The oil is good for more than 5K. Don't worry about it any longer. Its not like you went to Jiffy lube and they put regen PZ 5W30 weasle wee in there.Edited to add: Checked oil last evening and its not green.
Rode up to Audi this morn: Svc Tech looked nr up and said its 0-20. Asked him why that nr is diff than one on qt. cans; he said he thought it was because it was bulk. Suggested I go talk to parts guy. I did and he said it was a bulk parts nr for 0-20 and they were diff nrs on qt cans.
I'll have to accept their word for it, but am still uneasy. At any rate, will change it out at 5K with 508.
I thought all approved VAG oil was dyed - but you wont see the green hue on the DS or used.
It should have a UV florescent tracer also - other VW fanatics correct me if I am wrong.
Maybe brig a few drops on a paper towel into the bedroom and hold it under the Frampton Comes Alive poster and KISS posters black lights
