octane booster usually also includes fuel stabilizer, injector cleaners, and other additives not found in regular fuel. the octane boost would be probably very close to the 4 point difference from regular unleaded to premium.
IIRC octane booster works by tenths of points, so if it says its raises it by 10 points its actually only raising it from say 87octane to 88 octane. Dont know if its true or not, but I do remember reading/hearing that awhile back.
