In brief, Audi S5 models generally require a fully synthetic motor oil that complies with VW Group specifications. The most common choice is 5W-40, though 5W-30 is used in some engines or climates. The exact spec depends on the model year and engine code, so always check your owner's manual or the oil cap for the correct specification.
Understanding the oil requirements by engine and year
The Audi S5 lineup has evolved from a V8 in earlier generations to a turbocharged V6 in newer models. Because engine design and service intervals vary, the required oil specification can differ by year and engine code. The safe rule is to use a fully synthetic oil that carries a VW Group specification on the bottle—common numbers include 502 00, 504 00, and 507 00—depending on the car.
Common VW/Audi specifications you’ll see
The following specifications cover many S5 engines. Confirm which applies to your car before purchasing.
- VW 502 00 — Broadly compatible with many gasoline engines; often paired with 5W-40 in performance applications.
- VW 504 00 — Long-life standard for newer engines; frequently used with 5W-30.
- VW 507 00 — Long-life, low-SAPS option for extended intervals in certain engines; commonly 5W-30.
When shopping for oil, verify the exact VW Group specification and the viscosity printed on the bottle or in your manual. The wrong combination can affect performance and warranty coverage.
Viscosity guidance and climate considerations
Viscosity choices reflect climate and service intervals. Here’s the practical guidance you’ll encounter for most S5 models:
- Default for many current S5s: 5W-40 synthetic oil that meets VW 502 00 or 504 00.
- Alternative in certain markets or engines: 5W-30 synthetic oil that meets VW 504 00 or 507 00.
In practice, 5W-40 is a reliable default for temperate to hot climates, while 5W-30 can be acceptable in milder climates or when the manufacturer specifies it for extended intervals. Never mix viscosities and avoid non-synthetic blends unless explicitly approved.
How to verify and change oil correctly
To ensure you’re using the exact oil your S5 requires, follow this quick checklist:
- Identify your exact model year and engine code (for example, the 3.0L TFSI in the newer generation) to confirm the required specification.
- Consult the owner's manual or the engine oil specification label on the oil cap to confirm the correct viscosity and VW spec (502 00 / 504 00 / 507 00).
- Choose a reputable fully synthetic oil with the specified VW Group spec and viscosity; avoid blends or brands not explicitly approved.
- Have the oil and filter changed at the manufacturer-recommended interval, or sooner if your driving is aggressive or in extreme conditions.
Following these steps helps ensure optimal performance and proper warranty compliance.
Bottom line and maintenance tips
While the exact requirement depends on your engine and year, the practical rule is to use a fully synthetic oil that meets VW Group specifications (502 00, 504 00, or 507 00) with a viscosity of 5W-40 (or 5W-30 where specified). Regular oil changes and a quality filter are essential for long-term engine health.
Summary: The precise oil for an Audi S5 depends on the year and engine code, but a safe, widely applicable choice is a fully synthetic 5W-40 oil meeting VW Group specs such as 502 00, 504 00, or 507 00. Always verify the exact requirement in your owner’s manual or with a dealer to ensure proper protection and warranty coverage.
