Diesel Fuel Lubricity --- Situation back in mid 2000s.
Information need updating.
At the time ULSD was phased in, the question arose as to how to add lubricity additives to fuel in USA.
Pipeline makers objected to the lubricity additives as it may contaminate their other products (many different products are sent through one pipeline).
Some pipeline makers allowed refineries to have pre-mixed (lubricity additive added) diesel through.
Others said no --- and lubricity additive was done at the terminal just before the diesel is shipped on the truck.
This is very similar to how gasoline additives are added to "branded" fuel from a common batch.
Therefore, if you got fuel directly from the refinery, you probably have a high certainty that the refinery did its job.
If you got fuel from a location where additive is added at the terminal, it is a dependent on the operator.
Could diesel without additives be sold (especially at "off brand" stations).. the question is yes.
How is lubricity enforced? At the state level.
Here is the EPA slides on the issue dating from 2004.
