[AT] OT: Gas story

Thu Jul 5 11:55:16 PDT 2007

     I've found this debate to be fairly interesting
as well. My thoughts as far as hot fuel and my
experiences with the Flying J is that their fuel
doesn't sit long enough too cool down. I don't
exaggerate when I say there's at least one tanker
delivering every hour and the pumps constantly have
customers.
       There was a question some posts back about how
accurate some peoples fuel mileage may be. I can say
mine is only as accurate as the fuel pump and my
odometer. I do check it every time i get fuel and do
go as far as marking where and what pump I use along
with whether its low sulfur or ultra low sulfur I put
in. With ultra low sulfur I find a decrease in fuel
mileage  as well. I don't do all this with my pic-up
but my Mack is what I make a living with and so every
dollar I put into it I want to see where it goes and
what I can do to save $$$$
