This Valvoline stuff is mixed with gasoline. Best case scenario is the ability to restore performance of clogged fuel injectors. Since a direct injection only engine does not introduce gasoline into the intake ports, I don't see how this chemical can reach the deposits on the intake valves.

Some say those don't work as well since they can't "reach" certain engine components. I did a brief look in to it and it seems Liqui Moly sells DI Jectron as well, which is supposed to penetrate deeper.
I'd look in to that a bit more since Liqui Moly is a pretty reputable brand. Not that Valvoline isn't but I think more enthusiast look to LM over others be it for oil or cleaners/additives.
$17 on FCP Euro, can't find it cheaper anywhere else.

The biggest issue with a direct injection only engine is the accumulation of combustion byproduct deposits on the intake valves, because the gasoline is introduced directly into the combustion chamber. Some manufacturers like Toyota and Ford employ direct AND port fuel injectors. The port fuel injectors circulate gasoline (an excellent solvent) around the intake valves to keep them clean.

Software programming determines when the port fuel injectors get energized. It's a compromised solution aimed to REDUCE deposit on the intake valves. I've seen these D-4S Toyota engines with +100K miles having 20-40% more deposit than the 343K engine (full time port injection) shown on the tear down video. Semi-aggressive highway speed driving (Italian tune up) will help control deposit formation in the engine. Avoid short distance stop and go driving.
Most well designed full time port injection engines (22R/Toyota truck, 1ZZ-FE/Toyota Corolla) with a steady diet of fresh regular non top tier fuel will look similar to the 343K engine at 200K and 250K miles. Direct injectors operate between 1000 and 3000 psi. The nominal operating pressure for port injectors is around 50 psi. Premature failure of direct injectors are beginning to show up on some modern Hondas.
