I've gone from about 240ish-250ish miles per tank to around 270. That's not too bad of an increase. I also used a bottle of Berrrymans B-12 Chemtool in the tank simply because online reviews were pretty good and it was like $3 a bottle. I don't think the SeaFoam spray was really all that necessary, more of a "what the hell, I'll use this too", but the other two helped out.
I have yet to do plugs, but I'll do those next paycheck.
It might be worth mentioning that aside from the additives, I also did the pedal dance to reset the ECU. That may have helped clear all the settings I'm assuming.

Not sure how good simply unhooking the battery is. Had a MAF code that would come and go (would reset it using hand scanner) and the battery reset didn't help. Did the pedal dance and code went away and has yet to come back after about 2k miles.
