I've been following this on the Link board, and thought I'd see if anyone local has experienced this.
A few people have noticed some black oily/tar build up on the tips of their injectors after running E85. They said when they burn that black gunk, it smells like burning oil. So far no one seems to know what it is, or why it's there, including the people at FIC and RC.
It seems like the people having these issues are all running FIC injectors (not the new Bluemax ones). FIC is claiming that their Bluemax ones are E85 safe. But it's their older ones (1150's, white top 1600's) that people are getting this black oily/tar build up at the tips. I run the Blue Top ones from PTE, and mine are perfectly fine. I've put on quite a bit more miles then some of these others with the build up also. I personally have had no noticeable adverse affects from running E85 as of yet. It also sounds like people with both stock hard lines, and aftermarket fuel lines, are both having this issue.
Anyhow, I just find it interesting, and wondering if there's anyone here that's noticed this? If you have, please say what injectors, fuel lines, etc... you are running.
Here is one pic that kinda shows the gunk
And Here is the WORST case I've seen yet
