2wheelsforme has pretty well summed up my feelings as well. I use 87 octane almost exclusively. In areas with lower octane ratings (85 or 86) I use a mid range grade of fuel. I also will not use a station that is getting a fuel delivery because when they are dumping fuel it stirs up all the crap in the bottom of the tanks. I also avoid stations that do not seem to pump a high volume of fuel. I do quite a bit of riding in northern Arizona on the Navajo Reservation and I have gotten bad fuel there but for the most part the Hondas I have owned have all been pretty forgiving on the quality of fuel I put in them.

Good discussion
