Sorry Oppy, I just now went back and found the post to check on how the trip went. An article was published by a University on the comparing cetane ratings for blends & pure biodiesel, #1 diesel, #2 diesel, kerosene, ..... Of course I can't find it when I need this information! I don't remember if it was in my Home Power mags or the Internet sites.

Your info is good news though. I must have mis-read the data as I don't notice a diff. I mainly do short drives under a 100 miles a day; some stop & go. Perhaps in was BTUs or power factors? I was actually looking for schematics & articles on wiring solar panels since this is my main interest in alt energy.

Thanks for info on my error Oppy. Let me know if you come accross any numbers on this or BTU comparisons. Thinking in the future of biodiesel furnace.
