Injector "gunk" and E-85

When I came across methylal in that post, I did some searching and it is indeed a real chemical, well at least that's what Wikipedia and other sites said. It's known by other names but it's proper name is Dimethoxymethane. This chemical is known to be a good solvent, which is probably why it was good at removing gunk caused by running E85. As far as to why it is no longer in use in fuel additives, that I am unsure of.
I too tend to trust findings in that forum due to the same reason you listed, but as with any advice given, gotta take it with a grain of salt.

According to the OP in that thread from GT-R Life that I quoted earlier, Gumout used to put methylal in their additive, but their formula has since changed and it is no longer used. No other fuel additive manufacturer that I know of uses this in their products so we're still back to where we started with this gunking issue.

Best we have here is 91 octane. However, E-30 is also available, advertised as being 92 octane. With E-30 in the tank the car flies, the difference is way more than noticeable. So, I am wondering, do you think running E-30, which I've grown fond of, can cause the injector gunk problem?

I can pull out my injectors and fuelab filter this month and take some pictures for science, they've only seen E-85 for 18 months of daily driving (city) in all weather conditions (-18 - 123F). Hell, if I get the timing right, I can send the injectors in for cleaning and flow rate analysis at the same time.

I wouldn't bet on the foam treatment because in my experience, the gunk buildup can be very substantial and require extended exposure to any cleaning agent. The fuel/crankcase treatement doesn't list PEA or PIBA as ingredient, so hard to say for it.
