How's that for spin doctoring a for-crap situation?

For an extra two dollars (based on 20 gallons) you can increase your timing just that little bit more for more power, and better fuel efficiency. Believe it or not, you will see better returns on midgrade for the dollar vs reg, but maybe not premium unless you tune for it.
EXACTLY. Looking at those big signs at the gas station with the gas prices on it, I don't think much people do the math. All they see is regular is cheaper by +/- 20-cents, or so...than super. Those are the ones that don't notice that their engine is pinging, either.

Sounds like my wife, she'll drive clear across the city to gas her PRIUS at Costco to save a dime a gallon.
