View Full Version : B100??

10-19-2005, 02:12 PM
I just found out that there is a place fairly close to me that sells B100. Does anyone here run B100? I'm really just starting to research the whole biodiesel thing and the thought of running B100 (which I assume is 100% soybean oil) kind of scares me. I also have no clue what it costs.

A local supplier sells B100 for ~$3.00 gallon.
I'm thinking of getting some and blending my own B20.
I've heard that B100 is tough on rubber seals and hoses in the fuel injection system.

Aside from the seals and hoses, do you have to have any special equipment to run B100??

If I were to blend this myself, could I just buy some B100 and then pour X amount into my tank when I fill up with diesel or does it have to be blended and THEN pumped into the tank??

Your common rail's fuel filter will plug rapidly with B100.
Cummins recommends B5 maximum but you can most likely get away with B50
Even though I fully support BD and work in the industry B20 is the highest rate I use.
Mileage and power starts dropping for me then.
Until the price of BD comes down a lot more it just doesn't pencil out.

When you figure that less than 20% of our oil imports come from the Arabs just using B20 will cut them out of the picture.

Thanks Infidel. That's what I needed to know.

My mixture is about B50 right now. Truck runs good and smells good! Some say you can run B100 in the HPCR without issues, other than a little loss of power and fuel economy. B20 seems to be the compromise.

You all shouldn't have any trouble with rubber corrosion on your new trucks... At least not in the fuel lines, if they're stock. Cummins uses teflon lines which aren't affected by biodiesel. Look out for that gelling, though. My buddy has converted his isuzu NPR to run on straight vegetable oil, and that seems like a pretty sweet, if involved, deal.
