I'm hoping Honda did a better job on the overall engine design than Ford did on my F150 EcoBoost. This problem gets particularly bad if the vehicle is driven short distances and the engine doesn't have a chance to warm up and blow out any accumulated carbon. Moral of the story is drive it like you stole once in a while.That is only true in extreme cases where the engine has been neglected for an extended period of time, or is subject to a high amount of carbon buildup through poor design. When we get to that point, the only fix is a chemical soak followed by walnut media. In typical applications, say every 60K, the buildup is softened to an oily residue and wiped off (in small amounts) through normal operation where it's subsequently burned in the cylinders. Very similar to the way it accumulates over time. Anything that passes beyond that point is nothing more than harmless vapor/gas.
It remains to be seen as to how Honda is impacted by deposits, which is influenced mainly by poor quality fuel and long oil change intervals. But I suspect that the average Joe will maintain this car better than most other DI platforms (thanks in part to the maintenance minder).
This would be the right type of Seafoam applicator to use in DI:
