I'm telling yah......the performance difference between 87 octane and 90+ is very negligible.
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).
