The essential guidance is straightforward: use a full-synthetic engine oil that meets VW 502.00 specification, with 5W-40 being the most common viscosity for the 3.0-liter turbocharged V6 in the 2018 S5. Depending on climate, alternate viscosities such as 0W-40 or 5W-30 may be acceptable if they still meet the 502.00 standard. Always confirm with the owner’s manual or a dealer.
Oil specifications for the 2018 S5
The 2018 Audi S5 uses a 3.0-liter TFSI gasoline engine. Audi requires a fully synthetic motor oil that meets VW 502.00 for gasoline engines. The typical viscosity recommended for everyday use is 5W-40, which offers a balance of cold-start performance and high-temperature protection. In very cold climates, some 0W-40 oils that carry the 502.00 approval may be suitable, while in hotter climates a 5W-40 is generally preferred to maintain film strength and protection. Always verify the exact grade in the owner’s manual and with your local Audi dealer.
Note: The key is to select oil that explicitly carries VW 502.00 approval (or VW 502 00) and is fully synthetic. Using oil that does not meet this spec can affect engine protection, performance, and warranty coverage.
Viscosity guidance
Viscosity describes how thick the oil is at operating temperatures and influences startup friction, protection, and fuel economy. For the 2018 S5, the most commonly used viscosity is 5W-40. Some markets permit 0W-40 or 5W-30 if they also carry VW 502.00 approval and are appropriate for the climate. Always confirm the recommended viscosity in the owner’s manual and ensure the product label shows VW 502.00.
What to look for on a bottle or can: the oil should be labeled fully synthetic and clearly indicate VW 502.00 (or VW 502 00) approval, and the viscosity grade (for example, 5W-40).
- Full synthetic formulation (not mineral or semi-synthetic).
- Meets VW 502.00 specification for gasoline engines.
- Commonly 5W-40; 0W-40 or 5W-30 may be acceptable if they carry the 502.00 approval and suit climate needs.
- Approved by Audi or VW for use in the 3.0L TFSI engine.
In practice, most 2018 S5 owners opt for a high-quality 5W-40 synthetic oil that carries VW 502.00 approval. If you plan to use a different viscosity for climate reasons, double-check that it remains within VW 502.00 guidelines and suits the long-term reliability needs of the engine.
Choosing a brand and product
Choosing a reputable brand that offers VW 502.00-approved oils helps ensure compatibility and warranty compliance. Look for oils that explicitly list VW 502.00 (or 502 00) on the bottle and in the product data sheet. Below are examples of brands and product lines commonly available in many markets that offer VW 502.00-approved 5W-40 synthetic oils. This list is illustrative; always verify the exact specification on the product label.
- Castrol EDGE 5W-40 (A3/B4) with VW 502.00 approval
- Mobil 1 ESP Formula 5W-40 with VW 502.00 approval
- Motul 8100 X-clean 5W-40 with VW 502.00 approval
- Liqui Moly Synthoil High Tech 5W-40 with VW 502.00 approval
Tip: Some regions offer 0W-40 or 5W-30 options that still carry VW 502.00 approval. If you live in an area with extreme cold or heat, consult your dealer about the best viscosity for year-round protection and align with maintenance schedules.
Maintenance notes and oil level checking
Modern Audis, including the 2018 S5, often use electronic oil level monitoring rather than a traditional dipstick. Use the vehicle’s MMI or instrument cluster readouts to check oil level and trend, and follow the service interval recommended by Audi based on driving conditions and the onboard oil life monitor.
Oil change intervals and tips
Oil change intervals vary by driving style, climate, and service plan. The onboard system helps indicate when an oil change is due, and your local dealer or service guide can provide the recommended interval for your vehicle’s configuration. Always use a filter and oil that meet the VW 502.00 specification and avoid mixing brands that do not meet the standard.
Summary
For the 2018 Audi S5, use a full-synthetic oil that meets VW 502.00 specification. The most common viscosity is 5W-40, though certain climates may permit 0W-40 or 5W-30 if they carry the same approval. Always check the owner’s manual and confirm the exact grade with a dealer. Choose a reputable brand whose product label clearly indicates VW 502.00 (or 502 00) approval, and adhere to Audi’s maintenance intervals and electronic oil level checks to protect the engine and preserve warranty.
