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.
