What Kind of Oil a 2014 Audi A6 Quattro Takes

A 2014 Audi A6 Quattro typically requires fully synthetic engine oil that meets the VW 502 00 specification, most commonly in a 5W-40 or 5W-30 grade, depending on engine variant and climate. This oil standard is critical for proper lubrication, turbocharger protection (where applicable), and long-term engine durability, and should always be confirmed against the owner’s manual or an Audi dealer by engine code and market.

Understanding the Oil Requirements for the 2014 Audi A6 Quattro

The 2014 Audi A6 Quattro can be equipped with several engines—commonly turbocharged four-cylinder (2.0T), supercharged V6 (3.0T), and in some markets diesel variants (TDI). While the viscosity (e.g., 5W-40) may vary slightly, what really matters is that the oil meets Audi/VW’s own approvals, primarily VW 502 00 (for gasoline engines) or VW 504 00/507 00 for certain long-life and diesel applications. Using oil that meets these specifications is more important than brand loyalty, because the spec covers detergents, resistance to breakdown, and compatibility with emissions systems.

The Official Audi/VW Oil Specifications

Audi, under the Volkswagen Group, uses its own oil standards that go beyond the generic API or ACEA ratings printed on many oil bottles. These internal specifications are the key requirement for your 2014 A6 Quattro, and any oil you choose must clearly show one of these approvals on the label.

Core Specs for 2014 Audi A6 Gasoline Engines

For most gasoline-powered 2014 Audi A6 Quattro models (such as the 2.0T and 3.0T engines), the primary factory requirement is a specific VW standard. The list below outlines the relevant specs you are most likely to encounter on oil labels in North America and Europe.

• VW 502 00: The main specification for many Audi gasoline engines of this era; required for normal service intervals in most 2.0T and 3.0T engines.
• VW 504 00: A “LongLife” spec for extended oil-change intervals in some markets, usually in conjunction with flexible service schedules.
• ACEA A3/B4: Often seen alongside VW 502 00; indicates a high-performance European oil standard suitable for high-load engines.
• API SN or later (SN Plus, SP): A general North American standard; useful as supporting information but not sufficient by itself without VW approval.

Understanding these specifications allows you to narrow down suitable oils quickly: the bottle should clearly show VW 502 00 or VW 504 00 approval, not just “recommended for” language without an actual approval statement.

Specs for Diesel (TDI) Variants

In some regions, the 2014 Audi A6 Quattro was offered with diesel engines. These engines impose different chemical and performance demands on engine oils, especially due to particulate filters and emissions systems.

• VW 507 00: The primary spec for many modern VW/Audi diesel engines with diesel particulate filters (DPF), compatible with long-life service intervals.
• VW 504 00/507 00 combo oils: Many premium European oils carry both approvals, making them suitable for mixed gasoline/diesel fleets.
• Low-SAPS/low-ash formula: Required to protect DPFs and other after-treatment hardware.

Diesel owners should be especially strict about the VW 507 00 approval, as using non-compliant oil can shorten the life of expensive emissions components and risk warranty or legal issues in markets where diesel emissions are tightly regulated.

Recommended Viscosity Grades (5W-40, 5W-30, and Others)

Once you have the correct VW specification, the next step is choosing the correct viscosity. Viscosity describes how thick or thin the oil is at cold-start and at operating temperature. For the 2014 Audi A6 Quattro, Audi commonly recommends 5W-40 or 5W-30, with some flexibility based on climate and specific engine variant.

Typical Viscosity for 2014 Audi A6 Quattro Gasoline Engines

Most gasoline 2014 A6 Quattro models in North America and Europe use a narrow band of viscosities when paired with VW 502 00 or 504 00 approvals. The following viscosities are the most commonly specified for this car.

• 5W-40 (VW 502 00 approved): Widely recommended for many 2.0T and 3.0T engines; offers robust protection at high temperatures and good cold-start performance.
• 5W-30 (VW 504 00 or 502 00 approved): Common in regions or models configured for extended service intervals or slightly better fuel economy.
• 0W-40 (VW 502 00 approved): Sometimes acceptable in colder climates; improves cold-start flow while maintaining high-temp protection.

The safest approach is to follow the exact viscosity shown in your owner’s manual or under-hood label, but if Audi lists several options, you can choose among them based on climate and driving style as long as the VW spec is met.

Climate and Driving Conditions

Driving environment can influence which viscosity works best within the set of oils Audi approves. While the manufacturer gives a range, real-world conditions can tilt the choice one way or another.

• Cold climates (frequent sub-freezing starts): 0W-40 or 5W-30/5W-40 with strong cold-flow performance may be recommended, depending on the manual.
• Hot climates and heavy driving: 5W-40 is often preferred for better high-temperature film strength under high-load conditions.
• Mixed city/highway with normal temps: Either 5W-30 or 5W-40 (with the correct VW spec) typically works, as long as it matches Audi’s chart for your engine.

While viscosity can be optimized for climate, sticking to the approved VW spec ensures that all other chemical and durability requirements are still met, which is far more critical than minor viscosity variations.

Examples of Suitable Oil Types and Brands

Multiple reputable oil manufacturers sell products specifically formulated to meet Audi/VW specifications. Brand names can change slightly by market, and product lines are updated periodically, but the VW approval printed on the label is your anchor.

Commonly Used Fully Synthetic Oils (Gasoline Engines)

The following examples represent categories of oils that, in many markets, carry VW 502 00 (and sometimes 504 00) approvals suitable for a 2014 Audi A6 Quattro gasoline engine. Always verify the exact approval on the current bottle or product data sheet, as formulations and certifications can change.

• Castrol EDGE 5W-40 (VW 502 00/505 00 approved versions): Frequently marketed in partnership with Audi/VW dealers in several countries.
• Mobil 1 ESP or FS formulas with VW 502 00 or 504 00/507 00: Certain 5W-30 and 0W-40 variants carry official VW approvals; check the back label.
• Liqui Moly Top Tec and Leichtlauf series: Several 5W-30 and 5W-40 oils are explicitly certified for VW 502 00 / 504 00 and commonly used by European independent Audi specialists.
• Shell Helix Ultra / Pennzoil Platinum Euro (VW-approved variants): Some Euro formulas, especially “Euro L” or “Euro 5W-40,” carry VW 502 00 or 504 00 approvals.

Brand choice is less important than the printed approval. Two different brands with VW 502 00 are generally equivalent in meeting Audi’s baseline requirements.

Oils for Diesel (TDI) 2014 A6 Quattro Models

For TDI models, selecting a low-ash oil that explicitly lists VW 507 00 is essential. The list below includes categories of oils—check labels and local availability.

• Mobil 1 ESP 5W-30 (VW 504 00/507 00): A widely available low-SAPS oil designed for DPF-equipped engines.
• Castrol EDGE Professional LongLife III 5W-30 (VW 504 00/507 00): Often sold at European Audi dealers for diesel and some gasoline engines.
• Liqui Moly Top Tec 4200 5W-30 (VW 504 00/507 00): A popular choice among independent European workshops servicing Audi TDIs.

For diesel owners, deviating from VW 507 00 can lead to DPF issues and potential engine or emissions system damage over time, so this spec should be treated as mandatory.

How to Confirm the Correct Oil for Your Exact A6 Quattro

Because Audi offered multiple engines, regional packages, and service interval strategies in 2014, the precise recommendation for your car can vary slightly. Verification is straightforward if you know where to look.

Checking Official Sources

To eliminate any doubt, you can cross-check the required spec and viscosity for your exact VIN and engine code through multiple channels. These options offer varying degrees of detail and convenience.

• Owner’s manual: The first reference; look for the “Engine oil” section, which normally lists VW 502 00/504 00/507 00 and a viscosity chart.
• Service booklet or under-hood sticker: Some vehicles have a label in the engine bay noting the required oil spec.
• Audi dealer or official service center: Provide your VIN and ask for the current oil specification and viscosity recommendation.
• Official Audi technical documentation (online in some regions): Accessed via Audi’s owner or service portals, which may show the same info as the manual but updated for superseded specs.

