i probably wasted my money, but during the 1200 mile break-in period I filled up with Sunoco GT 100 octane gas from my local 76 station (woodside, redwood city).

Occasionally I go back to mix 100/91 to get ~95 octane, but mostly just fill up at the whatever gas station is near, Shell, Chevron, 76, and Costco gas.
