The default answer is to use a fully synthetic engine oil that meets Volkswagen Group specifications, typically VW 504 00 or VW 507 00, with a common viscosity of 5W-30. The exact requirement depends on your engine variant and climate, so always check the owner's manual or the oil filler cap for the precise spec.
This article explains what to look for when choosing oil for the 2019 Audi A3, covering petrol and diesel variants, and how to confirm the right viscosity and approvals for your specific model.
Oil specifications by engine type
To help you navigate the choices, here is guidance aligned with the most common 2019 A3 configurations. The exact spec can vary by engine code and market, so verify against your manual or dealer resources.
- Gasoline engines (for example 1.0 TFSI, 1.4 TFSI, 2.0 TFSI): Use a fully synthetic oil that meets VW Group specifications such as VW 504 00 or VW 507 00; typical viscosities are 5W-30, though 0W-30 or 5W-40 may be specified in certain climates or for particular engine codes.
- Diesel engines (for example 2.0 TDI, 1.6 TDI): Use a fully synthetic oil that meets VW 507 00, with a common viscosity of 5W-30; some markets may allow 5W-40, and ensure the oil is compatible with the diesel particulate filter (DPF).
Note: Some specific engine codes or regional versions of the 2019 A3 may require alternative viscosities (such as 0W-20 or 5W-40). Always confirm with the owner's manual or Audi service documentation for your exact version.
Choosing the right oil in practice
Knowing the right oil is about matching both the viscosity and the VW approvals to your engine. Here are practical guidelines to follow when shopping for oil and planning changes.
- Always pick a fully synthetic oil that explicitly carries VW 504 00 and/or VW 507 00 approvals, and note any additional approvals (e.g., ACEA). This ensures compatibility with long-life service intervals and emissions controls.
- Choose the viscosity recommended for your climate and engine code. Five values (5W-30, 0W-30, 5W-40) are the most common in the 2019 A3 range; climate and driving style can influence the correct choice.
- When in doubt, consult the owner’s manual or contact an Audi dealer to confirm the exact specification for your engine code, especially if you have a non-standard climate or driving pattern.
In summary, the typical guidance for a 2019 Audi A3 is a fully synthetic oil meeting VW 504 00/507 00 with a common viscosity of 5W-30. Diesel variants commonly use 5W-30 with 507 00 approval, while some markets or engines may permit 5W-40 or 0W-30 under specific conditions. Always confirm the exact requirement for your vehicle.
Brand options and how to verify approvals
Several reputable brands offer VW-approved oils suitable for the 2019 A3. Look for explicit VW 504 00 and/or VW 507 00 approval on the bottle, along with the appropriate viscosity. Examples include:
- Castrol EDGE 5W-30 LL (Long Life) with VW approvals
- Mobil 1 ESP 5W-30 or 0W-30 with VW approvals
- Shell Helix Ultra 5W-30 with VW approvals
- Total Quartz 9000 5W-30 or 5W-40 with VW approvals
Always verify the exact oil approvals on the product packaging to ensure compatibility with your engine code and climate.
Summary
The 2019 Audi A3 generally requires a fully synthetic oil meeting VW 504 00 or VW 507 00, with 5W-30 being the most common viscosity. Diesel variants typically use 5W-30 with 507 00 approval, while some engines or regions may specify different viscosities. Check your owner’s manual, the oil filler cap, or a dealer for the precise specification tied to your engine code and driving conditions, and choose a reputable brand that clearly lists VW approvals on the bottle.
