Dean,
I have not used the ***** Biodiesel Stations as there are none in Canada; however I have use a local supplier of BioDiesel going on a year now.
I started out using B5 then B20 and more recently B40 Blends. (i.e. 40% Biodiesel and 60% regular No. 2 Diesel)
The IDI diesel in my experience run really well on it and the Stanadyne Injection Pumps seem to work well with Biodiesel.
The only mistake I make this winter was I should have dropped my biodiesel ratio from B40 back to B20 as the B40 tends to start to solidfy between 20 and 30 F and we had a few cold nights were the temps dropped down to 20 F. Ended up freezing my Injection Pump and needing a new pump. Oh well live and learn I say.
Overall the biodiesel will let your 7.3l run:
1, quieter due to the higher Cetane value of the BioDiesel
2, less smoke because Biodiesel burns hotter than regular diesel giving you a more complete combustion.
3, Milage with B5 and B20 is about the same as regular diesel; you may get a small milage drop with the higher blends like B40. This is because Biodiesel does have slightly less Btu/gallon than regular diesel and with the higher blends the gains you make due to better combustion will eventually catch up with you in the lower Btu/gallon resulting in a slighly lower milage.
Recently ran my 91 thru the local Annual Aircare inspection on B40. The truck passed better with Opacity down almost 3:1 (3.5 vs. 9 ppm) from what the truck had on the last years test. Hotter combustion = Less smoke even with the more intense testing that is being done now.
Overall I would say old Willie Nelson is on to something that not only helps the farmers, help a little on reducing dependency on foreign oil and also is better for the environment. You can't go wrong with that.

Are you already running bio and looking for another source or wondering if it is ok to run? I buy biodiesel from a station here in California that charges 3.39/gallon. It's from a flaxseed base. No troubles except an aftermarket fuel line that I replaced when I put in a Racor filter started sweating through. What year is your truck? Earlier years might have a problem with the fuel line and you may need to switch to all viton hoses. Check the alternative fuel section of this forum and post your question there.
