What type of oil should be used for Audi A3 maintenance?

[MaciFitz]

Audi A3 maintenance uses 5W-40 type oil. Increased fuel consumption: When adding oil to the engine, the oil level should be between the upper and lower limits on the dipstick. If too much oil is added to the engine, the oil volume will expand as the engine temperature rises, increasing the pressure in the oil chamber and the running resistance. This can lead to reduced vehicle power and increased fuel consumption. Overfilling oil: If too much oil is added, the crankcase vent pipe may leak oil, and the increased pressure in the crankcase can cause the oil seals to loosen under the oil pressure, leading to oil leaks. Heat dissipation: Overfilling oil can affect engine heat dissipation.
