Diesel fuel filters work down to 6micron, but I can't see if an additive oil is fully dissolved in the diesel fuel it would fail to go through. Even very big molecules are nothing at all compared to 6micron. The only time there was a filter problem emerged with PTFE in suspension added to engine oil in the old days. The stuff just clogged the engine oil filter. I remember it was called "Slick-50" if my memory serves me right.

I use BG244 and Archoil 6200 in mine! The filter i have on there now is a UFI one.

 

Slick50 (PTFE ) was made my Dupont and was never made to be used in the Automotive industry! Slick 50 had millions of dollars law suits againts them because of damage caused due to clogged up oil ways resulting in engine fail. Ford used it in there Capir Laser gearbox back in the 80's. I used the stuff in my 1976 Escort that ruined my engine! But back then! There wasn't the info out there. Thanks Slick 50

 

Low ash mineral 2 stroke is an oil just like diesel is a heavy oil! 2T burns cleaner than 35sec diesel and dispersal into the fuel is complete b4 it gets to the combustion stage. It's not recommended to use the full synthetic 2T oil. Semi synthetic could be used! But the cheap mineral one works best.
