What Kind of Oil a 2013 Audi S5 Takes

The 2013 Audi S5 requires full synthetic engine oil that meets Audi/VW specification VW 502 00, typically in SAE 5W-40 or 5W-30 viscosity, with 5W-40 generally being the most commonly recommended weight for the 3.0L supercharged V6 (and also suitable for the earlier 4.2L V8 where VW 502 00 is specified). In practice, owners should choose a high‑quality synthetic oil clearly labeled as meeting VW 502 00 and follow Audi’s maintenance schedule.

Understanding the 2013 Audi S5’s Engine and Oil Requirements

The 2013 Audi S5 sits at an intersection of two engine eras. Early S5 models used a naturally aspirated 4.2‑liter V8, while by 2013, most S5 coupes and convertibles came with a 3.0‑liter supercharged V6 (engine code often referred to as 3.0 TFSI). Both engines are performance-oriented and tightly engineered, which is why Audi ties oil choice to a specific set of standards rather than just a viscosity number.

The Official Specification: VW 502 00

Audi (under the Volkswagen Group umbrella) does not simply ask for “synthetic 5W-40.” Instead, it defines a performance standard known as VW 502 00, which covers aspects like high-temperature stability, deposit control, wear protection, and compatibility with extended drain intervals. For a 2013 S5, that VW 502 00 label is the key requirement.

Why VW 502 00 Matters

VW 502 00 is the standard specified for high-performance gasoline engines without extended flexible service intervals typical of Europe’s LongLife programs. The 3.0 TFSI and 4.2 V8 both operate under higher thermal and mechanical stress than typical commuter engines; oil that merely “seems similar” but is not certified may shear down more quickly, form deposits, or underperform in extreme conditions.

Recommended Viscosity Grades

While the VW 502 00 standard is non-negotiable, viscosity is also important. The owner’s manual for most 2013 S5 models typically recommends 5W‑40 as the default grade for most climates, with 5W‑30 (still VW 502 00 approved) acceptable in some conditions.

Common Approved Viscosity Options

The following list outlines the most commonly recommended viscosity grades that meet Audi’s standards for a 2013 S5, assuming they carry the VW 502 00 approval on the label.

• SAE 5W‑40 full synthetic: Usually the primary recommendation for the 3.0 TFSI and 4.2 V8, offering strong high-temperature protection while still flowing well in cold starts.
• SAE 5W‑30 full synthetic (VW 502 00 approved only): Acceptable alternative, especially in moderate climates, provided the oil explicitly lists VW 502 00 certification.
• Other climate-specific variants: In very cold regions, some manuals allow other viscosity grades if they meet VW 502 00, but 5W‑40 and 5W‑30 remain the norm in North America and Europe.

In practice, most Audi technicians and specialists default to a VW 502 00‑approved 5W‑40 for the 2013 S5, balancing cold-start performance with high‑temperature durability.

Examples of Oils That Meet VW 502 00

Drivers often face a shelf full of synthetic oils, many of which list multiple manufacturer approvals. The crucial step is to check the rear label or product data sheet to see “VW 502 00” explicitly listed among the approvals.

Common Brands and Product Lines

The following examples are widely available oils that, in many current formulations, offer variants carrying VW 502 00 approval. Always confirm the label or current product data sheet, as formulations and approvals can change.

• Castrol EDGE 5W‑40 (often labeled “A3/B4” or “European Formula”): Frequently sold at Audi dealers in some markets and commonly approved for VW 502 00.
• Mobil 1 FS 0W‑40 or 5W‑40 (European Car Formula / ESP variants): Certain versions list VW 502 00; check the bottles or manufacturer site for the exact product code.
• Liqui Moly Top Tec 4200 / 4100 (5W‑30 or 5W‑40 variants): Several Liqui Moly products carry VW 502 00 approval and are popular in European performance cars.
• Motul 8100 series (e.g., X-cess 5W‑40): Some Motul 8100 oils are specifically certified to VW 502 00.
• OEM-branded Audi/VW Genuine oil: Sold through dealerships, often in 5W‑40 or 5W‑30 and labeled explicitly with VW 502 00.

These examples illustrate the type of oils that meet the spec, but the definitive check is the VW 502 00 approval listed on the packaging or the official technical data sheet from the manufacturer.

Capacity and Service Intervals

Beyond type of oil, owners need to know how much oil to use and how frequently to change it. While Audi’s official intervals can be relatively long, many enthusiasts opt for more frequent service due to the S5’s performance nature and potential for spirited driving.

Oil Capacity and Change Frequency

The following list summarizes typical capacity and service practices for a 2013 Audi S5. Values can vary slightly by engine variant and region, so the owner’s manual should be consulted for precise figures.

