My opinion, though mostly all we've got is opinions on it and they vary widely, is that it's best to run through all of the load range, from full positive to full negative, in as varying an rpm range as possible. So when I drive on the hilly highways out here, I might go up a hill floored in 6th (it'd reach 4k rpm too soon in 5th) then get all the way out of the gas to give it maximum negative load. Let any metal particals get vacuumed out the exhaust.
