All,
Just wanted to give a quick update on my experiences so far using "BioWillie" bio-diesel. I think it's important that we keep sharing our experiences on this subject, good and bad, since many of us (in the U.S.) will see this alternative fuel become more common.
I filled up with B20 and have driven a few hundred miles now. As others have experienced, my engine seems to be a little quieter than it was. I have not noticed any power loss, but I'm not sure that I would notice it since I drive like an old man. :-)
#2 BioWillie was 2.599 per gallon. Regular #2 diesel was 2.799. (North Dallas, Texas).
I have noticed a "sharper" odor from the exhaust. I don't know how else to explain the smell. The source of the oil used to make biodiesel will alter the odor. I have read that "BioWillie" is made from soy bean oil.
No complaints thus far.
