The typical answer is synthetic 5W-40 oil that meets VW 502.00 specifications. However, the exact oil can vary by engine variant and market, so always verify with the owner's manual or the engine code for your car.
Engine options and typical specs
Note: The 2006 Audi A3 was offered with several gas and diesel engines across markets. The oil specification depends on the specific engine. The following reflects common baselines for this model year.
- Gasoline engines (e.g., 2.0L FSI and 1.6L variants): synthetic 5W-40 oil that meets VW 502.00 is typically recommended. Some climates or service intervals may allow 5W-30 if approved by VW/Audi, but 5W-40 is the safer default.