• Engine oil capacity: Approximately 6.5 to 7.0 liters (about 6.9–7.4 US quarts) including filter for the 3.0 TFSI; the 4.2 V8 is similar but should be confirmed in the manual or service data.
• Factory/service schedule: Often up to about 10,000 miles (15,000 km) or 1 year between oil changes under normal conditions, using VW 502 00 oil.
• Enthusiast practice: Many owners change oil closer to every 5,000–7,500 miles (8,000–12,000 km), particularly if the car sees hard driving, frequent short trips, or hot climates.
• Filter replacement: The oil filter should be replaced at every oil change using an OEM or OEM‑quality filter designed for the 3.0 TFSI or 4.2 V8, as applicable.

While Audi’s official intervals are designed to be convenient, more frequent oil changes with the correct VW 502 00 fully synthetic oil can help maintain engine cleanliness and longevity, especially in a high-performance car like the S5.

How to Verify the Correct Oil for Your Specific S5

Because 2013 was a transitional period and different markets sometimes received different configurations, it is wise to confirm that your individual vehicle matches the general guidance. Audi provides several ways to do this through documentation and labeling on the car itself.

Steps to Confirm Compatibility

The following steps outline how an owner can double‑check the appropriate oil specification for their exact vehicle and conditions.

1. Consult the owner’s manual: The lubrication section will specify “VW 502 00” (or a superseding spec) and list acceptable viscosity grades based on ambient temperatures.
2. Check the under-hood or oil cap labeling: Some vehicles have a sticker or text on the oil cap reminding owners to use oil that meets VW 502 00.
3. Use the VIN at a dealer: An Audi dealer can pull the exact engine code and confirm the recommended oil specification and capacity for your VIN.
4. Check the product data sheet: When considering a specific brand, look up the technical data sheet and verify “VW 502 00” appears under approvals.
5. Ask an Audi-specialist shop: Independent German‑car specialists often have deep familiarity with S5 engines and typical regional recommendations.

Following these steps ensures that the oil you select is not merely similar on paper, but officially approved and matched to the precise requirements of your 2013 S5’s engine.

Risks of Using the Wrong Oil

Using an oil that does not meet the VW 502 00 standard, or one with an unsuitable viscosity for your climate and driving style, can have consequences that might not be immediately obvious but can accumulate over time.

Potential Long-Term Issues

The following points highlight what can happen when non-approved or inappropriate oil is used in a 2013 Audi S5.

• Increased engine wear: Inadequate high-temperature stability or film strength can lead to accelerated wear on camshafts, bearings, and other critical components.
• Sludge and deposits: Oils not formulated to VW 502 00 standards may form deposits on piston rings, turbo/supercharger components, and valvetrain areas, eventually affecting performance.
• Higher oil consumption: Poor shear stability or volatility can increase burn‑off, requiring frequent top‑offs and potentially masking underlying problems.
• Warranty or goodwill complications: For vehicles still under extended coverage or goodwill programs, non-approved oil can complicate claims if engine issues arise.
• Reduced performance: Degraded oil can affect the efficiency of variable valve timing systems and supercharged engine components, subtly reducing responsiveness.

While a single fill of non-approved oil may not instantly damage the engine, repeated use over long intervals can undermine the reliability and performance that define the S5’s character.

Practical Takeaways for 2013 Audi S5 Owners

For many owners, the sheer volume of brands and numbers on oil containers can be confusing. Narrowing the decision down to a few core rules simplifies the process without sacrificing protection.

Core Rules to Follow

The following distilled guidelines capture the essentials of choosing engine oil for a 2013 Audi S5.

• Always demand VW 502 00 approval: Treat this as a requirement, not a suggestion.
• Use full synthetic oil: Do not substitute conventional oil or “synthetic blends” that lack VW 502 00 certification.
• Prefer 5W‑40 unless your manual or climate suggests otherwise: This is the default viscosity for most use cases.
• Change oil regularly: Even with long-life synthetic, consider 5,000–7,500‑mile intervals if you drive hard or mostly in city traffic.
• Stick with reputable brands or OEM oil: Choose well-known manufacturers or genuine Audi/VW-branded oil to reduce the risk of mislabeling or changing formulations.

By following these straightforward principles, S5 owners can maintain the performance and durability of their engines without needing to become lubrication experts.

Summary

The 2013 Audi S5 is engineered to run on full synthetic engine oil that meets the Volkswagen Group’s VW 502 00 specification. For most owners and climates, a 5W‑40 synthetic oil with explicit VW 502 00 approval on the label is the most appropriate choice, with some 5W‑30 VW 502 00 oils also acceptable. Typical capacity is roughly 7 quarts including the filter, and while Audi’s official change interval can reach about 10,000 miles or 1 year, many enthusiasts prefer 5,000–7,500‑mile intervals. Verifying the spec in the owner’s manual and on the oil container remains crucial: the letters “VW 502 00” are more important than the brand name alone.
