Out here in phx az the highest octane at a gas station I can find is 91. But one of the stores down the road sell 100 unleaded Sunoco out of the pump. I want to run the 93 map on the cobb just to see what it's about. How much of 100 and how much of 91 would I need to mix to be roughly in ball park of 93 94.

I'd be asking whats in that 100 unleaded fuel, most likely MTBE, DIPE, TBA or some other oxygenate. It's not easy to make high octane w/o lead!
