Maths. I'm getting 32 MPG. 93 Octane is currently $3.30. Low Octane s $3.00.

If I go 320 miles, I use 10 gallons. That would cost me $30 if I were in a different car (still getting 32 MPG) and could buy Low Octane. $30 will only buy me 9.091 gallons of 93 Octane though, for the FR-S. With 9.091 gallons I can only go 290.91 miles in the FR-S.

So having to buy 93, at current prices and fuel consumption, is like dropping from 32 MPG to 29.1 MPG for me. My Si got in the 23 MPG to 26 MPG range for about 95% of the 130 or so fillups I did in it.

Of course, the actual effect will be negligible given I will probably put 5000 miles/year on the car. 156 gallons/year x 30 cents = $47/year = $3.90/month = 90 cents a week.
