Excessive Oil consumption

I have a 2018 3.0 Prestige with 114,000 miles and it has been going thru oil at a rapid pace ( 4 quarts between oil changes @ 10K miles) Any one experiencing the same issue?

I don't have the same issue, but have had previous cars (non-Audi) with such problems. You obviously have a leak somewhere (an obvious statement I know!) - I suggest it's either inside the engine (a good indication of this is blueish smoke from the exhaust) or an external leak outside the engine, for which you'll need to try and see if there's oil visible over some of the lower engine parts. Better still raise the car, remove the engine underbody tray/cover, and you'll get a much better view of external leaking under the engine. Don't forget that external oil leaks can get blown backwards with airflow when driving (depending where they are), so if you do see oil externally, try and trace the source from where the oil is towards the front of the car.

Where are you located?
I believe US 2018 A6 is a C7 with 3.0T s/c with Alusil block.
RoW 2018 is the C8 with 3.0T Turbo and the block should be sleeved and have less/no consumption, unless there are ring/piston problems.
I'd have it checked asap. 4 qts/10k miles is not normal.
Also with 114k miles in just 3-4 years you should be in the extreme service category, back in the day when they made that distinction. IMO that is still relevant today. Drive a million miles in the Sahara all day, then you might need more frequent service to prevent these kind of issues.![Wink](https://www.audiworld.com/forums/images/smilies/wink.gif)
Really might be too late now....

If it is a C8, early ones had a problem with a leak and there was a TSB for that, but being out of warranty a TSB is not covered, though it could help point to the problem area.

I think have a problem with my 3.0 TDI (286hp) with oil consumption because I changed it last week the oil at the service (now the car has around 70k km). When I took the car from service the oil level was at MAX level, and now after ~300km the oil level is around 3/4. Should I be worried?
Do you have to fill oil from one change to another?
Thanks!
