I used it when I had the 2017 Hyundai Sonata 2.4l. I don't have scientific evidence but it seemed like it had cleaned the engine out very good. The oil in that car would turn deep brown within the first 500-1000 miles, and I changed it every 4k using Quaker State Ultimate Durability/Ultimate Protection. Note here, I know color is not much of a reliable indication of anything but that's what I saw.
After the flush, the oil was almost too clean to see on the dip stick all the up until the accident, well past the 2000 mile mark. And granted, it had an oil consumption issue but that rarely made the oil in the system look artificially clean on the dip stick.
I'm just curious if anyone else has heard of it or used it, because it has raving reviews and I'm certainly impressed with it.
