Step-by-Step Instructions
Follow these steps carefully
1
Prepare (VW 508 00, NOT 502!)
The 2019–2024 A6 (C8, 2.0T) takes VW 508 00 0W-20 ONLY — NOT 502 00 (5W-40, for 2009-2018 Audis). You need 508-approved 0W-20 (buy 6 qt, use ~5.5), a new filter, drain pan, funnel. Capacity ~5.5 qt.
🔧 Mechanic's note — Tom Becker
I've learned: 508, not 502 — that's the whole guide. The 5W-40 jug from your old A4 will hurt this engine. Read the spec on the bottle, not the shelf price.
2
Drain from Plug (not extractor!)
Position the drain pan and remove the drain plug — let the old oil drain (expect ~5.5 qt). Don't use an extractor from above — it only gets ~3 qt. Drain from the plug.
🔧 Mechanic's note — Ray Delgado
I make it a point to skip the extractor on this one — owners only pull three quarts from above. Drain plug or you're leaving half the old oil in the pan.
3
Replace Oil Filter
Remove the old oil filter. Install the new filter — hand-tighten plus a quarter turn (or to spec for cartridge). Ensure the old gasket/element came out. Use the correct filter for the C8 2.0T — the turbo needs clean oil.
4
Reinstall Drain Plug
Reinstall the drain plug. Torque spec wasn't verified — tighten snugly (don't over-tighten the aluminum pan). Snug with a new washer is safe.
5
Add ~5.5 Quarts (508-spec 0W-20!)
Add ~5.5 quarts (5.2L) of VW 508 00-approved 0W-20 through the filler cap. Use ONLY 508-spec 0W-20 — not 502-spec 5W-40. The 2019+ 2.0T was designed for the thinner 508 oil. Pour slowly. Check the dipstick/electronic level after filling.
6
Check Level and Leaks
Start the engine — check for leaks and recheck the oil level; the 2.0T should idle smoothly. Follow the service indicator (typically 10,000 miles / 1 year with 508 oil). The 3.0T V6 is a different engine.
All Done!
Test your repair before closing everything up. If something doesn't work right, double-check your steps.
⚠️ Common Mistakes to Avoid
- • Not allowing the engine to cool before starting the oil change
- • Using the wrong type or amount of oil
- • Failing to replace the drain plug washer, leading to leaks
