What Is the Best Oil to Put in an Audi?

The best oil for most modern Audi vehicles is a fully synthetic engine oil that meets Audi/VW’s own specifications—typically VW 502 00, 504 00, 508 00, or their diesel equivalents—with a common viscosity of 0W‑20, 0W‑30, or 5W‑40 depending on the engine and model year. The exact “best” oil is whatever matches the specification and viscosity printed in your owner’s manual or on the under‑hood label, often from brands like Castrol, Mobil 1, Liqui Moly, or Motul that explicitly state VW/Audi approvals.

How Audi Chooses Its Recommended Oil

Audi does not simply recommend “synthetic 5W‑30” and walk away. Instead, the brand uses its parent company’s standardized approvals—Volkswagen Group (VW) oil specs—that define performance, additives, and compatibility with specific engines and service intervals. These specifications are more important than brand or generic viscosity alone.

Key VW/Audi Oil Specifications for Gasoline Engines

For gasoline engines in North America and Europe, Audi typically relies on a small group of VW specs tailored to engine design, emissions systems, and service intervals. Understanding these codes helps you choose an oil that actually matches what the engine was designed for.

The following list outlines the most common VW/Audi oil specifications for gasoline engines and where they’re typically used.

• VW 502 00 – High‑performance synthetic oil for many older and some mid‑2010s gasoline engines, especially 2.0 TFSI and 3.2/3.0 V6 engines without ultra‑long “flexible” service intervals. Often paired with viscosities like 5W‑30 or 5W‑40.
• VW 504 00 – Low‑ash, long‑life oil for many newer direct‑injection gasoline engines with strict emissions controls and long service intervals. Common viscosities: 0W‑30 or 5W‑30.
• VW 508 00 – Newest “ultra‑low viscosity” spec for modern engines geared toward efficiency and low CO₂, often requiring 0W‑20 and used in many recent Audi models (e.g., late‑2010s and 2020s turbo 4‑cylinders and some mild hybrids).
• VW 503 00 / 503 01 (legacy) – Earlier long‑life specs mostly superseded by 504 00 but still referenced on some older documentation; if your manual lists these, most dealers will now use a compatible 502 00 / 504 00 product.

These specs govern detergent packages, high‑temperature performance, and compatibility with catalytic converters and particulate filters, making them the backbone of Audi’s oil recommendations.

Key VW/Audi Oil Specifications for Diesel Engines

For TDI models and other diesel engines, Audi uses slightly different specifications that account for diesel soot, higher combustion pressures, and after‑treatment systems like diesel particulate filters (DPF).

The list below summarizes the main diesel‑oriented VW/Audi oil specifications and their typical applications.

• VW 505 01 – Older diesel spec geared to pump‑duse (PD) TDI engines; still relevant for certain legacy European‑market diesels but largely historical in North America.
• VW 507 00 – Low‑SAPS (low ash, phosphorus, sulfur) long‑life oil for modern TDI engines with DPF, including many Audi TDI cars and SUVs from the late 2000s onward. Usually 5W‑30.
• VW 506 01 / 506 00 (legacy long‑life) – Older long‑drain specifications now largely superseded by 507 00; if your diesel is newer, 507 00 is typically the required or preferred spec.

Selecting the correct diesel oil spec is critical to protect high‑pressure fuel systems and DPFs, preventing premature clogging or component wear.

Viscosity: 0W‑20 vs 5W‑40 vs 5W‑30

After confirming the correct VW specification, viscosity—how thick or thin the oil is at different temperatures—is the next key factor. Audi picks viscosity based on engine design, tolerances, turbocharging, and target fuel economy.

Common Audi Engine Oil Viscosities

Different Audi models and generations call for different viscosities, and this can change with technical updates and regional climate guidelines. The list below shows the most common viscosities you’ll encounter and how they’re typically used.

• 0W‑20 – Increasingly common in new Audi gasoline engines meeting VW 508 00. Designed for low friction and high fuel economy, especially in mild hybrid systems and efficient turbo engines built from the late 2010s onward.
• 0W‑30 – Used in some VW 504 00 applications, offering excellent cold‑start performance in colder climates while still providing protection at operating temperature.
• 5W‑30 – A long‑standing default in many Audi applications, compatible with VW 502 00, 504 00, or 507 00 specifications depending on the exact product. Often used in both gasoline and diesel engines.
• 5W‑40 – Common in performance‑oriented or older turbocharged engines requiring VW 502 00, such as earlier S4, A4 2.0T, and some V6/V8 engines; favored where higher high‑temperature protection is desired.

While you may see several viscosities marketed as “for Audi,” you should match the one printed in your owner’s manual or service booklet, adjusting only if Audi or a trusted specialist recommends a region‑ or climate‑specific alternative.

Brand vs. Specification: Does It Matter?

Oil brands compete heavily for Audi drivers, but from the engineering standpoint, the VW specification and viscosity matter more than the logo on the bottle. That said, some brands maintain close partnerships with Audi or are widely recognized on dealer shelves.

