What Kind of Oil a 2019 Audi A4 Takes

A 2019 Audi A4 generally requires fully synthetic engine oil that meets Audi/VW specification VW 502 00 (for most gasoline engines) or VW 504 00 (for some newer long-life intervals), typically in SAE 0W‑40, 5W‑40, or 0W‑30 viscosity depending on climate and engine variant. In practical terms, most U.S. owners of a 2019 A4 2.0T will use a high‑quality, full‑synthetic 0W‑40 or 5W‑40 oil labeled as meeting VW 502 00. The exact spec and viscosity are listed in the owner’s manual and on the under‑hood oil label.

Why Oil Specification Matters for the 2019 Audi A4

The 2019 Audi A4 is built around a turbocharged, high‑efficiency engine that operates under higher temperatures and pressures than many older powertrains. Because of this, Audi specifies not only a particular viscosity grade, but also a strict manufacturer oil standard—VW 502 00 or VW 504 00 for gasoline engines, and VW 507 00 for diesel engines—to protect the turbocharger, ensure proper lubrication, and maintain emissions systems. Using oil that meets these standards is essential for performance, engine longevity, and in some regions, warranty compliance.

The Official Oil Specifications for the 2019 Audi A4

Audi’s requirements are based on Volkswagen Group (VW) internal oil standards, which are more specific than simply saying “synthetic 5W‑40.” These standards define how the oil must perform in terms of resistance to breakdown, sludge formation, wear, and compatibility with turbochargers and emissions systems.

Common Audi/VW Oil Specifications for the A4

The following list explains the main VW oil specifications you are likely to encounter for a 2019 Audi A4 and what they mean for everyday owners.

• VW 502 00: The most common specification for modern gasoline Audi engines in North America, including many 2.0 TFSI engines in the 2019 A4. It is designed for high‑performance engines and is typically paired with normal drain intervals (often ~10,000 miles or 1 year, depending on region and service schedule).
• VW 504 00: A newer “long‑life” specification used in some markets, often with flexible service intervals and low‑SAPS (low‑ash) formulations. Some 2019 A4s in Europe or other regions may call for VW 504 00 instead of 502 00.
• VW 507 00: Primarily a diesel‑engine spec, low‑ash oil for DPF (diesel particulate filter) compatibility. It applies to diesel versions of the A4 that were sold in select markets, not typical U.S. gasoline models.
• VW 508 00/509 00: Ultra‑low‑viscosity oils (e.g., 0W‑20) for the newest generation of engines. These are generally not specified for the 2019 A4 2.0T in most markets, but may appear in some late‑model or regional variants—always check the owner’s manual.

Understanding these codes helps you avoid relying solely on viscosity and instead select an oil that matches Audi’s engineered performance and protection targets for the 2019 A4.

Recommended Viscosity Grades for the 2019 Audi A4

Viscosity—numbers like 0W‑40 or 5W‑40—describes how thick or thin oil is at different temperatures. Audi typically approves a range of viscosities for a given engine, adjusted for climate, while insisting that the oil also meet the appropriate VW specification.

Typical Viscosities for the 2019 A4 2.0T Gasoline Engine

The list below outlines the most commonly recommended viscosity grades for a 2019 Audi A4 gasoline model, particularly the 2.0‑liter turbocharged (2.0 TFSI) engine, in relation to climate conditions.

• 0W‑40 (VW 502 00 or 504 00): A very common choice in moderate to cold climates. It flows easily at low temperatures for cold starts while still providing strong protection at operating temperature.
• 5W‑40 (VW 502 00): Widely used in North America and suitable for a broad temperature range. It is a robust option for mixed driving and warmer regions, provided it meets the correct VW specification.
• 0W‑30 (VW 504 00 or 502 00, depending on product and region): Sometimes specified in markets emphasizing fuel economy and extended service intervals. This grade may be recommended in Europe or regions where VW 504 00 is common.

These viscosities all aim to balance cold‑start protection, high‑temperature stability, and fuel efficiency, with the exact recommended grade depending on the engine variant and ambient climate detailed in the owner’s manual.

Real‑World Examples of Suitable Oils

While Audi does not endorse specific brands in a commercial sense, many well‑known oil manufacturers produce products that explicitly state they meet VW 502 00 or 504 00. Reading the back label is essential: it should clearly say “meets” or “approved to” the relevant VW spec, not just “recommended for use in.”

