What Kind of Oil Does a 2020 Audi A3 Take?

A 2020 Audi A3 requires full synthetic engine oil that meets Audi/VW specification VW 502 00 (or VW 504 00 for some long‑life service markets), typically in SAE 0W‑40 or 5W‑40 viscosity, depending on climate and engine variant. Always confirm with the owner’s manual or the label under the hood for the exact spec and viscosity for your specific engine code.

Understanding the Official Oil Specification

The central requirement for a 2020 Audi A3 is not just the viscosity (like 0W‑40) but the manufacturer standard: VW 502 00 or VW 504 00. These specs define performance thresholds for wear protection, detergency, and compatibility with Audi’s turbocharged engines and emission systems.

Primary Audi/VW Oil Standards for the 2020 A3

The following list explains the main Volkswagen Group oil standards you’ll see on bottles suitable for a 2020 Audi A3.

• VW 502 00: The most common spec for gasoline (petrol) Audi engines in North America and many other markets; designed for high‑performance, turbocharged engines with standard service intervals.
• VW 504 00: A more advanced “long‑life” spec used in some regions (especially Europe) where extended oil change intervals are approved and low‑SAPs (low ash) formulations are required.
• VW 505 00 / 507 00: Primarily for certain diesel engines and long‑life service; relevant only if you own a 2020 A3 TDI in markets where it was sold.

Together, these standards ensure the oil can cope with high temperatures, turbocharger demands and protect internal components over the recommended service interval. For most gasoline 2020 A3 models, VW 502 00 is the essential label to look for, with VW 504 00 acceptable where specified.

Recommended Viscosity Grades

While the specification guarantees performance, viscosity determines how the oil flows in different temperatures. Audi approves several SAE grades for the 2020 A3, but 0W‑40 and 5W‑40 are the most common and practical for modern turbocharged engines.

Typical Viscosity Recommendations

This list shows commonly recommended viscosities for a 2020 Audi A3 and their general use cases. Final choice should follow the owner’s manual and regional guidance.

• 0W‑40 (VW 502 00 / 504 00): Ideal for colder climates, providing fast lubrication at cold start while remaining stable at high operating temperatures.
• 5W‑40 (VW 502 00): Widely used in moderate to warm climates; offers robust high‑temperature protection for turbocharged engines.
• 0W‑30 or 5W‑30 (VW 504 00 / 507 00): Sometimes specified in Europe for certain engines with long‑life service intervals and stricter emissions requirements.

Across these options, the priority is that the oil carries the correct VW/Audi specification; viscosity can then be chosen based on climate and usage within the options listed in your manual.

Gasoline vs. Diesel: Engine-Specific Needs

The 2020 Audi A3 was sold with several powertrains worldwide, including turbocharged gasoline engines (like the 1.4 TFSI / 1.5 TFSI and 2.0 TFSI) and, in some markets, TDI diesels. The correct oil spec varies slightly depending on fuel type.

Gasoline (TFSI) Engines

Most 2020 Audi A3 models sold in North America and many other regions are equipped with turbocharged gasoline engines, which place high demands on oil due to elevated temperatures and turbocharger lubrication needs.

The list below covers key points for oil in 2020 A3 gasoline engines.

• Standard spec: VW 502 00 full synthetic motor oil is the baseline requirement for most 1.4/1.5 TFSI and 2.0 TFSI engines.
• Common viscosities: 0W‑40 and 5W‑40, depending on climate and market guidance.
• Turbo protection: Oils must resist coking and breakdown at the high temperatures found in turbo bearings.
• Deposit control: The oil’s detergent package helps keep intake valves and pistons cleaner in direct‑injection engines.

As long as the bottle clearly states compliance with VW 502 00 (or VW 504 00 when specified in your manual), and viscosity fits the climate guidance, it will be suitable for a 2020 A3 gasoline engine.

Diesel (TDI) Engines

In some markets, the 2020 A3 was available with TDI diesel engines, which require oils compatible with particulate filters (DPF) and often longer service intervals.

The following points outline what diesel‑equipped A3 owners should look for.

• Core specs: VW 504 00 / 507 00 low‑ash (low‑SAPs) oils are typically required for TDI engines with DPFs.
• Viscosity: Often 5W‑30 or 0W‑30, but check the exact recommendation in your regional manual.
• Emissions compatibility: Low‑SAPs formulations protect the DPF from ash buildup and maintain emission compliance.
• Extended intervals: In markets that allow LongLife servicing, these oils support longer change intervals when monitored by the car’s service indicator.

Because diesel lubrication needs and emissions equipment are stricter, using the exact VW 504 00 / 507 00 spec (if stated in your manual) is critical to avoid DPF damage and warranty issues.

