That'* motor flush. It basically thins the oil to a water consistency and tries to dissolve all the buildup at once, after which you hope that it all drains out so that its residue doesn't thin the fresh oil you put in.
Like the others said: Skip the miracle additives crap and just do a couple of short-term oil and filter changes -- say, no more than 500 miles per change. After you've done that a couple of times, you _will_ see an improvement, and you can maybe go for 1000-2000 miles before your third oil change.
Remember that oil is _supposed_ to suspend dirt until the filter can get the bigger stuff out, and the oil keeps the rest of it (the really microscopic stuff) in suspension until you change it. So if the oil turns black, it'* doing its job, since it is finding dirt and picking it up. Things _will_ get better after you've done a couple of short-term changes. Don't worry about having to do anything above and beyond that.
