What Oil Does a 2009 Audi Take?

A 2009 Audi typically requires fully synthetic engine oil that meets specific VW/Audi standards such as VW 502 00 or VW 504 00, with the most common viscosity grades being 5W-40 and 5W-30. The exact oil specification depends on the model and engine (gasoline vs. diesel), so checking the owner’s manual or the label in the engine bay is essential for accuracy.

Why Oil Specification Matters for a 2009 Audi

For a 2009 Audi, using any generic synthetic oil is not enough; the oil must meet VW/Audi’s own specifications to protect the engine, maintain performance, and avoid long-term damage. These specifications govern how the oil behaves at high temperatures, how it protects under stress, and how it interacts with emissions-control systems, which became more sophisticated in vehicles from this era.

Key Oil Specifications for 2009 Audi Models

Most 2009 Audi models share a common set of official oil specifications, even though the engines and performance levels differ across the range. These specifications are printed in the owner’s manual and often on a sticker under the hood or inside the fuel filler door.

Core VW/Audi Oil Standards

The following list outlines the primary Volkswagen Group (VW/Audi) oil standards relevant to 2009 Audi vehicles and what they are generally used for.

• VW 502 00: The most common specification for 2009 Audi gasoline engines (non-diesel). Used for conventional fixed-interval oil changes on many turbocharged and naturally aspirated petrol engines.
• VW 504 00: A higher-spec “LongLife” oil for extended service intervals on many modern gasoline engines, especially in regions where flexible service intervals are enabled.
• VW 505 00: Older diesel specification, sometimes listed for earlier TDI engines; may appear as a backward-compatible option depending on region and engine code.
• VW 507 00: Low-ash “LongLife” oil for modern clean-diesel TDI engines with diesel particulate filters (DPF). Widely used on 2009 Audi diesel models in Europe and markets where TDI engines are sold.

Together, these specifications define what oils are safe and appropriate for the 2009 Audi lineup, and any oil you buy should clearly display the relevant VW standard on the container label.

Common Viscosity Grades for 2009 Audi Engines

A 2009 Audi usually runs on multi-grade fully synthetic oil, with viscosity chosen to balance cold-start protection and high-temperature stability. While VW/Audi’s spec number is mandatory, viscosity can vary slightly based on climate and driving style.

Typical Viscosity Recommendations

The following list summarizes the most commonly recommended viscosity grades for 2009 Audi engines under normal conditions.

• 5W-40 (Full Synthetic): Very common for VW 502 00–approved oils, especially in North America and moderate-to-warm climates; offers strong protection for turbocharged engines.
• 5W-30 (Full Synthetic): Frequently used with VW 504 00 and VW 507 00 oils, particularly for “LongLife” or extended service intervals and for modern gasoline and diesel engines with emissions systems.
• 0W-30 or 0W-40: Sometimes recommended in colder climates for improved cold-start performance, as long as the oil also meets the correct VW specification.

While viscosity influences how the oil flows at different temperatures, it must always be paired with the appropriate VW standard to be fully compatible with a 2009 Audi engine.

Model-by-Model Overview: Typical 2009 Audi Oil Requirements

Different 2009 Audi models and engines may use different specifications based on fuel type (gasoline vs. diesel), turbocharging, and regional emission rules. The following breakdown covers the most common platforms and engines found in the 2009 model year.

2009 Audi A3

The 2009 Audi A3 was offered in various configurations around the world, including turbocharged gasoline engines and TDI diesels. Each engine type has a preferred oil spec but often shares viscosity options.

Below is a general guide to typical oil requirements for the 2009 Audi A3 lineup (exact engine codes and regional variants may differ).

• Gasoline (e.g., 2.0 TFSI, 1.8 TFSI): Usually VW 502 00 (or VW 504 00 where LongLife servicing is enabled), commonly in 5W-40 or 5W-30 full synthetic.
• Diesel TDI (with DPF): Typically VW 507 00 low-ash 5W-30 oil, designed to protect the diesel particulate filter and support extended service intervals.

While this overview applies to many markets, owners should verify their specific engine code and market documentation, as European and North American A3 models sometimes differ in detail.

2009 Audi A4 (B8 Generation)

The 2009 Audi A4 (B8) is one of the most common 2009 Audis on the road, with popular turbocharged four-cylinder and six-cylinder engines. Oil requirements here are especially important due to turbocharging and tight tolerances.

The following list outlines typical oil recommendations for major A4 engines from this model year.

