the base gasoline used by most retailers in an area all comes from the same terminal - but which and how much ethanol, detergents, etc. are put in can vary. Most likely, you'd be better served by staying with a high-voluime retailer like Kroger and throwing in some off-the-shelf Techron or Seafoam every 6 months to 2 years or so.
'most' of our gas actually comes from Kroger or Costco too. The other day my wife got 60 cents per gal off with her kroger card! She drives an 03 and we have always used premium as suggested by the manual. I doubt you'd see even a remote improvement by using a higher grade gas than recommended in your manual. That would be a waste of money.
