91 Octane

19t v1

I replaced a fuel injector in cylinder 6 with new decoupler and teflon seal. Car no longer shows a super knock code. I filled from almost empty to full at chevron but did not notice the ethanol content until I was looking at the log. The log is all the way up in second and I did not stop the log at the top. I stopped it after decelerating and shifting. I did the log on a road I was not completely familiar with. The ethanol content had not dropped to under 10 percent when I started the log. It was still going down. The car pulls very well.
