From reading this Quote...."Older vehicles and equipment will run on ultra low sulfur diesel and will experience a small reduction in particulate matter.".... and the other links, the main reduction is in the particulate trap and not so much that the ULSD will produce much less soot.Quote...."...
This is the Response that I got from Power Service
Dear Machinistika:
Thanks for bringing this to our attention.
No, our current Diesel Kleen + Cetane Boost or Diesel Fuel Supplement
would NOT make lubricity worse in any test or fuel.
Attached are some HFRR data (D6079 High Frequency...
Thanks 1040Werckerman. If this is legit, the only thing I can figure is that DK uses something so dry (like kerosene) that it can't lubricate itself let alone the diesel. One must note that the diesel was "UN-TREATED" so I would assume ULSD. Since theULSD we get from the pump is treated at the...
I found this link(http://www.delphidiesel.com/DATA/DDSU203.pdf), and it shows that Diesel Kleen (Power Service) actually decreases the lubricity of un-treated diesel fuel. Mabey that is where the metals are coming from in alot of the UOA. If this is an accurate rating ,it is bad news for me...
