I am sure the articles say a lot of things, just as I am equally sure not one of them has come out and said "this product is bad" for your fuel system and actually named it. What needs to be portrayed is a valid comparison of something that makes sense, like molecule size for example, of additives that are being represented as potentially "bad". Better yet, maybe a comparison of the MSDS of diesel and the additives to see what is actually IN them?
A better question for the pundits is how are these additives that are designed for lubrication so much worse than the asphaltenes that cook out of the ULSD in the CR systems? Since the CR's ran just fine on LSD fuel it is hard to buy into this hype when it is fact that long chain molecules in LSD were magnitudes larger than ULSD. It makes about as much sense as stating that sulphur in the fuel added lubrication, just not even on the right track.
Now it seems that the real determination of an additive is it has nicer properties. What the devil does THAT mean? I cannot find that measure on any labeling or MSDS sheet available for any product. What I do find is that amazingly all the additives are pretty much the same constitution with the obligatory secret component in varying amounts usually les the 20%, 2 stroke oil included if we really want to stay on point.
Things like this "The tolerances on these injectors are 25 millionths of an inch clearance" get propagated as something with actual value when they are patently false. It doesn't take much to figure just how wrong that is. Best information we have at this time says 2-3 um is the CR injector clearances, that would be something like 7 one hundred thousandths to 1 ten thousandths of an inch. On the scale of size that is magnitudes larger than 25 millionths of an inch. BTW, the bulk of this information is coming directly form Bosch engineers not the customer relations management division of any manufacturer.
Sorry, put comparing magic markers to 2 stroke oil just doesn't make an impression. Definitely one for the circular file.
