I have a 04 disco 2, 4.6. I can tell that is has some valves sticking. Can anyone suggest an oil or fuel additive to put in it to help free them up?

Italian tune-up. Do you have about a 10 mile stretch of freeway nearby? You'll have to exceed the speed limit, somewhat.
What brand and grade of oil do you use?
What brand of gas do you run? What octane level?
Run a couple tanks of Chevron or Texaco 92 octane AND a bottle of Techron, then report back.
