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.

IT WON'T WORK FOR ME AT ALL !
Well for this brand it surprises me this product isn't good at all before my rating i did try in 3 vehicles and about 3 oil change of each, 2013 Audi Q7 TDI, 2002 Jeep wrangler and 1971 Pontiac GTO .WELL after following the instructions on it RUN the vehicles for about 20 minutes and drain the oil ,leave it for at least 20 minutes draining by the time get my coffee ☕️ than install new oil filter, plug and oil start the vehicles and i can tell when i check the synthetic oil level it wasn't that clear but in the Audi q7 tdi (diesel) from black oil went to black oil and this vehicle was my reason to buy this product when I order the first time I order the oil change kit from an euro website and everything was LiquiMoly more expensive than any other synthetic oil so I tough will be the best option for a long life for my Audi Q7 TDI. Well the car is gone now !

Use of this product is a good idea to help minimize sludge buildup.
Seems to have done a great job of cleaning my engine based on how dark the used oil was when I drained it, I believe I will continue using it at least once a year to help minimize sludge buildup.

Could be voodoo
Not sure if this does help much on the engine but I know it makes me feel better about driving long distance.
