Keith, I'm new to this so forgive some 'dumb' questions!
When you use the term bio-diesel, are you referring to 100% bio or a mix??
I've looked at the standard and I would assume its for 100% bio, right. When we get into a blend, I would assume that since the bio contains no sulfur, that the total sulfur content comes from the petro. I wonder how a blend would change the total sulfur content? Is it simple math, since we have a 20% dilution per gallon??
I am in many discussions and the term b20 is used to indicate a 20/80 mix of bio/petro. My main interest is 'at the pump' what do we deleiver?? b20/b100 or n/n??
Tx, Frank

Hi Frank
Yes.
Biodiesel is 11% oxygen by weight and contains no sulfur.

Also, you can use ULSD in any diesel engine if you add a little
biodiesel for the lubrication. "Adding one percent biodie! sel improves
the lubricity up to 65 percent" (executive director of the NBB Joe
Jobe). See Biodiesel Development Corporation -- Biodiesel: Cost

The French add 2%-5% - mostly 5% - for this reason.
