Love my 06 5.4
We bot a new 06 eddie bauer w/ tow pkg. Now with 115k n still runs like new and town n country drivin get 15.5 to 17.1+ mpg. No plug or problem of any type yet. I replaced all plug wires at 105k as #1 was breakin downunder load. We regularly tow a 6k lb trlr and go over 11,500 ft mountain passes at 55-65 mph. Frwy speeds of 75-85 are common.
I use Pennzoil fuel injector cleaner every 5k mi and have FRANTZ filters on my engine and tranny and have no partical or discolor on filier.

In my 08, sometimes I find myself expecting more power than there actually is. Im just about to break the 32xxx mile mark and I'm pretty sure I have a misfire. I get some nasty vibrations in the pedal when reaching the point in the RPMs where the granny is close to shifting and it takes me nearly 3k RPM in town to just keep up with traffic.
