Should the Audi Q3 use 5W30 or 5W40 engine oil?

[DelJaxson]

The Audi Q3 should use 5W40 engine oil. Below are relevant introductions about engine oil: 1. Increased fuel consumption: When adding engine oil, the oil level should be between the upper and lower limits on the dipstick. If too much engine oil is added, the 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. 2. Overfilling engine oil: If too much engine oil is added, the crankcase breather pipe may leak oil. The increased pressure in the crankcase can cause the oil seal to loosen due to the oil pressure, leading to oil leakage. 3. Heat dissipation: Overfilling engine oil can affect the engine's heat dissipation.
