I miss 93 octane. It definitely made a performance difference. In the 350Z (last car to try 93 octane), throttle response was awesome and it was easy to spin out of 2nd while making a turn. When the tank gets close to empty it starts feeling a tad weak until I fill it up again.
I wonder what it feels like with the 370Z.
Anyhow, most of the gas stations here contain 10% Ethanol.
