I got a check engine light on this tank (roughly 37% ethanol).  It lit about 3/4 of the way through the tank, and cleared before I filled up again.

This is the pattern I've seen at higher ethanol levels with this car, the CEL lights late in the tank and then clears itself.

I will be increasing ethanol content on the next tank to see if the CEL lights earlier and stays on.
