Does the CarbX work @ 640:1? Or is it designed to work at the typical ratio a two cycle water cooled engine calls for?

Of course it's designed to be utilized at the common 50:1 outboard ratio. However, at 640:1 (or at richer mixture in diesel applications), TC-W3 functions well as a fuel system lubricant (pumps, upper cylinder, etc.), and I see no reason CarbX wouldn't perform likewise, albeit at maintenance dosing levels of effectiveness.

in theory, it may help with DI deposits on the intake valves, where some engines, the EGR function is done via valve timing.

EVERY additive works, the question you should be asking is what is in it ?? 99.999% of all additives on the market have the same ingredients of paint strippers and paint thinners. With ULSD having even less lubrication, why in the world would anyone put a solvent in their fuel ??? As a maintenance director I've found a quality product that has ZERO solvents in it, actually it's synthetic based. Before you try any additives, READ WHAT'S IN THEM !!!!!

I just have trouble wrapping my head around a product that was designed to work at a 50:1 ratio working at a ratio over 12 times less. I see it benefiting the pump, and possibly the injectors in diesel apps, even diluted to 640:1. But at a concentrate diluted by over 12 times I can't see it doing much in terms of breaking down carbon. Opinions vary.

Costco's fuel detergent has undergone testing where it goes beyond keep clean. But this takes place over several thousand miles. I'm not exactly sure what additive it is but like many fuel additives such as PEA, it could be a weaker form of a fuel system cleaning concentrate.

Referring to this page presented by the OP: http://www.saltwatersportsman.com/techniques/understanding-two-stroke-engine-oil
Quote:
"All of the oils contain some amount of polyisobutylene, or PIB, as part of the additive package," said Jeffery Hsu of Pennzoil-Quaker State. "It replaces some of the brightstock, which is good for lubricity, but bad for smoke. PIB burns very cleanly, but if you use too much it turns into gummy residue deposits in the combustion chambers." Actually, it can be really gummy, similar in consistency to glue that has almost dried.
PIB has received some interest here at BITOG. But a statement in the paragraph above has a seeming contradiction that may simply be a warning against overdosing: "PIB burns very cleanly, but if you use too much it turns into gummy residue deposits in the combustion chambers." How do we end up with gummy residue if it burns cleanly? Is it because when there is too much in the gasoline it doesn't burn completely?