Examples of Suitable Oils on the Market

Many major brands produce oils that meet VW 502 00 or VW 504 00 / 507 00. The key is to read the back label carefully rather than relying on generic “European formula” marketing terms.

Common Brand Examples (Check Labels for Specs)

This list provides examples of oil product lines frequently approved for Audi/VW specs, but always verify the exact spec on the bottle for your market and formulation.

• Castrol EDGE 0W‑40 or 5W‑40 with VW 502 00 / 505 00 approval (often marketed as “European Car Formula”).
• Mobil 1 ESP 0W‑40 or Mobil 1 0W‑40 FS in versions carrying VW 502 00 and/or VW 504 00 / 507 00 approvals.
• Liqui Moly Top Tec series (such as Top Tec 4200, 4100) with VW 502 00 / 504 00 / 507 00 approvals depending on variant.
• Shell Helix Ultra 0W‑40 or 5W‑40 variants certified to VW 502 00 and in some cases 504 00 / 507 00.
• OE-branded Audi/VW Genuine Oil sold at dealerships, typically 0W‑30, 0W‑40 or 5W‑40 with the correct VW spec printed on the bottle.

Because product lines and approvals change over time, it is essential to confirm the current approval list on the back label or the manufacturer’s website rather than assuming all variants of a given name meet Audi/VW standards.

Oil Capacity and Change Intervals

Knowing the right oil is only part of the equation; owners also need to know roughly how much oil the engine holds and when it should be changed.

Approximate Oil Capacity

The total oil capacity for a 2020 Audi A3 varies slightly by engine, but a general range is helpful for planning oil purchases.

The points below summarize typical capacities (including oil filter) for common 2020 A3 engines. Always confirm with the manual or service data for your specific engine code.

• 1.4 TFSI / 1.5 TFSI: Roughly 4.0–4.3 liters (about 4.2–4.5 US quarts).
• 2.0 TFSI: Typically around 5.0 liters (about 5.3 US quarts).
• TDI variants: Often in the 4.3–4.7 liter range, depending on engine and market.

These values help ensure you buy enough oil; however, always fill gradually, check the dipstick or electronic level readout, and adjust to the specified mark rather than relying purely on capacity figures.

Recommended Change Intervals

Service intervals for the 2020 Audi A3 are influenced by regional policy, driving conditions, and whether the car is set up for fixed or flexible (LongLife) servicing.

The following list outlines general guidance many owners follow, but local recommendations and warranty terms take priority.

• Fixed interval (common in North America): Oil change roughly every 10,000 miles (16,000 km) or 12 months, whichever comes first.
• Flexible/LongLife interval (common in Europe): Up to about 18,000–20,000 miles (30,000–32,000 km) or 2 years, when using VW 504 00 / 507 00 oil and with the car’s service indicator managing intervals.
• Severe use conditions: Frequent short trips, heavy city traffic, extreme temperatures or spirited driving may justify more frequent changes, such as every 5,000–7,500 miles (8,000–12,000 km).

Following the service indicator and using the correct VW‑approved synthetic oil are the best ways to protect the engine, turbocharger and emissions systems over the life of the vehicle.

How to Confirm the Correct Oil for Your Specific Car

Because trim levels, engines and regional emissions packages vary, the definitive answer for your exact 2020 Audi A3 is always in the official documentation and labels that came with the car.

Key Places to Check Before Buying Oil

The following sources will help you verify the correct spec and viscosity for your particular A3.

• Owner’s manual: The lubrication section lists approved VW specs (e.g., “Use engine oils conforming to VW 502 00”) and allowed viscosities by temperature range.
• Service booklet or maintenance guide: May include information on fixed vs. flexible intervals and the associated oil requirements.
• Under-hood or oil-cap labeling: Some cars have stickers or cap markings noting the required VW spec or general guidelines (e.g., “Use synthetic oil meeting VW 502 00”).
• Audi dealership or official service center: Can confirm the correct oil based on your VIN, engine code and market configuration.
• Trusted online databases: Manufacturer or major oil-brand “oil finder” tools, as long as they reference VW 502 00 / 504 00 / 507 00 explicitly.

Cross‑checking at least two of these sources helps ensure that the oil you choose is fully compatible with your engine and any remaining warranty coverage.

Summary

A 2020 Audi A3 requires full synthetic engine oil that meets Audi/VW standards—most commonly VW 502 00 for gasoline engines, with VW 504 00 / 507 00 used in some long‑life and diesel applications. Typical viscosities are 0W‑40 or 5W‑40 for TFSI gasoline engines, and 0W‑30 or 5W‑30 for many TDI diesels, always within the ranges listed in the owner’s manual.
