I have yet to see empirical evidence showing its any good.
A heavy-duty diesel engine can do 1,000,000+ miles with proper maintenance, and commonly available HDEOs, before getting an overhaul. It's not unusual for most of the components to be within new parts specifications. This is without using any of the "wonder-products" that are hyped, like Lucas and other well known brands.
Personally, I give these things a pass. Even if they had a marginal effect, the costs to use them over such a distance would be exorbitant. Besides, if the used parts are already within spec and reusable, what would the benefit really be?
