The 2018 Audi Q7 generally uses a fully synthetic 5W-40 engine oil that meets VW 502.00 specifications. Always check your owner’s manual or the oil filler cap for the exact grade and spec required for your engine variant.
Gasoline engines
The two main gasoline options in many markets were the 3.0L V6 TFSI and the 2.0L TFSI. Both typically require a high-quality fully synthetic oil that meets VW/Audi standards.
- 3.0L V6 TFSI (gasoline) — Fully synthetic 5W-40 oil that meets VW 502.00.
- 2.0L TFSI (gasoline) — Fully synthetic 5W-40 oil that meets VW 502.00.
Whichever gasoline engine you have, ensure the oil conforms to the VW 502.00 specification and follow the service interval recommended by Audi for your vehicle.
Diesel engines
In markets where the Q7 is equipped with a diesel engine, such as the 3.0L TDI, the oil specification is typically different to protect emissions systems.
- 3.0L TDI (diesel) — Fully synthetic 5W-40 oil that meets VW 507.00 (low SAPS).
Diesel variants require the VW 507.00 specification to meet emission standards and protect the diesel particulate filter. Always confirm the correct grade and spec for your vehicle.
Summary
For a 2018 Audi Q7, expect a 5W-40 fully synthetic oil that meets VW 502.00 for gasoline engines, and a 5W-40 that meets VW 507.00 for diesel engines. Double-check your manual or oil cap for the exact requirement, as specifications can vary by market and engine code.
