ZfirstVette

I prefer to run 93 octane in my 2010, but 93 isn't available close by. There is however, a station nearby that carries 100 octane. I planned on mixing 91 and 100 to achieve 93 (using an octane calculator) which would also be cheaper than the 93. My question is in the mixing and the fact the vette has two connected fuel tanks, something I did not know. Do you think the two fuels would get mixed good enough?

They would be mixed fine within the 2 tanks I'm sure. But there's so many variables. You're better off just tuning to 91. Atleast my opinion. Or to 100.

Are you sure the 100 octane is not AV gas? That would be bad in the ZR1 as AV gas has lead in it. I would burn the 91. I also believe with a blower 100 would be hard to light at high RPMs.