By confirming through at least one official channel, you avoid relying purely on generic online advice, which may be correct in general but not precise for every engine or regional configuration.

Oil Change Interval Considerations

Choosing the right oil is only part of the maintenance picture. How often you change it influences engine health as much as the specification itself, especially in turbocharged engines like those in many 2014 A6 Quattro models.

Fixed vs. Long-Life Intervals

Depending on market and dealer programming, your A6 Quattro may be set up for fixed or variable service intervals. Each approach has implications for oil life and the type of oil recommended.

• Fixed interval (often around 10,000 miles / 15,000 km or 1 year): Common in North America; VW 502 00 oils are typically used, and some owners opt for even shorter intervals for added safety.
• LongLife variable interval (up to ~30,000 km / 2 years in some EU markets): Requires VW 504 00/507 00 oils designed to remain stable over extended mileage and time.
• Severe use adjustments: Frequent short trips, heavy traffic, high heat, or towing may justify shorter change intervals than the maximum allowed by the car’s service indicator.

Even if the car supports long intervals, many independent specialists recommend somewhat shorter changes—especially on older, turbocharged engines—to reduce sludge risk and wear as the vehicle ages.

Key Takeaways for a 2014 Audi A6 Quattro Oil Choice

For owners of a 2014 Audi A6 Quattro, the essential point is that the oil must be a fully synthetic product carrying the correct VW approval—most commonly VW 502 00 for gasoline engines, or VW 507 00 for diesels—typically in a 5W-40 or 5W-30 viscosity, adjusted for engine type and climate. The exact details are in the owner’s manual and can be confirmed by an Audi dealer with your VIN. Choosing an oil solely on brand or generic SAE viscosity is not enough; the VW spec is the non-negotiable requirement that ensures the oil is built for your engine’s thermal, mechanical, and emissions demands.

Summary

A 2014 Audi A6 Quattro generally uses fully synthetic engine oil that meets Audi/VW standards, primarily VW 502 00 for gasoline engines and VW 507 00 for diesel variants, most often in 5W-40 or 5W-30 grades. Owners should confirm the exact spec and viscosity in the owner’s manual or with an Audi dealer, as engine variant and region can influence details. The VW approval printed on the oil bottle is more important than the brand name, and adhering to both the correct specification and sensible change intervals is critical to maintaining engine health and longevity.

Is 5W-30 ok for Audi?

Yes, many Audis can use 5W-30 oil, especially if it meets the VW/Audi oil quality standards specified for your engine, which you can find in your owner’s manual. While 5W-30 is often the recommended viscosity for moderate climates, other viscosities like 0W-40 or 5W-40 may be recommended for certain conditions or high-performance models. 
When 5W-30 is a good choice 

• Moderate climates: 5W-30 is a common recommendation that provides a good balance of fuel efficiency and engine protection in moderate temperatures. 
• Specific models: It is often specified for a wide range of Audi models, including some A3, A4, and A7 models. 
• Meets specifications: As long as the oil is a full synthetic and meets the specific VW/Audi oil quality specification (e.g., VW 502 00 or VW 504 00), it can be used. 

When to consider other options

• Cold weather: For better cold-start protection, 0W-30 or 0W-40 may be a better choice, especially in colder climates. 
• Warm or high-performance engines: 5W-40 may be recommended for high-performance engines or to provide extra protection in hotter climates. 
• Vehicle-specific needs: Always check your owner’s manual for the most accurate information for your specific model year and engine, as recommendations can vary. 

What kind of oil does an Audi Quattro take?

For most A4 engines, SAE 5W-40 grade motor oils are suitable, offering excellent protection in various temperatures. If this isn’t available, SAE 5W-30 or another motor oil with an alternative viscosity can be used as long as it adheres to Audi’s oil-quality standards.
