I've been using stanadyne from the Cummins shop when I can get there and get it. Last night I added 23 gallons of B20 biodiesel, that should help the lubricity of the ulsd. Schaeffers' has an additive called soyshield I believe that I am trying to get........but try and find someplace that has Schaeffer products on the shelf Got me thinking I should try and become a vendor so I can have some product on hand I can buy from myself to use in my truck!!
