The first time I pumped 93 Octane into my tank I noticed the MPG numbers in the dash made a big change after driving my FGT for a couple of minutes. I assumed this was because the ECU determined the octane change.
Don't know if the ECU does this, like the Elantra N, but I got a kick out of the MPG changes.