• 2.0 TFSI (Gasoline Turbo): Usually requires VW 502 00 (or VW 504 00 in LongLife markets), with 5W-40 or 5W-30 full synthetic commonly used. High-quality oil is crucial due to turbo heat and potential carbon buildup.
• 3.2 FSI V6 (Gasoline): Typically VW 502 00-approved synthetic oil, often in 5W-40, though 5W-30 may be listed as an option in some regions.
• 2.0 TDI / 2.7 TDI / 3.0 TDI (Diesel, where available): Generally VW 507 00 low-SAPS 5W-30, chosen for compatibility with DPF and high-pressure injection systems.

Because the A4 commonly uses flexible or extended service intervals in some markets, following the correct VW spec (502/504/507) is vital for avoiding sludge, timing-chain issues, and turbo wear.

2009 Audi A5

The 2009 Audi A5 shares much of its mechanical DNA with the A4, including engines and oil requirements, especially in 2.0 TFSI and 3.2 FSI configurations.

The list below summarizes typical oil needs for these models.

• 2.0 TFSI (Gasoline): Commonly VW 502 00 or VW 504 00, with 5W-40 or 5W-30 full synthetic; proper oil is particularly important to protect the turbocharger and direct-injection system.
• 3.2 FSI V6 (Gasoline): Typically VW 502 00 synthetic, often 5W-40; check manual for climate-specific viscosity guidance.
• Diesel TDI variants (in Europe and other regions): Usually VW 507 00, 5W-30 low-ash oil for DPF compatibility and longer service intervals.

In practice, many workshops use a single VW 504/507-approved 5W-30 oil that covers both gasoline and diesel A5 models, provided it meets the official specs listed for the specific engine.

2009 Audi A6

The 2009 Audi A6 range includes four-cylinder, V6, and some higher-output engines, both gasoline and diesel, and thus spans multiple VW oil standards.

The following list captures typical oil specifications for core A6 engines.

• 2.0 TFSI / 2.8 FSI / 3.2 FSI (Gasoline): Commonly VW 502 00 (and sometimes VW 504 00 for LongLife), with 5W-40 or 5W-30 full synthetic recommended.
• 3.0 TFSI V6 (Supercharged, where fitted in late 2009 in some markets): Typically VW 502 00 or VW 504 00; high-quality synthetic 5W-40 or 5W-30 is used due to added stress on the supercharged engine.
• 2.0 TDI / 2.7 TDI / 3.0 TDI (Diesel): Usually VW 507 00-compliant 5W-30 low-SAPS oil to protect DPF and meet emissions standards.

Given the range of engines, checking the specific engine code (listed in the service booklet or trunk sticker) is the most reliable way to confirm the exact oil specification for a 2009 A6.

2009 Audi Q5 and Q7

For Audi’s SUVs, engines are often closely related to those in the A4 and A6, including both gasoline and diesel powertrains, and they share similar oil requirements, especially regarding VW 502 00 and 507 00 standards.

The list below provides a general guide for typical 2009 Q5 and Q7 engines.

• Q5 2.0 TFSI / 3.2 FSI (Gasoline): Usually VW 502 00 (or VW 504 00), with 5W-40 or 5W-30 full synthetic oil suitable for heavy use and towing.
• Q5 and Q7 TDI Diesels (e.g., 3.0 TDI): Typically VW 507 00 5W-30 low-ash oil, critical for protecting the DPF system under heavier SUV duty cycles.

Because SUVs often see more load and towing, adhering to the correct spec and change interval is especially important to prevent thermal breakdown of the oil and premature engine wear.

2009 Audi S- and RS-Models (Performance Variants)

Performance models such as the 2009 S4, S5, and, in some markets, RS variants, operate at higher temperatures and loads, but they still rely primarily on the same VW 502 00 or 504 00 specifications, with strict adherence recommended.

The following list highlights common requirements for key performance models of that year.

• 2009 S5 4.2 FSI V8: Typically VW 502 00 full synthetic, commonly 5W-40; some markets also allow 0W-40 if it meets 502 00, especially in colder regions.
• Early 2009 S4 (B7, 4.2 V8, where still sold) / Late 2009 S4 (B8, 3.0 TFSI): Generally VW 502 00 (sometimes VW 504 00), 5W-40 or 5W-30; high-quality synthetic is critical due to high RPM and performance use.
• RS Models (where applicable): Usually require VW 502 00 or higher, often in 5W-40; some owners and workshops opt for higher-temperature-rated oils as long as they remain within VW-approved specifications.

Because performance engines are more sensitive to lubrication quality, many owners choose to change oil more frequently than the maximum interval, even when using manufacturer-approved LongLife oils.

