For most Audi S4 models, the standard answer is a fully synthetic oil that meets VW/Audi spec VW 502 00, with 5W-40 being the most common viscosity. Always verify the exact requirement in your owner's manual or on the oil cap, as there can be year-to-year variations.
Oil recommendations by engine and climate
The Audi S4 has spanned several generations and engine configurations. While 5W-40 synthetic oil meeting VW 502 00 is the prevailing baseline for many modern S4s, some years and markets allow alternatives (such as 0W-40 or 5W-30) provided they carry the same VW approval. The key is to match the specification and viscosity your specific car requires.
- Standard recommendation: 5W-40 full synthetic oil that meets VW 502 00 approval is commonly used across recent S4 models with 3.0 TFSI engines.
- Alternative in certain climates or service schedules: 0W-40 or 5W-30 synthetic oil can be acceptable if it also carries the VW 502 00 approval and your manual permits it.
- Older or non-3.0 configurations: oil specifications can differ; always consult the exact guidance for your model year and engine code.
In short, the most reliable starting point is a fully synthetic 5W-40 oil that carries VW 502 00 approval, but always confirm with your manual or dealer for your specific S4 variant.
How to verify the exact specification for your car
To be certain you’re using the right oil, check these sources before buying:
- Owner’s manual or the maintenance booklet for the exact viscosity and VW/Audi approval required.
- Oil filler cap under the hood, which often lists the required specification.
- VIN-based service portal or a dealership service advisor for your exact model and year.
Verifying through these channels helps ensure you meet the manufacturer’s standards and preserve warranty coverage.
Oil change intervals and practical considerations
Oil type is only part of the equation. Interval length depends on driving conditions, model year, and whether your S4 is on a standard or long-life service plan.
- Typical drain intervals: many owners follow roughly 5,000–7,500 miles (8,000–12,000 km) between changes under standard service schedules.
- Long-life intervals: some newer Audi vehicles use extended intervals (often up to 10,000–15,000 miles or more) if the oil and vehicle meet the long-life specifications and live in appropriate duty cycles.
- Branding and compatibility: choose fully synthetic oils from reputable brands (for example Castrol, Mobil 1, Pennzoil) that explicitly list VW 502 00 (or the exact approved VW/Audi spec) on the bottle.
Always align the interval with the guidance in your manual and your driving conditions. If you tow, drive aggressively, or frequently do short trips, you may need more frequent changes.
Summary
For most Audi S4s, use a fully synthetic oil that meets VW 502 00, with 5W-40 being the typical viscosity. Confirm the exact specification and interval for your year and engine code via the owner's manual, oil cap, or a dealer. When in doubt, opt for a well-known brand oil that clearly states VW 502 00 approval and follow the recommended service intervals to protect engine performance and longevity.

Is 5W-30 ok for Audi?
Oil Viscosity Recommendations
SAE 5W-30: Ideal for a wide range of temperatures and common for most Audi engines. SAE 5W-40: Provides additional protection in warmer climates or for turbocharged engines. SAE 0W-30: Suitable for cold weather and newer Audi models with advanced engines.
Does it matter if I use 5W30 or 5W40?
5W30 is thinner at operating temperature, offering better fuel efficiency, while 5W40 is thicker, providing enhanced engine protection under high loads, long-distance driving, or hot climates. Both have the same cold-start rating (5W) for smooth lubrication in low temperatures.
