Fuel Does It Matter Which!

I know its not Europe but my running mate did 27yrs with the main fuel hauler in western Canada and a couple o yr after retiring with a smaller company…well I asked him why he never fueled up at a certain retail companies locations and he told me …"every yr the refinery he ran out of shut down /cleaned out so many storage vessels in the winter (think -20c ish) and this certain retail company would buy the contents sometimes diesel/petrol/avgas and my mates company would come in mob handed and empty the vessels out and take to whatever locations they were told. He told me it was a miserable job as the petrol/diesel/avgas had so much condensation in it froze in the pipes when pumping out. Can only take this at face value as he is not known for telling tall tales. :grimacing: This retail company fuel is always a couple o cents cheaper than everyone else.
