In fact 87 octane actually had more BTU value than the higher octanes.........higher octane just means that there more anti-knock chemicals in it to cause a slower combustion burn, to avoid pre-ignition(knock/ping).

it depends on what you consider negligible. this was brought up on another forum i frequent and someone dyno'ed their car with 89 octane and again with 93 and posted the results:
and that's compared to 89 octane, it's probably even more of a loss running 87. some people spend good money modifying a car to gain 12 hp and 13 ft-lbs. of tq, especially at the wheels. It seems a shame to throw that power away to save a few cents per gallon.
