My brother and me have been using blends for years too. We started with the "Diesel Secret" but that didn't last long. We run 40% diesel, 5% RUG, and 55% WVO. (approximate). Works excellent in a 7.3 Ford too, over 200k miles of experience with that truck on the blend. I now have a single tank kit from Mercedes Source on my 350SDL but I run some D2 in it also. Diesel Purge once a year.
