The problem with using lower octanes is engine knock, a retune or engine map could account for it but it's not recommended with forced induction. The higher the octane the more it resists detonation. Basically without tuning for the lower octane mpgs would be worse, or cause more damage in the long run even with a tune/map. It is debatable, but dozen have burnt out cylinders from lower octane or the wrong a/f ratio in these and other high performance engines.