How to Confirm the Correct Oil for Your Specific 2009 Audi

Even within the same model year, small differences in engine code, market, and emissions equipment can alter the exact oil specification. To avoid guesswork, it is best to verify using the documentation and labels that apply directly to your vehicle.

Practical Steps to Identify the Right Oil

The following list outlines straightforward steps to ensure you select the correct oil for your specific 2009 Audi.

1. Check the Owner’s Manual: Look for the section labeled “Engine oil” or “Lubricants,” which will list the required VW standard (e.g., VW 502 00 or VW 507 00) and recommended viscosity.
2. Inspect Under-Hood Labels: Some 2009 Audis have a sticker on the underside of the hood, near the radiator support, or on the oil filler cap indicating the required oil standard.
3. Locate the Vehicle Data Sticker: In many Audis, a data sticker is found in the trunk (spare wheel well) or inside the service booklet; it includes the engine code, which can be cross-referenced with Audi or dealer data.
4. Use Manufacturer or Dealer Websites: Many official Audi websites or dealer portals allow you to enter your VIN to retrieve precise lubricant specifications.
5. Verify on the Oil Bottle: When buying oil, ensure the label clearly states compliance with the exact VW standard (e.g., “Approved VW 502 00/VW 505 00” or “VW 504 00/507 00”) rather than only listing generic API or ACEA ratings.

By following these steps, you can confirm you are using oil that is fully compatible with your specific 2009 Audi engine and regional requirements, rather than relying solely on generic recommendations.

Oil Change Intervals for 2009 Audi Models

In 2009, many Audi models supported two types of service regimes: fixed (time/mileage-based) and flexible (LongLife) intervals, depending on region and dealer setup. The type of interval used influences both the oil spec and how often it should be changed.

Typical Service Interval Ranges

The following list provides a general guide to recommended oil change intervals for a 2009 Audi, assuming correct oil specification and normal driving conditions.

• Fixed Interval Service: Typically every 10,000 miles (about 15,000 km) or 12 months, whichever comes first, using VW 502 00 or equivalent oil.
• Flexible/LongLife Service: In some markets, up to approximately 18,000–20,000 miles (30,000 km) or up to 2 years, with on-board monitoring, using VW 504 00/507 00 LongLife oils.
• Severe or Harsh Conditions: More frequent changes (for example, every 5,000–7,500 miles or 8,000–12,000 km) are often recommended for heavy city driving, frequent short trips, high-performance use, towing, or very dusty conditions.

While LongLife intervals are supported by Audi, many independent specialists advise shorter intervals—especially for turbocharged and high-performance engines—to enhance long-term reliability and reduce carbon buildup.

Compatible Brands and Labeling to Look For

Several major oil brands produce products that officially meet VW 502 00, 504 00, and 507 00 standards. When choosing a brand, the most important factor is the VW approval printed on the bottle, not just viscosity or generic quality claims.

Recognizing VW-Compliant Oils

The following list provides guidance on identifying and choosing properly approved oils for your 2009 Audi.

• Look for VW Approval Text: The label should clearly state “VW 502 00,” “VW 504 00,” or “VW 507 00,” sometimes alongside older specs like “505 00.” Wording such as “Suitable for” or “Recommended for” is not the same as formally “Approved.”
• Common Reputable Brands: Major names such as Castrol, Mobil 1, Shell (Helix), Liqui Moly, TotalEnergies, Motul, and others sell VW-approved oils in the correct viscosities.
• Combined 504 00/507 00 Oils: Many modern full-synthetic 5W-30 oils carry both VW 504 00 and 507 00 approvals, making them compatible with a wide range of 2009 Audi gasoline and diesel engines where these specs are listed.
• Verify Against Audi Documentation: Even with brand-name oils, always confirm the approval code matches what is specified in your manual or on the under-hood label.

By prioritizing VW approval codes over marketing terms, you ensure the oil meets Audi’s engineering requirements for your specific 2009 engine design.

Summary

A 2009 Audi typically requires fully synthetic engine oil that meets Volkswagen Group’s official standards, most commonly VW 502 00 for gasoline engines and VW 507 00 for modern diesels with particulate filters, with VW 504 00 also used for some LongLife gasoline applications. The most frequent viscosities are 5W-40 and 5W-30, selected according to climate and service regime. Because variations exist across models and markets—from A3 hatchbacks to Q7 SUVs and S/RS performance cars—the safest approach is to confirm the exact VW oil specification in the owner’s manual, on under-hood labels, or via VIN-based lookup, and then choose a fully synthetic oil whose label explicitly lists the required VW standard.
