The 2019 Audi A3 typically uses fully synthetic engine oil that meets Volkswagen Group specifications, most commonly 5W-30 with VW 502.00 approval. Some engines or driving conditions may allow 5W-40 or VW 504.00 for longer-life intervals. Always verify the exact specification in your owner’s manual or on the oil cap.
Oil type and viscosity
The following options cover the most common oil viscosities and VW specifications used in the 2019 A3 lineup. The exact requirement depends on the engine variant and market, so consult your manual for the precise spec.
- 5W-30 synthetic oil that meets VW 502.00 specification (standard for many petrol engines in the 2019 A3).
- 5W-40 synthetic oil that also meets VW 502.00 specification (an alternative for certain engines or hotter climates).
- In some markets or service plans, oil meeting VW 504.00 may be specified for longer drain intervals; confirm with your manual.
In short, for most 2019 A3 petrol engines, 5W-30 synthetic oil with VW 502.00 approval is the default starting point, with 5W-40 as a viable alternative in selected cases. Always follow the exact spec listed by Audi for your VIN.
Where to find the exact specification
To identify the precise oil requirements for your vehicle, check these sources. They help ensure you use the correct viscosity and VW/Audi approval to maintain performance and warranty coverage.
- Owner’s manual, in the maintenance or lubrication section.
- Oil filler cap on the engine, which often states the required viscosity and approval.
- Service interval sticker or maintenance sheet from Audi or an authorized service center.
- VIN-based lookup on Audi/VW official portals or by consulting a dealership.
If any uncertainty remains after consulting these sources, contact an authorized Audi service center to confirm the exact oil specification for your vehicle.
How to perform an oil change or check
If you’re planning an oil change or simply checking the level, following a proper procedure helps ensure engine longevity and accurate readings. The steps below outline a typical process and should be adapted if you’re working on a recent model or if your manual provides different guidance.
- Warm up the engine briefly, then turn it off and wait a few minutes for the oil to settle.
- Park on a level surface, engage the parking brake, and place a pan under the drain plug.
- Remove the drain plug, let old oil drain completely, then replace the plug with a new crush washer if required.
- Remove and replace the oil filter, ensuring a proper seal and disposal of the old filter.
- Fill with the correct synthetic oil (viscosity and VW specification as specified for your engine), using a funnel to avoid spills.
- Check the oil level with the dipstick (or electronic gauge, if equipped) and top up as needed to the full mark.
- Run the engine for a few minutes, recheck for leaks, and re-check the oil level after a brief idle.
Always dispose of used oil and filters at a proper collection facility and update your service records to reflect the change.
Summary
For a 2019 Audi A3, the baseline recommendation is a fully synthetic oil that meets VW 502.00, with 5W-30 as the most common viscosity. Some engines or climates may permit 5W-40 or VW 504.00 for longer drain intervals, but you should verify the exact specification for your vehicle using the owner’s manual, the oil cap, or a dealership. Regularly checking oil level and following the manufacturer’s maintenance schedule helps protect the engine and maintain performance.
