| Capacity (without filter) | 5.1 quarts |
| Oil Filter | VAG 06L 115 562 B |
| Normal Interval | 10000 miles |
Why VW 508.00/509.00 Matters for the EA888
The 2023 Q3 uses the third-generation EA888 TSI with Active Cylinder Management, high-pressure and port fuel injection, and a variable-geometry turbocharger. Volkswagen’s 508.00 spec (for gasoline engines) mandates ACEA C5 chemistry: low-SAPS formulation to protect the three-way catalyst and gasoline particulate filter (GPF) from ash accumulation, while 0W-20 viscosity reduces cold-start friction in the variable-geometry turbo bearings and ACT solenoids.
Using incorrect oil will:
- ❌ Clog the gasoline particulate filter with excess ash deposits from high-SAPS oil
- ❌ Interfere with Active Cylinder Management by inadequately lubricating cylinder deactivation solenoids
- ❌ The older VW 502.00 / 504.00 specs (5W-30/5W-40) are not suitable for this generation engine
Audi-Approved Oil Brands
-
✅ Castrol EDGE Professional 0W-20 (VW 508.00)
-
✅ Mobil 1 ESP X2 0W-20 (VW 508.00)
-
✅ Shell Helix Ultra ECT C5 0W-20
-
✅ Liqui-Moly Top Tec 6600 0W-20
-
✅ Total Quartz INEO MDC 0W-20
The label must explicitly state VW 508.00 (or 509.00 for low-viscosity variants). Standard 5W-40 VW 502.00 oils used in older Audis do not meet this specification. Confirm the approval before purchasing.
Severe Service Check
Use the 5000-mile interval if you:
- Drive primarily in urban stop-and-go traffic
- Frequently use sport or sport+ driving modes
- Operate in extreme temperatures
- Make many short trips under 5 miles where the engine does not fully warm up
Installation Details
Drain Plug Torque: 25 Nm
Always replace the drain plug sealing ring (part: N 013 888 3) at every oil change. The aluminum oil pan threads strip easily if overtightened.

Pro Tip: The Q3’s oil filter is a cartridge element in a top-mounted housing on the engine. Use a 27mm oil filter cap socket to remove the housing — reinstall to 25 Nm. Audi’s Service Interval Display will show the remaining oil life percentage in the MMI system; the Flexible Service System can extend intervals beyond 10,000 miles in ideal highway conditions.
FAQs
What oil does a 2023 Audi Q3 2.0T take?
0W-20 full synthetic meeting VW specification 508.00/509.00 and ACEA C5. Do not use older VW 502.00 or 504.00 spec oils.
How many quarts does the Audi Q3 need?
5.5 quarts with a new filter, 5.1 without.
Can I use 5W-40 VW 502.00 oil from an older Audi in my Q3?
No. The 2023 Q3 EA888 Gen3b requires VW 508.00 (0W-20 ACEA C5). The 5W-40 VW 502.00 spec used in older Audis is not suitable — it’s too thick and the higher SAPS content will contaminate the GPF.
Is full synthetic required?
Yes. Only full synthetic oils can achieve both the 0W-20 viscosity grade and the ACEA C5 low-SAPS chemistry simultaneously.
How often should I change the oil?
Every 10000 miles or as indicated by Audi’s Flexible Service System, which can extend or shorten this based on actual driving conditions.
