I've got a 2005 ZX3, Duratec 2.0L ATX, just over 6,000 miles on it. The sales guy stated the ridiculous number of 20,000 miles before the engine would be broken in enough to come close to the EPA rating of 34mpg that was on my sticker. (I'm getting between 28-29mpg, and spend most of my time commuting (highway) 100 miles per day). I have the poor-man's CAI so far; i.e. the cone filter on the end of the MAF tube. I've been watching my mileage pretty closely since I got the car 2 months ago, so my 28-29mpg is pretty solid. (The cai thing didn't change my mileage at all, yet.)
