Anyone seen black "goo" build up on their injectors from E85?

[QUOTE="ClubVenom1, post: 15204836, member: 47265"] This is what I pulled off of another car forum (evolution.net) and this is what one guy found out about the black goo. "Well, here is what I did just so everyone is clear. I filled a 40mL vial with E85 and blew it dry with nitrogen gas and mild heating (about 150*F). After there was no fuel left, I placed it under high vacuum to remove any remaining volatiles for about an hour. I was left with a clear sticky residue that smelled bad - like nasty frying oil. I dissolved this sample in the NMR solvent and analyzed it and it IS the same goo that was on the injector. There was smaller amounts of some other stuff in it as well, but the same peaks I saw in the black goo were in this residue. The black goo IS coming from the E85. It isn't naturally black, though. I suspect it just has soot mixed in with it that is giving it the color. So the next challenge is figuring out why is this crap in our fuel, and if it is in everyone's fuel (particularly people who aren't having this problem). " Heres the link [URL="http://www.codsm.org/forums/showthread.php?t=3965"]http://www.codsm.org/forums/showthread.php?t=3965[/URL] LOL maybe thats why its so detonation resistant... because of all the sticky gel floating around in the combustion chamber, cushioning the ignition, as if the flame is enveloped in micro bubble wrap.
