Where do you buy gas?

[Uncle Bob]

Actually the BP refinery (used to be ARCO) here in our 4th corner of the Pacific Northwest uses almost exclusively North Slope crude. The balance is made up from Alberta. The other 3 refineries (Shell...used to be Texaco, Conoco Phillips...originally Mobil and the Tesoro...used to be Shell!) all have similar purchase strategies. Conoco Phillips is the oldest and is most able to take advantage of Far East crude.

Me? I have used ARCO (BP) fuel 91 and find no difference from the other $.10/gal more 91 grades.

I do stick to a high volume station as well. Consider that as gas prices have increased, less higher priced fuel is sold, so the likelihood of purchasing "old gas" is even greater!
