ULSD vs Regular Diesel / Have You Noticed?
This is a question and not a statement... Almost all of the lube oil contamination can be traced back to soot. And in theory more soot is formed when sulfur is present in the fuel. Of course incomp...

Is it an issue of sulfur laden soot damaging the particulate filter or regeneration system?
Always thought it was more for NOx reduction.
Wikipedia and it's footnotes has some info: https://en.wikipedia.org/wiki/Ultra-low-sulfur_diesel

EPA, the California Air Resources Board, engine manufacturers and others have completed tests and demonstration programs showing that using the advanced emissions control devices enabled by the use of ULSD fuel reduces emissions of hydrocarbons and oxides of nitrogen (precursors of ozone), as well as particulate matter to near-zero levels.
Europe started ULSD in 1999, Canada and US by 2006.
EDIT: and by the way, in terms of soot, the exhaust tip on my Cummins is perfectly clean after 35K kms, whereas the exhaust tip on my previous F150 Ecoboost was quickly sooted. Apparently DI turbo gasoline engines are a major source of fine particulates.
