fuel additives
Curious as to how many ( IF ANY ) are adding fuel additives to their newer age diesel 6.7's ?? I used to use Power Service- Silver in the summer and the white in colder temps back when I had my ol...

Your fuel may meet the standard, you don't know. I have yet to see any diesel pumps that show the cetane rating anywhere.
Using additives because your fuel "may" not meet standards? Nuts!
Bigfoot "may" exist but probably not.
ShinerBock-From your own cut and paste article.
"Cummins® engines are designed, developed, rated, and built to operate on commercially
available diesel fuel as listed in Table 1: Cummins Inc. Required Diesel Fuel Specifications;
therefore, it is not our policy to recommend fuel additives.therefore, it is not our policy to recommend fuel additives.
In certain situations, when available fuels are of poor quality or problems exist which are
peculiar to certain operations, additives can be used. However, Cummins Inc. recommends
consultation with the fuel supplier or Cummins Inc. Service Engineering Department prior to
the use of fuel additives.
Actually, most states publish their random fuel sampling data and provide it free. Below is an example report from 2014 for the Texas Commission on Environmental Quality.
2014 Summer Fuel field Study
As you can see in the report, there are several samples and regions below Texas's 48 cetane and other requirements. I have seen the same kind of reports from others states when I worked at Cummins showing samples that were even below the federal 40 cetane and other requirements. So yes, the data is there if you look and there are many places under Cummins' minimum requirements. Therefore additives may be needed to bring the fuel up to spec as stated by Cummins.
Also, you should read the whole service bulletin (and paragraph you just quoted) instead of cherry-picking data for your own predetermined beliefs. Just because it is not their general policy not to recommend additives without consulting a fuel supplier or a Cummins engineer first(which is lawyer-speak to cover themselves), does not mean they don't recommend them in certain situations as stated in the additives section of that service bulletin. Plus this recommendation changed in 2017 with..... LINK
Again, I KNOW they work because I was a part of the fuel/additive testing when I worked for Cummins. What diesel engine manufacturer and technical research did you do to come up with your theory that they don't?
