Ok so here is what I know.

I have an 86 6.9 diesel that I run black diesel ( filtered motor oil) in and in the summer I run it strait and in the winter I cut it with regular petrol. I have had no problems and have been doing it with some friends for about a year now. I know 12v cummins can and 6.0 powerstrokes will and my buddies duramax love it. Now an other friend who has a 95 powerstroke wants to do it to ( he travels alot for work hauling carpet) I've done some research and it seems that this generation of powerstroke would be a good motor to run it because of the huei (or however you spell it) fuel delivery system. But has anyone done it reliably and not have problems? I so did you dilute it with diesel or petrol? Thanks in advance gents.


I also realize that this fuel takes it's toll in injection pumps and injectors when done wrong so in your replies assume I know what I'm doing. I filter to 1/2 micron with a centrifuge.
