NOT bodiesel. Blending WVO and Diesel. Has anyone ever tried it in their 7.3?

I drive a MB 300SD turbodiesel now. I have had great success blending the two. The car even seems to run better and quieter. I will be in the market for another winter car in the next year or two and I was considering an Excursion with a Diesel. I have heard the horror stories about the 6.0L so I was looking into the 7.3. Has anyone ever blended WVO/Diesel with this motor? What was the outcome? NOT what you heard either, just personal experience.
