Actually, there are over a hundred oil refineries in the USA with many being
in the southern US.  Unfortunately, all of them are quite old.

Be careful to consider geographical influences. There are no Arco stations
near 
me, in Detroit, Michigan. There are also no Chevron stations. Personally, I 
use�almost exclusively, the gas from my local Sam's Club in all four of my 
vehicles. I have never had a fuel related issue from them. Their source, 
directly, is unknown to me, but again, there is only one refinery, in the 
southern U.S., that actually creates the eight-carbon based fuel we all use.
It 
is all about the additives, and how many brokers it passes thru, before it
ends 
up in your tank.�

The difference in per-gallon price, credit vs. cash, though, does still show
up 
around here. Some have the outrageous difference of a dime per gallon
difference 
(!), but most are a nickel, or so. The individual station seems to be where
it 
comes up, rather than a particular brand.

Subject: Gas Brand Preferences?

I see, in several responses to my posting about Arco's 35 cent surcharge on
gas purchases, that virtually everyone expresses a preference for Chevron
gasoline.� That includes me.� But is there any objective data to support a
superiority of Chevron gas?� Curious minds wonder.
