I hated it also when they removed the sulphur from fuel, removing cylinder heads to do valve jobs was easy money, replacing turbo`s when chunks of sulphur broke loose, easy money.
If you see a train, with bright yellow pellets in the hoppers that is the sulphur.
Putting in additives in the Fuel, they have been around for years, they always find a reason you should use them.
I worked on engines Class Eights all my life and never once had a customer bring any equipment in and tell us they used an aditive not once.
There is a lubrication study out there thedieselgarage.com site 2% bio is the best there is. Better than every aditive, many additives were worse that just diesel, they are still available and advertised.
Please google the diesel lubricity survey, and save your money.
Just a thought!
