Interesting thought...you may not notice a difference but your engine will thank you. those horror stories are engines that are already beyond hope and the flush has moved some of the metallic debris into bearing shells etc.
the flush will help remove any sludge anything left will be suspended in the new oil and trapped by the oil filter.
If the new oil stays golden then all is good, if it goes black quickly then I would do yet another oil change at about 2-3000 miles.
with an internally cleaned engine there should be less friction and a possible increase in MPG.
I just had another thought, if the sludge is that bad it might be worth during a service dropping the sump pan and giving that a good clean as well, the oil pump pick up is probably sat in thick sludge, I've seen this on classic cars with low oil pressure. The flush should loosen most of this, I wonder if a camera would fit into the sump plug for a look...…..
I think I will go ahead with the flush. Is there any benefit to doing it gradually? Say 1/3 of a bottle of flush over 3 oil changes for the full bottle?
Is it fairly simple to drop the sump?
Edit - the oil I changed 600 miles ago is still golden-ish... It's definitely not looking brand new, but it is still golden somewhat
