Race fuel for FI

What kind of race fuel have u guys used with ur setups? Built motor ysi and aux low side here.I have heard good things about ms109, sunoco 260 gt+. I am trying to stay unleaded so I dont have to be changing my o2 sensors. I have also read about gulf mach 116 which is the highest octane unleaded fuel out there. What would u guys prefer? Sunoco 260gt+ is probably the cheapest and same octane rating as ms109.

I ran c16 for racing events and MS109 when I just wanted to go around town. Now I run port injection and full E85.

ms109 is the most popular I have seen out there. But mach 116 has alot more octane then 109. Was leaning more towards mach 116
