So much for filters at the stations. Many have disagreed with me but IF stations have filters I think they do a poor job of replacing them. I have never seen filters being replaced while fueling and neither has anyone one I asked. Flying J, Pilot, etc would need a large bank of filters to filter the fuel. Filters at the pump, IMO, wouldn't do it. The number of trucks fueling at a pump in one day would dispense more fuel that many of us would use in a life time.
That's my story and I am sticking with it.:D
