At these orbital heights, there is no atmosphere for drag effects, so adding energy to move to a slightly higher orbit, outside of true geosync altitude, is a permanent change. Low Earth orbits do have atmospheric drag issues, and those items need to have fuel to replace lost velocity and restore the correct orbit. The ISS page has a neat table of orbital height over time where you can see the burns to 'jack it back up'.
