Audi A4 Oil Capacity & Oil Type
TL;DR
B8 2.0 TFSI (CAEB/CAED): about 4.6 L (4.9 qt). B9 2.0 TFSI: about 5.2 L (5.5 qt). Viscosity and capacity depend on the exact engine code, so verify with your owner's manual.
Audi A4 oil capacity by engine generation
The Audi A4 has been built across several generations (B6, B7, B8, B9), and each swapped engines - so there is no single correct oil capacity for every A4. Capacities below are verified for the engine codes shown; other engine codes are not listed here because we could not confirm their figures with a credible source.
B8 generation (2008-2016), 2.0 TFSI
Cars with the EA888 2.0 TFSI engine (codes CAEB and CAED, both quattro and front-wheel-drive) hold about 4.6 L (4.9 US qt) of oil with a filter change. Audi's spec sheets for this engine call for full-synthetic oil meeting VW 502 00, most commonly in 5W-40, though 5W-30 oils meeting the same spec are used by some service centers.
B9 generation (2016 onward), 2.0 TFSI
The newer EA888 2.0 TFSI used in the B9 A4 takes about 5.2 L (5.5 US qt) with a filter change. Audi approves both 5W-30 and 5W-40 oils here, provided they meet VW 504 00 (longlife) or VW 502 00.
Data table
| Engine code / years | Capacity with filter (L / US qt) | Viscosity |
|---|---|---|
| 2.0 TFSI, CAEB / CAED (B8, 2008-2016) | 4.6 L / 4.9 qt | 5W-40 (VW 502 00); 5W-30 also used |
| 2.0 TFSI (B9, 2016 onward) | 5.2 L / 5.5 qt | 5W-30 or 5W-40 (VW 504 00 / 502 00) |
Where to confirm the exact figure for your car
Engine codes and capacities changed even within a single generation. Before adding oil, check:
- The oil filler cap or the dipstick area, which sometimes lists the spec
- Your owner's manual, in the maintenance or fluids section
- The engine code stamped on the block or printed on the emissions/VIN sticker under the hood
- An Audi dealer parts lookup by VIN, which is the most reliable source

Frequently asked questions
How much oil does my Audi A4 take with a filter change?
It depends on the engine. B8-generation (2008-2016) 2.0 TFSI engines (CAEB/CAED) take about 4.6 L (4.9 US qt). B9-generation (2016 onward) 2.0 TFSI engines take about 5.2 L (5.5 US qt). Check your engine code before buying oil, since other A4 engines are not covered by these figures.
What oil viscosity does the Audi A4 2.0 TFSI need?
The B8 2.0 TFSI (CAEB/CAED) is specified for full-synthetic oil meeting VW 502 00, most often as 5W-40. The B9 2.0 TFSI accepts 5W-30 or 5W-40 meeting VW 504 00 or 502 00. Use the spec (VW number), not just the viscosity, when choosing an oil.
Why do different sources give different oil capacity numbers for the A4?
The A4 nameplate has covered several unrelated engine families across the B6, B7, B8 and B9 generations, and capacities changed between them and even between minor engine revisions. A number for one engine code is not valid for another, so always match the figure to your specific engine code.
Where can I find the exact oil capacity for my specific A4?
The most reliable sources are your owner's manual, the engine code stamped on the engine block, and an Audi dealer parts/service lookup using your VIN. These will always be more accurate than a general web figure.
