synthetic oil: 7,500 kilometers, Fully synthetic oil: can go up to 10,000 kilometers before requiring maintenance.
The first time I drove an Audi, I was completely confused about the engine oil quantity. After checking the owner's manual myself, I realized the amounts vary significantly between models - for example, the A4 typically requires 4 to 5 liters, while the Q7 series might need around 6.5 liters. Never guess - the oil level must stay between the MIN and MAX marks on the dipstick: overfilling can cause leaks and damage seals, while underfilling leads to engine overheating and wear. I remember one DIY attempt where I only added 4 liters, resulting in loud engine noises on the road that forced me to top up immediately. Now I recommend beginners always check the dipstick when the engine is cold and parked, referring to the manual's specific data. Regular maintenance is crucial too, as aged oil loses lubrication efficiency. Always use the recommended viscosity (like 5W-30 or 0W-40 listed in your manual) and avoid cheap oils. Proper oil quantity improves driving safety, fuel efficiency and reduces wear - I've developed a monthly checking habit that's saved me considerable repair costs.
I've encountered many Audi owners asking about this during car repairs. Simply put, the amount depends on the model and engine size. Basic models like the A3 require about 4 to 4.5 liters, while high-end models like the S8 can take over 8 liters. When adding oil, always ensure the engine is cool before checking the dipstick: the middle position is ideal—add a little if it's low, and remove excess if it's high. Overfilling increases oil pressure, which can damage components; insufficient oil can cause cylinder scoring and smoke. It's recommended to use genuine oil, with reliable brands like Shell or Castrol. Don't tinker with it yourself unless you're knowledgeable; otherwise, take it to a professional shop for testing to be safer. Regular oil change intervals must also be followed, as Audi engines are sensitive to oil quality. Exceeding mileage without changing the oil accelerates wear. I've seen owners who used the wrong oil spend thousands more on repairs—it's not worth it.
