Complete Oil Specifications
Your 2022 Audi A6 equipped with the 3.0L TFSI V6 (EA839) requires 5W-30 full synthetic oil meeting VW 502.00 / VW 504.00 (ACEA C3) standards. VW 508.00 with 0W-20 is also approved as an alternative.

Why a VW Approval Is Required for This Engine
The EA839 is Audi’s premium V6 architecture, used across the A6, A7, A8, Q7, and Q8 lineup. Its twin-scroll turbocharger, direct injection, and Audi Valvelift System (AVS) variable valve lift create precise oil flow requirements that go beyond what standard API SP addresses.
VW 504.00 (ACEA C3, 5W-30) is the established primary specification and provides the full-temperature film strength that the EA839’s V6 bearing layout demands. VW 508.00 (ACEA C5, 0W-20) is the newer fuel-economy-oriented approval — it meets stricter low-SAPS limits and is compatible with the EA839 in all operating conditions.
Either path is correct. The choice between them comes down to availability and preference: VW 504.00 5W-30 oils are more widely stocked; VW 508.00 0W-20 oils deliver marginally better fuel economy.
Using generic API SP oil without a VW approval will:
- ❌ Not provide the additive chemistry required for AVS variable valve lift protection
- ❌ Fail to meet Audi’s turbocharger deposit protection requirements
- ❌ Risk warranty coverage issues if engine damage occurs
Audi-Approved Oil Brands
-
✅ Castrol Edge Professional LL III 5W-30 (VW 504.00)
-
✅ Liqui Moly Longlife III 5W-30 (VW 504.00)

The VW approval number must appear on the bottle label. Cross-check against the Audi/VW oil approval database (audi.com/oilspec) for currently licensed products — approvals can be withdrawn.
Severe Service Check
You need the 5000-mile interval if you:
- Operate in ambient temperatures consistently below 14°F or above 100°F
- Make frequent short trips under 5 miles where the engine does not fully warm up
- Drive in sustained heavy stop-and-go urban traffic
- Use the A6 for commercial or high-mileage fleet purposes
Installation Details
Drain Plug Torque: 22 ft-lbs The EA839 uses an aluminum oil pan with an M14 drain plug. The Audi-specified drain plug with integrated gasket (N91118101) should be replaced rather than reused. Do not overtorque.

Pro Tip: The EA839 oil filter housing is accessible from the top of the engine on the A6 C8. A 27mm socket or Audi special tool 3417 fits the housing cap. Torque the cap to 18 ft-lbs after installing the new cartridge. Pre-fill the cartridge before installation to minimize the oil pressure build-up time on the first start after service.
FAQs
What oil does a 2022 Audi A6 3.0T TFSI take? 5W-30 full synthetic oil meeting VW 502.00/504.00 (ACEA C3). VW 508.00 with 0W-20 is also approved.
How many quarts does it need? 6.9 quarts with a new filter, 6.4 without.
What’s the difference between VW 504.00 and VW 508.00 for this engine? VW 504.00 specifies 5W-30 with ACEA C3 chemistry. VW 508.00 specifies 0W-20 with ACEA C5 (lower SAPS, better fuel economy). Both are approved for the EA839 — use whichever is available with a verified VW approval number.
Can I use generic API SP 5W-30? No. API SP alone does not meet VW 502.00/504.00 chemistry requirements for the AVS and turbo system. A VW-approved product is mandatory.
How often should I change the oil? Every 10000 miles or 12 months under normal driving. The OBD service indicator may extend or shorten this based on actual driving data.
