You mention Low Sulfur diesel which is 500ppm sulfur and is not available for sale for highway use.
All Diesel fuel available for on road use is ULSD. It will have this label on the pump.
Bio-diesel is blended with ULSD (B-5 B-20 etc) unless it is pure bio-diesel, (B-100.) If more than 5% bio, it should
also have one of these labels. (does not seem to be enforced??)
