I think you meant to say “anything they can do to get the emissions down (full stop)”, as the increased efficiency continues outside of the factory too. Have you seen any evidence of increased engine wear? The web pages thrown up by a Google search seem to agree that there is no evidence of this in over a decade of use.Anything they can do to get the emissions down in the factory lol. And people wonder why engines don't last the mileage they used to. IMEO, 0w20 is too thin for anything other than a highly tuned engine.
I’ve made it a year without having to top up the oil. Perhaps, with modern manufacturing techniques, we are past the time of new engines needing a top up before the first service?The last two A3’s I had came with a bottle to top up the email, but not this one. Thinking about it, the last two also came with a paintwork care kit, again didn’t get it this time.
I didn't have to yet after 9 months, last time I checked the dip stick, still more towards the max rather than the min. Oil colour wise dark yellow (olive oil type). Assuming new oil is light yellow (sunflower oil)? My first car, after a year (diesel) the engine oil colour was very dark, more like balsamic vinegar.I’ve made it a year without having to top up the oil.

My first car was a Ford F-Series Super Duty, and I changed the oil on it about once a year. So when it was time to change the oil it wasn't exactly dark, but you could tell it was time to change it. It still depends on the quality of the oil. If you put good oil in it, it won't turn black like that. I used the best oil for 6.7 Powerstroke from the Valvoline Premium brand and it gave good results.I didn't have to yet after 9 months, last time I checked the dip stick, still more towards the max rather than the min.
