What kind of engine oil does Audi use?

Mobil 1 5W-50: 5W represents low-temperature startup performance. The principles and selection of engine oil for Audi vehicles are as follows: Principles: 50 is the viscosity index. The higher the viscosity index, the less the oil's viscosity is affected by temperature. The higher the temperature, the thinner the oil becomes. Oil selection: During use, lubricating oil is subjected to high temperatures, exhaust gases, metal catalysis, etc., which can cause the oil to oxidize and deteriorate, forming deposits such as varnish, sludge, and carbon buildup, thereby affecting the normal operation of the engine. Therefore, when the lubricating oil reaches a certain mileage or time in use, it needs to be replaced. Oil changes are generally recommended every 10,000 kilometers. If you feel that the driving environment is poor, such as poor air quality, you can change the oil at around 8,000 kilometers.
My Audi A4 has been used for seven or eight years, and I always carefully read the manual for each maintenance. Audi has quite high requirements for engine oil. New cars basically need to use 0W-20 or 5W-30 full synthetic oil, and it must have Volkswagen VW 508 00 or 502 00 certification. My old 2.0T used to use 5W-40, but now the new models with particulate filters must use 0W-20 low-ash oil. I recommend big brands like Shell Helix Ultra or Castrol Edge. The original oil used by the 4S store is actually these big brands with rebranding. Remember, regular replacement is very important. Full synthetic oil is generally replaced every 8,000 to 10,000 kilometers. In northern winters, it's best to use 0W-grade oil for smoother cold starts.
