duramax 3.0 fuel additive

I've never noticed it at the pump, but I haven't looked either (spec says they need to display at the pump)

I just read through the Top Tier spec https://www.toptiergas.com/diesel-licensed-brands/; the only spec's it calls out are: ASTM D975 or ASTM D7467 which are the standard specs for diesel types and biodiesel amounts, water monitoring, 10 micron filtering.


Reading the above,
Someone explain to me how an additive would address any Top Tier spec other then water intrusion? Or am I missing something? IE, I'm not seeing a spec around lubricity or cetane for example.

On gasoline it's the additive package of detergents that make it Top Tier.

I don't see anything about an additive package for diesel. Basically what makes top tier diesel is the filter micron rating and adherence to this "housekeeping" document for storage and dispensing. https://toptiergas.com/documents/10/CRC_672.pdf

Only thing I use is the additive for fuel in freezing temps, so far so good
