Review: Fixed Audi Oil Consumption on 3.0T (CREC) and 4.0T - I used this on our 2019 Q7 with the supercharged 3.0T V6 and 2017 S6 with the 4.0T V8 approximately 1 year ago. Both had AudiCare and oil was changed at 1 year or 10k miles while under warranty since new. Both started to have oil consumption issues around the same time (wife drives the Q7 and I work from home a lot) at 50k miles but were 'within spec' and about 1qt every 800-1k miles. I ran 2 bottles in each for 15 min and changed the oil, and have not had to add oil to either one until almost the 11 month mark on the S6 at just about 5k miles, and the Q7 lasted until the day before a planned oil change on them both at 12 months. It was a cheap test, and easier than doing the Berryman B-12 soak by far. Given that it worked, I believe both had stuck rings on the pistons. To keep the piston rings clean, I will continue to use the Engine Flush at each oil change.
