Why do you run the cleaner at all? I ran a couple of Techrons through mine, but it sat for a year with old gas in it. Heck, I pulled the fuel pump, tore it apart and had to manually clean it.

What brand of gas do you use? I prefer to run Shell in everything. But I've heard that Marathon also doesn't run ethanol.

BP in my diesel.
