I use 93 in my busa [lack of knock sensor,hot summer days] and my S-10 pickup that I drive to work on less than perfect days. Without a doubt the gas milage is higher with 93 than 87 EVERY tank that my wife and I tested. By the time the first half tank in either vehicle is gone we can notice the difference in fuel milage, and with the S-10 performance also. Dennis see Sonic Boom's post above yours.
