My 2019 A8l 3.0 Is up for an oil change. I can find a bunch of different answer for the right viscosity, my question is is there any reason I can't use 5W-20 (ravenol,so meets Audi spec) for a late summer Into winter oil change up here in Michigan? I have an entire oil change kit from my D4 that I didn't use and I would hate to buy another 8 things of oil.

Appreciate any thoughts!

What oil spec is required by your 2019 A8?

There's a 5W20 that meets the EA839 oil spec?!

Is it a different species that for the D4engines?

If so I will just buy the right stuff

Yeah the new Audi engines (V6s) use 50800 oil.

My 2021 shows 0-20W

Fwiw, The V8's use 0w30\504 and recommend only Audis brand at $17\qt at my local dealership. Been using castrol whenever the add oil light comes on.

There is no point to use only $17/qt oil. Attached list has all kind of oils approved by Audi for 8 cyl. engine.

Just changed oil today on my 4.0 8cyl engine. I used suction method. Manual says this engine needs 10qt of oil. There were 8.5qt out and I put 9qt in.
Oil measurement on the dash says the oil level is full. Does it mean that not all oil was sucked out ?

Thanks.

The 4.0L manual explicitly says not to extract oil (my apologies to the gentleman who posted a snapshot from the mechanic's manual - I forgot who posted it) using the method you mentioned.

However, in any event some discrepancy is normal. There already is some oil in the vanes of the engine bay, etc. That said, I personally wouldn't do an oil change that way...
