Well, I have to admit that I thought you folks were making a mountain out of a molehill with this biodiesel question. So, I sent an email to Pilot/Flying J first to see if they were offering both biodiesel AND regular diesel. According to them, they are not. If they are selling biodiesel, that is all they are selling.
Next I sent an email off to Cummins. They were not at all encouraging. First they said that if you burn biodiesel, you should cut your fuel filter change intervals by 50%. In other words, if it was 10,000 miles, it is now 5,000 miles etc. They also warned about damage to gaskets and seals and didn't offer any reasonable solution to that problem.
SO---- I share your concern about the bio-diesel. I do not understand why the truckers are not screaming up a storm over this. It seems to me it is a legitimate concern and I know that now I am concerned!!!!!

I apologize to all of you whom I thought were making mountains out of mole hills. And I am surprised this isn't located in the "Class A motorhome" forum.
