The engine typically uses a fully synthetic oil that meets VW/Audi spec VW 502.00, most commonly in 5W-40 viscosity.
For a 2009 Audi A4 with the 2.0-liter turbo (2.0 TFSI), the manufacturer generally approves a synthetic oil that conforms to VW 502.00 (with some markets also recognizing related specs for longer service intervals). The usual recommendation is 5W-40, though some climates or service plans may allow alternatives such as 5W-30 or 0W-40 if the manual or dealer specifies them for your VIN. Always verify the exact requirement in the owner's manual or with an Audi/VW dealer, since small variations can exist by market and engine variant. The typical oil capacity with a filter change is roughly 4.5 quarts (about 4.3 liters).
Oil specifications and recommendations
Key guidelines to follow when selecting oil for this model.
- Viscosity: Typically 5W-40 synthetic oil is recommended for the 2.0 TFSI engine in the A4.
- Specification: Look for oil that meets VW 502.00 (and compatible 505.00) standards as applicable to your VIN and market.
- Oil type: Fully synthetic oil only; avoid mineral or conventional blends for this engine.
- Oil capacity: About 4.5 quarts (roughly 4.3 liters) with a new filter; exact capacity can vary slightly by engine variant and filter choice.
- Branding: Choose a reputable brand that explicitly lists VW 502.00 (or 505.00) approval on the label.
In short, demand a synthetic oil that meets VW 502.00 with a 5W-40 viscosity as the standard starting point, and always confirm the precise spec for your vehicle’s VIN against official documentation.
Capacity and maintenance intervals
Understanding capacity and service intervals helps you plan maintenance without surprises.
Oil capacity and service intervals depend on engine variant and the user’s service plan. The typical refill amount after draining and filter replacement is around 4.5 quarts. Use the car’s onboard oil-life monitor or the owner’s manual to determine when to change the oil, and ensure the chosen oil continues to meet VW 502.00 (or other approved spec) for that interval.
Oil change checklist
Before performing or scheduling an oil change, keep these steps in mind.
- Verify the exact oil specification and viscosity required for your VIN (usually VW 502.00 and 5W-40).
- Gather a fully synthetic oil of the correct grade and a new oil filter approved for the engine.
- Warm the engine, drain the old oil, replace the filter, and refill with the recommended amount.
- Check for leaks and recheck the oil level after the engine runs and cools briefly.
- Record the service date and mileage in the vehicle’s maintenance log.
Following the correct spec and procedure ensures optimal protection for the turbocharged 2.0 TFSI engine and maintains performance.
Summary
For a 2009 Audi A4 2.0 T, the standard oil choice is a fully synthetic oil that meets VW 502.00, with 5W-40 being the typical viscosity. Always confirm the exact specification and capacity for your VIN in the owner's manual or with an Audi/VW dealer, since aftermarket variants can vary by market and engine code. Regular oil changes using the correct spec help protect the turbocharged engine and keep the A4 running smoothly.