Major Oil Brands Commonly Used in Audi Vehicles

While any oil that genuinely meets the VW spec and viscosity is acceptable, certain brands are more commonly recommended by dealers, independent specialists, and Audi owner communities.

• Castrol Edge / Castrol Edge Professional – Historically factory‑fill and official partner oil in many markets; offers VW 502 00, 504 00, 507 00, and 508 00 approved variants in 0W‑20, 5W‑30, and 5W‑40.
• Mobil 1 – Widely available with multiple VW‑approved formulations (e.g., Mobil 1 ESP meeting 504 00/507 00, and other lines for 502 00). A common upgrade choice in North America and Europe.
• Liqui Moly – Popular among enthusiasts and independent German‑car specialists; clearly labels VW approvals and offers formulations tailored to TFSI and TDI engines.
• Motul – Known for performance‑oriented oils and specific VW‑approved products for turbocharged and high‑output engines.
• Shell Helix / Pennzoil (regional brands) – Depending on market, these brands provide VW‑approved oils used by some dealers and quick‑service centers.

Within each brand, not all products meet VW/Audi approvals, so always verify the exact VW spec (e.g., “VW 504 00/507 00 approved”) on the label rather than relying only on the brand name or generic “European formula” marketing.

How to Find the Best Oil for Your Specific Audi

Because Audi’s lineup spans everything from compact A3s to RS performance models and large SUVs, there is no single oil that fits every car perfectly. The “best” oil is the one that exactly matches your car’s requirements and driving conditions.

Step‑By‑Step: Determining the Correct Oil

The following steps outline a practical way for any Audi owner to identify the safest and most suitable engine oil, whether buying it themselves or verifying a service shop’s choice.

1. Check the owner’s manual or service booklet – Locate the section on engine oil; note the required VW specification (e.g., 502 00, 504 00, 508 00) and viscosity (e.g., 0W‑20, 5W‑40).
2. Look under the hood or on the oil cap – Many newer Audi models display the required spec directly in the engine bay or on the filler cap, which can confirm or update what’s in the manual.
3. Check for technical service bulletins (TSBs) – For some engines, Audi has updated recommended oil specs over time (for example, after addressing issues like consumption or timing chain wear); dealers can check this by VIN.
4. Match the label on the oil bottle – Ensure the bottle states “VW 504 00/507 00” or whatever your car requires, and that the viscosity matches or is within the approved range.
5. Consider your climate and driving style – In very cold regions, a 0W‑rated oil from the approved list can improve cold starts; for frequent high‑load or track use (especially in older performance models), a 5W‑40 within spec is often preferred.
6. Avoid mixing non‑approved oils – While topping up in an emergency is acceptable, routine mixing of different specs or using generic oils can compromise long‑term protection and warranty.

Following these steps keeps your decision grounded in Audi’s engineering requirements rather than marketing claims or hearsay from non‑specialist service centers.

Oil Change Intervals and Why They Matter

Using the correct oil is only half of the equation; changing it at appropriate intervals is just as crucial. Audi’s long service intervals—sometimes up to 10,000–12,000 miles (15,000–19,000 km) or once a year—are based on using the exact specified oil under normal conditions.

Recommended Oil Change Practices for Audi Owners

Owners often wonder whether to strictly follow Audi’s flexible intervals or change oil more frequently for additional peace of mind. These common practices strike a balance between manufacturer guidance and real‑world experience.

• Follow the car’s service indicator for normal driving – If you drive mostly highway miles in moderate climates and use the correct VW‑approved oil, the dashboard indicator is generally a safe guide.
• Shorten intervals for severe use – If you do many short trips, cold starts, city stop‑and‑go driving, or tow regularly, consider oil changes around 5,000–7,500 miles (8,000–12,000 km), even if the car allows more.
• Be conservative with turbo and performance engines – S and RS models, as well as heavily turbocharged engines, benefit from more frequent oil changes due to higher thermal loads.
• Respect time limits – Even with low mileage, oil should be changed at least once every 12 months, as moisture and fuel dilution accumulate over time.
• Monitor consumption – Some Audi engines, especially certain older 2.0 TFSI units, are known to consume oil; check the dipstick or MMI level display regularly and top up with the same spec when needed.

Appropriate intervals, combined with a correct VW‑approved synthetic oil, significantly reduce risks of sludge, timing component wear, and turbocharger issues over the life of the vehicle.

What About Older, High‑Mileage, or Modified Audis?

Not all Audis live their lives in factory‑standard condition. Owners of older, high‑mileage, or tuned vehicles often ask whether thicker oils, additives, or non‑standard products are beneficial or harmful.

Special Considerations Beyond Factory‑Stock Cars

When dealing with non‑standard or aging engines, a few targeted adjustments can help, but they must still respect the underlying VW specifications wherever possible.

