Top Tier gasoline around me easily runs $0.15-$0.20 higher than non-Top Tier fuel. At that difference, it's cheaper for me to throw a bottle of Techron in the tank every 5,000 miles, which has the same effect. That's good price for it too; I'll have to grab a few bottles.

That is simply not true for 99% of the country,

It is absolutely true around me, when you factor in that nearly all of the top tier gas stations near me charge *at least* $0.05/gal to use a credit card (including ATM-debit), and I can get non-top tier fuel (USA Gasoline, aka Tesoro, or Costco) for a $0.05 to $0.10/gal cheaper (91 octane) and not get a CC surcharge.

It also matters that you're in one of the least-expensive fuel markets in the country and I'm in one of the most expensive.
