"This is not to say that they were not on the road to coking up. Based on your filter description of black specs in the pleats, this may be an indicator that some ring type deposits were cleaned out. I would say without a doubt that the ring packs are healthy"
Auto-Rx always cleans out contaminants in any engine.