• High‑mileage engines – Some mechanics recommend a slightly higher‑viscosity approved oil (e.g., 5W‑40 instead of 5W‑30) in older, worn engines to help reduce consumption and maintain oil pressure, as long as it still carries the correct VW spec.
• Heavily tuned or track‑driven cars – Performance‑oriented fully synthetic oils that meet or exceed the factory VW spec, often in 5W‑40 or 0W‑40, can provide a broader safety margin at high temperatures.
• Oil additives – Many Audi specialists caution against generic aftermarket oil additives, as they can disrupt the carefully balanced additive packages in VW‑approved oils and interfere with emissions systems.
• Engine cleaning flushes – In cases of severe sludge, professional flushes may be used, but routine use of harsh flush chemicals is typically discouraged; frequent oil changes with the correct oil are usually safer.

Even in these edge cases, starting from Audi’s original specification and working with a knowledgeable specialist is usually better than experimenting with unapproved products.

Summary: Choosing the Best Oil for Your Audi

For an Audi, the best engine oil is a fully synthetic product that explicitly meets the VW specification and viscosity required for your specific model and engine—commonly VW 502 00, 504 00, 507 00, or 508 00—sourced from a reputable brand such as Castrol, Mobil 1, Liqui Moly, or Motul. Matching the spec and viscosity listed in your owner’s manual or under the hood is more important than the brand itself.

Gasoline engines typically use specs like 502 00, 504 00, or the newer 508 00, with viscosities ranging from 0W‑20 to 5W‑40. Diesel TDIs generally require low‑ash 507 00 oils, usually in 5W‑30 weight. Owners should confirm the exact requirement by checking the manual, the oil cap, or dealer documentation, then buy a VW‑approved oil that fits these criteria.

Regular oil changes—aligned with Audi’s service intervals and adjusted for severe driving conditions—help keep timing systems, turbos, and emissions components healthy. For older, high‑mileage, or tuned cars, modest adjustments in viscosity are sometimes justified, but only within the framework of VW‑approved oils.

If in doubt, consult your Audi dealer or a trusted independent specialist with your VIN. With the correct VW specification, proper viscosity, and sensible change intervals, you’ll give your Audi the protection it was engineered to have and maximize its reliability and longevity.

Which oil does Audi recommend?

Audi engines require full-synthetic oil, with common types being 5W-30, 0W-40, and 5W-40, though the specific type depends on the model and climate. The correct oil must meet specific Audi/VW specifications, such as VW 502 00, VW 504 00, or LL-01, which can be found in the owner’s manual. Always consult your owner’s manual for the exact specification recommended for your vehicle. 
Common Audi oil types

• 5W-30: A common choice that balances fuel efficiency and wear protection, suitable for many engines in moderate climates.
• 0W-40: Excellent for cold climates because it provides better cold-start protection.
• 5W-40: Often recommended for higher-performance models and turbocharged engines, as it offers good protection in warmer climates. 

Why full-synthetic oil is crucial

• Audi engines are designed for the superior performance of synthetic oil. 
• Conventional oil can break down too quickly, leading to poor lubrication, sludge buildup, and potential damage to the engine and turbocharger. 

How to find the right oil

• Check your owner’s manual: This is the most important step, as it lists the exact viscosity and specification required for your engine. 
• Look for Audi/VW specifications: Ensure the oil you choose meets the specific Audi or Volkswagen approval number, such as VW 502 00, VW 505.00, or LL-04. 
• Consider your climate: Choose a viscosity grade that is appropriate for your local temperature conditions. 

How often does Audi need an oil change?

The recommended Audi oil change interval is typically every 10,000 miles or one year, whichever comes first. However, many sources advise changing the oil more frequently, around 5,000 to 7,500 miles, especially for short trips or heavy city driving, to help extend engine life and prevent sludge buildup. Always consult your specific owner’s manual and use high-quality, manufacturer-approved synthetic oil.

Oil change interval recommendations 

• Standard recommendation: 10,000 miles or one year. 
• For frequent short trips or heavy city driving: 5,000 to 7,500 miles. 
• For long-distance highway driving: The 10,000-mile interval is often sufficient, but 7,500 miles is still a good preventative measure. 

Factors that may shorten the interval

• Short-distance city driving: This leads to the engine not reaching optimal operating temperature, which can contaminate the oil faster. 
• Stop-and-go traffic: This also causes more stress on the engine and oil. 
• Dusty or hot conditions: These environmental factors can also degrade oil more quickly. 
• High-performance use: Modifying your car or driving it aggressively can benefit from more frequent oil changes. 

Signs you need an oil change sooner 

• Your “check engine” or oil light comes on.
• The oil on the dipstick appears dark, thick, or gritty.
• You hear engine knocking sounds.
• You notice low oil levels. 

Best practices

• Always use the correct high-quality synthetic oil specified in your owner’s manual. 
• Change the oil filter with every oil change. 
• Reset your car’s “service due” indicator after the oil change.
