Anybody running biodiesel in a 6.7? Are you making it yourself? What equipment are you using?

 

I've tried 5%, 10%, 20%, then 80% with no problems. I'm unable to use it on a regular basis, as the nearest station that sells it, is almost 200 miles away.
i did get a egr code while in AZ. i didn't check the pumps. i was fueling up with the higher sulfur diesel, (3 times in a row) oops. i run the tank below 1/4 and fueled with low sulfur next two tanks and the code went away.
10k miles 1 oil change and no problems. towing 10+k went from 8 mpg to 12 mpg on trip from Oregon to AZ. on the way home averaged 10 mpg but was passing rigs through the Siskiyou Mountains. empty i get 17-22 depending on right foot. 08 3500 mega cab 2x4 auto.