Common Aftermarket Oils That Typically Meet VW 502 00

The following examples illustrate the types of products that often meet the 2019 Audi A4’s needs; specific availability can vary by country, and owners should always confirm the exact spec on the bottle or the manufacturer’s website.

• Castrol Edge 0W‑40 or 5W‑40 (VW 502 00): Frequently used in European‑spec vehicles and often promoted in dealership settings for German cars.
• Mobil 1 FS 0W‑40 (formerly “European Car Formula”): A popular full‑synthetic oil that typically lists VW 502 00 approval and is widely available in North America and Europe.
• Liqui Moly Top Tec / Special Tec series (0W‑40, 5W‑40 with VW 502 00 or 504 00): German‑made oils commonly used by independent European‑car specialists.
• Shell Helix Ultra / Pennzoil Platinum Euro 5W‑40 or 0W‑40 (VW 502 00): Another series of oils formulated specifically for European specifications, including Audi/VW approvals.
• OEM‑branded Audi/VW oil (often 0W‑30, 0W‑40, or 5W‑40): Sold at dealers, pre‑approved for the correct VW spec, and typically labeled with VW 502 00, 504 00, or 507 00 as required.

These examples show that the key is not the brand name itself but the certification: any oil clearly meeting VW 502 00 (or VW 504 00, where specified) and the recommended viscosity is suitable for a 2019 Audi A4 gasoline engine.

How to Confirm the Correct Oil for Your Exact 2019 A4

Not every 2019 Audi A4 is identical—engine variants, regional regulations, and optional equipment can alter the exact oil requirement. The most authoritative information is always what Audi provides for your specific vehicle.

Where to Look for the Official Requirement

The following steps help ensure you are using the precise oil spec your particular A4 needs, rather than relying solely on general guidance.

1. Check the owner’s manual: The “Engine Oil” section lists approved VW oil standards and recommended viscosity ranges for your engine code and climate.
2. Look under the hood or on the oil cap: Some vehicles have a label or printed note indicating a specific VW spec, such as “Use only VW 502 00 oil.”
3. Verify via VIN at an Audi dealer: A dealership can look up your car’s build information by VIN and confirm the correct oil spec and capacity.
4. Consult Audi’s official technical documentation online (where available): In some regions, Audi provides digital owner’s manuals and technical bulletins accessible by VIN or model year.

Following these steps ensures you match Audi’s precise recommendations, which is especially important if your car has a less common engine variant or was imported from another market.

Oil Change Intervals and Practical Tips

Oil type and oil change interval are closely linked. Audi designed its service schedules around specific oil standards; deviating from those by using lower‑quality oil or stretching intervals beyond recommendations can increase wear, especially on turbocharged engines.

Typical Service Intervals and Best Practices

The points below summarize common guidance for maintaining oil health and engine longevity in a 2019 Audi A4, bearing in mind that exact intervals can vary by market and driving profile.

• Standard intervals: Many 2019 Audi A4s use service intervals of up to 10,000 miles (approximately 15,000 km) or 12 months, whichever comes first, when using approved VW 502 00 or 504 00 oils and following the car’s service indicator.
• Severe driving conditions: Frequent short trips, extreme heat or cold, heavy traffic, or spirited driving may justify more frequent oil changes (for example, every 5,000–7,500 miles / 8,000–12,000 km).
• Always use a quality filter: Pairing the correct oil with an OEM or OEM‑equivalent oil filter ensures proper flow and filtration, especially critical for turbocharged engines.
• Monitor oil level electronically and manually: Many Audi A4s rely on electronic level sensors instead of a traditional dipstick, but checking levels regularly via the car’s menu (and visually, if a dipstick is present) helps catch consumption issues early.
• Stay within the specification if topping up: If you add oil between services, use the same VW‑approved specification and similar viscosity to avoid mixing incompatible formulations.

Adhering to recommended intervals and best practices, combined with the correct VW‑approved synthetic oil, helps the 2019 A4’s engine perform reliably and efficiently over high mileage.

Key Takeaways

To sum up, a 2019 Audi A4 gasoline model is engineered to run on fully synthetic oil that meets Audi/VW standards—most commonly VW 502 00, and in some markets VW 504 00—using viscosities like 0W‑40, 5W‑40, or occasionally 0W‑30. Diesel variants require VW 507 00 low‑ash oils. Owners should always confirm the exact spec in the owner’s manual, on under‑hood labels, or through an Audi dealer using the vehicle’s VIN.
