I've tried both and I see no diff in economy, lower octane is actually supposed to have more BTU in it, but of course, retarded ignition and richer mixtures to combat knock can offset that. I myself don't notice appreciable power loss, on a dyno, where you have to deal with heat soak etc, sure, premium will reduce power, but how often do are you at full boost for more then a few seconds?
