The 2018 Audi A5 typically uses a fully synthetic motor oil with a viscosity of 5W-30 or 5W-40 that meets Volkswagen's VW 502 00 specification; the exact requirement depends on the engine variant and market, so always verify in the owner's manual or on the oil cap.
Engine options and oil basics
Understanding which engine your A5 has helps determine the precise oil specification. The 2018 lineup commonly includes a 2.0-liter turbocharged TFSI engine and, in higher trims such as the S5, a 3.0-liter TFSI V6. Each engine uses synthetic oil that conforms to VW Group specifications, and regional differences can apply.
Oil specifications by engine
Below are typical guidelines, but always confirm with the official manual or a dealer, as requirements can vary by country and model year.
- 2.0L TFSI (40 TFSI) gasoline engines: commonly require a fully synthetic 5W-30 or 5W-40 oil that meets VW 502 00; some regions also accept VW 504 00 or 507.00 for long-life service.
- 3.0L TFSI V6 (used in the S5): typically uses a fully synthetic 5W-40 oil meeting VW 502 00; in some markets 5W-30 is acceptable depending on service plan.
- 2.0L TDI (diesel, in markets where offered): usually requires synthetic oil meeting VW 507.00 (long-life diesel standard) with viscosity such as 5W-30; availability varies by market.
Consulting the owner’s manual or your dealer will confirm the exact grade and VW specification for your particular car and region.
How to confirm the right oil for your car
To ensure you use the correct oil, follow these verification steps:
- Check the owner's manual for the exact viscosity and VW specification listed for your engine variant.
- Look at the engine oil filler cap, which often indicates viscosity (for example, 5W-30 or 5W-40) and sometimes a specification code.
- If in doubt, ask a dealer or a certified Audi service center to confirm the required oil spec for your VIN.
- Use a current, fully synthetic oil that meets the specified VW standard and viscosity; avoid mineral or off-spec oils.
Using the correct oil helps maintain performance, efficiency, and engine longevity, particularly with turbocharged engines common in the A5 lineup.
Climate considerations and service planning
The climate and driving style can influence the preferred viscosity. Warmer climates or aggressive driving often favor a 5W-40, while milder or colder climates may perform well with 5W-30. The service interval (standard vs. long-life) will also affect oil choice and capacity of the oil system. Always align with Audi's recommended service plan for your market.
In general, use fully synthetic oil that meets VW 502 00 and related specifications; never mix synthetic brands unnecessarily.
Summary
For a 2018 Audi A5, the recommended oil is a fully synthetic motor oil, typically 5W-30 or 5W-40, meeting VW 502 00. Exact requirements depend on engine variant and market, so verify via the owner's manual, the oil cap, or an Audi service advisor. Using the correct spec supports engine performance and longevity across all variants of the A5 lineup.
