I'm looking into using soybean oil for a fuel additive for my 04 6.0L. I'm thinking of using it for viscity reasons. I'm sure I would blend it w/ DK. My reason in still using DK is for the water treament and cleaning if soybean oil turns out not to be much for cleaning.
Why soybean oil? Cause it is readly avaible to me right now and wont cost me anything. I would be adding this oil to regular #2 diesel. I have no problems using biodiesel just nobody sells it near me.
