I can almost always get above 18.5mpg out of every tank. I have done the following my self and it really isn't that expensive, especially if you get like an extra 1-2mpg out of it.
Plugs, wires, rotor, cap, MAF cleaner, PCV valve, fuel filter, stock CAI mod with a K&N, and a bottle of BG44. I use BG44 twice a year. i tend to drive kinda heavy too and im up here at altitude. I feel, for how I drive, and what the xterra is rated at getting i get great gas milage.
