The Audi A4 B7 uses synthetic engine oil that must meet Volkswagen Group specifications, and the exact grade depends on the engine in your car. In most cases, 5W-40 synthetic oil that meets VW standards is a safe starting point, but petrol and diesel engines may require different VW specifications (such as 502.00/502.01 for petrol or 505.01/507.00 for diesels). Always verify with your owner's manual or a dealer, and check the oil cap or service label for the exact requirement.
Petrol engines in the A4 B7
Oil choices for petrol variants depend on the specific engine code and market, but the pattern is broadly similar: use a high-quality synthetic oil that meets VW Group specifications. The most common baseline is 5W-40 synthetic in many A4 B7 petrol engines, with some engines tolerating 5W-30 under certain conditions.
Engine variants in the B7 petrol lineup
The B7 petrol lineup typically includes 1.8T, 2.0 FSI, and 3.2 V6 FSI variants. Each engine may have slightly different oil approvals or climate-based recommendations, so the exact specification should be confirmed for your car.
- Viscosity: 5W-40 synthetic is the most commonly recommended viscosity for many B7 petrol engines.
- VW specification: Oils that carry VW approved ratings such as 502.00/502.01 are typically suitable for petrol engines on the B7.
- Alternatives: In some climates or for specific engine codes, 5W-30 or other approved viscosities may be acceptable; verify with the manual.
- Capacity: Oil capacity varies by engine, generally around 4.0 to 5.0 liters (plus filter) depending on the exact model.
Concluding: For petrol A4 B7s, use a high-quality synthetic oil that meets VW 502.00/502.01 approvals and match the viscosity to your engine and climate, as confirmed by the owner's manual.
Diesel engines in the A4 B7
Diesel variants require different specifications, particularly if the car has a diesel particulate filter (DPF) or newer emission controls. Common practice is to use a long-life synthetic oil that meets VW Group standards appropriate to the year and engine code.
Engine variants in the B7 diesel lineup
Diesel options include 1.9 TDI and 2.0 TDI, with some markets offering 2.7 TDI and 3.0 TDI. Oil approvals vary by engine and production year, especially between pre-DPF and DPF-equipped models.
- Viscosity: 5W-40 synthetic is a common default for many diesel B7 engines.
- VW specification: Many diesel B7 engines require VW 505.01, while later or DPF-equipped engines may call for VW 507.00 (or 504.00 in some cases) depending on year and market.
- DPF considerations: If your car has a DPF, choose a low-SAPS (low sulfur, ash, and phosphorus) oil approved for that use.
- Capacity: Oil capacity for diesels typically ranges from about 4.5 to 6.0 liters, depending on the engine family.
Concluding: For diesel A4 B7s, confirm the exact VW specification for your engine and climate, and use a long-life, low-SAPS synthetic oil if a DPF is present.
How to confirm the exact oil for your vehicle
Because the B7 platform used multiple engines across markets, the safest approach is to consult the owner's manual, check the oil cap for a VW specification stamp, review the service booklet, or ask an Audi dealer or certified technician for the precise oil grade and specification for your specific engine code and market.
Summary
The Audi A4 B7 requires synthetic engine oil that meets Volkswagen Group specifications. The exact spec and grade depend on whether you have a petrol or diesel engine and on the engine code. Petrol engines are typically best served by 5W-40 synthetic oil that meets VW 502.00/502.01, while diesel engines often require 505.01 or 507.00 (with low-SAPS oil if a DPF is present). Always verify the correct grade and spec from the owner's manual, the oil cap, or a qualified technician to ensure performance and warranty compliance.
Does the Audi A4 take 5W-40 oil?
The Audi A4 compact sport sedan is powered by a potent turbocharged engine that requires full-synthetic 5W-30 or 5W-40 engine oil. Your owner's manual will have details on the recommended oil type for your specific Audi A4 model. The Audi A4 oil change schedule is every 10,000 miles or 1 year, whichever comes first.
Can I put 5W-30 in my Audi A4?
That said, the most recent Audi A4 models are recommended to use an oil that meets the VW 504 00 standard. When translated to equivalent Society of Automotive Engineers (SAE) viscosity grades, this means using a full-synthetic SAE 5W-30 or SAE 0W-30 oil.
Which oil does the Audi A4 use?
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.
