[AT] OT: Gas story

[Ken Knierim]

Ron,

Average ground temp in central Arizona is over 80 degrees and higher
than that right now. Outside temp is better than 115 degrees as I type
this. Pumps are calibrated at 60 degrees according to federal
standards but the ground doesn't care; no temp regulation exists.

Solids, liquids and gases usually expand when heated, right? Do you
THINK there might be a LITTLE expansion in the fuel with that kind of
heat?  Do you know the coefficient of expansion for petrochemicals or
more specifically, gasoline? Some quick research shows it's close to
4X that of mercury:

With all due respect, there IS a difference due to temperature. Now
whether you'll notice it with a vehicle is another story, but claiming
it doesn't exist is like saying the earth is flat. You might not be
able to see it (or electrons, for that matter) but claiming it's bull
isn't very open-minded.
