Is one preferred over the other? If so, why?

I'm thinking of adding another Excursion to my stable, specifically a PSD but want to run bio-diesel (of which variety I'm still unsure). Diesel is still .50 more than gas here so the numbers really have to work out.

 

I know my 7.3 runs great on B99. I cant speak for the 6.0.

 

I have been running B20 in my 7.3 for about 6 weeks (ish) now, and have not had a single problem. I'll probably change the fuel filter this weekend just to be safe.


FWIW, B20 is about $ .10 cheaper than #2 diesel around here.

 

Ive been running B50 for the last 3 tanks in my 6.0 and my last tank is basically B75.............Works great!

 

We just turned 100,000 miles, all on B100 in our 2001 7.3 F450.

 

Maui, ive been there last year.

 

I have run many combinations of bio and dino. Stated mixing myself at the pump with B100 and dino. B20 was my first mix and now I am up to approximately a mix giving me B75 and up B90 bepending on what my current tank level is and what prices are at the time. I use it in both the 6.0 and 7.3 and it runs great. Mileage about the same. Power may be just a little less. Amerigreen (Soybean) Biodiesel has been great so far. Been using it for about 6 months, only in the summer months with the higher concentrations. When winter hits PA I only run a B5 bio/dino blend and there are no gelling issues. Seems to run much quieter too. Hope this helps.

 

The manual on my 05 psd 6.0 says not to use more than 5% biodiesel, I asked the diesel tech's at the ford dealership and they said not to run bio in it. I am intersted in what you guy say about it. I origanally bought the thing to run DSE, but after reading here about it I have decided not to do it, but I'm now considering making biodiesel
