This thread stirs up memories of when I was in Australia, and I accidentally
filled up my Mini Moke with Diesel.  It ran fine at full throttle, but as I was
heading 4 hours out into the outback I headed back to the gas station,  The
old guy there sniffed the exhaust and asked if I'd filled up by myself ( a la self
serve) and I said that I had,  He then mentioned that he kept the diesel in the
tank hooked to the "Regular" pump ---  "most town folks knew that" he said.
Drained the tank - gave it back to him, and filled with regular and off I went.
Thanks for the opportunity to remember that slice of life.
