More than one study has shown that using "regular" gas gives not significantly different results than any other grade. Cars are now computerized and they make adjustment for the grade of gas used.
Admittedly, using higher grades of gas speeds the flow of $ from your pocket.

That is mostly correct. Many modern cars do retard ignition timing and work adequately with regular gas. My experience is that turbo-charged Volvos with modern engines ping with regular fuel.

When I first got my '01 S-40 I kept records of my gas milage using different grades of gas. While it ran just fine with regular and middle grade gas, the gas mileage went down, compared to the recomended premium. After figuring out the relative costs per mile, it turned out that running premium was only costing me 2 or 3 cents more per gallon.
