haha ok [(91x6)+(116x1)]/7= 94.5

formula is [(pump gas x gallons of pump gas) + (race gas x gallons of race gas)] / total gallons of fuel

Are you running a boost controller? If not, there really isn't any point in spending the money on race gas unless you can only get 91 **** at the pump. The ECU won't crank up the boost for you so you'll just burn more money instead of rubber.

If you only mix in a couple of gallons of race gas do you guys think it will still burn up the 02 sensors?

and then too...it's just a couple gallons you would be using.

Sunoco makes 104 unleaded if you have the ability to get it. You can call them up (http://www.racegas.com/fuelspecs/default.asp) and just ask where the nearest dealer is. I found out mine is right down the damn street!
