and it all depends on the ignition timing. the more advanced it gets the higher octane it requires. for some reason i noticed that manufacurers reccomend the 86 and higer for cr of 8.5:1 and 93 octane for 9.5:1 and higher. also the higher the octane gets the hotter the temps inside the cylinders will be

doubtful since my civic came with 9.2:1 compression ratio and is supposed to be run with 87, then the newer civics have like 9.5:1 and also run 87.

octane doesnt make anything hotter either.
