Since the air/fuel ratio is controled by the computer, the only way to get better mileage is from more timing. This will only occur if an additive can supress knock and detonation enough for the knock sensor not see any knock. When this happens the computer will allow more advance.

All the additives that do this that I'm aware of are highly carcinogenic.
