"Much of the technology in this segment has a very toxic profile, so we developed a product that offers significant performance benefits over current technology while concentrating on formulations that are better for the environment – and safer for users and engines," said Dr. David Turcotte, Valvoline technical director. "With our All Engine Clean Intake Cleaner, we think we accomplished this mission."

Walmart peddles this at a price WAAY under the competition, especially with a PYB oil change--at least last time I checked. Anyone have any experience with it? About a quarter of what a dealer charges for Berryman IIRC.

Here is the patent

http://www.freepatentsonline.com/y2019/0359914.html

BACKGROUND OF THE INVENTION
Gasoline direct injected engines directly add fuel to the combustion chamber bypassing the intake valves for efficient combustion. Some of the exhaust and crankcase vapor gas is recirculated back to the air intake and over the intake valves. This can cause a buildup of a carbonaceous material on and around the manifold and air intake valves, which eventually decreases fuel efficiency and performance.
Some of this deposit can be removed by adding a cleaning composition into the air intake. Current cleaning compositions that are generally organic solvent-based are suitable only for gasoline engines and are unsuitable for diesel engines. The fuel value of the solvents causes unintended increases in engine acceleration, sometimes resulting in damage from uncontrolled or run away combustion.

The above formulation was tested on a direct injected gasoline Hyundai Sonata (2.4 L GDI engine) with 26,808 miles. There were significant black deposits on the intake valves. As the car was running, the 44 oz of the above formulation was used in induction cleaning. The cleaning process resulted in cleaner intake valves. The above formulation was also tested on a direct injected gasoline Hyundai Sonata with 27,217 miles. There were significant black deposits on the fuel rails and piston tops. The cleaning process on the piston tops was after the fuel rail treatment and was conducted without induction cleaning. The cleaning process resulted in cleaner fuel rails and piston tops.

*How much cleaner though? (assuming this patent is talking about the same thing)
