| Post subject: | running b99 |
I have a local commercial bio-fuel plant selling b99 , is there anything I have to do to my CRD to run it? The price is significantly below the current diesel prices in the area. Thank you. |

Usually Bio is more expensive, so good find. Nothing you have to do to run it. But be aware of two things: 1) Bio-diesel is a great solvent, it will take out all the nasty things that have accumulated in the tank and flush them into the fuel filter. If you haven't changed your filter recently do so, or keep a new one handy in the vehicle so you can switch it out. This is really only a problem on vehicles that have never run bio before, and are older and higher miles. Even the oldest of our vehicles are only 5 years old, so they probably haven't had enough time to buildup stuff thats gonna clog your fuel filter the second you put bio into it. 2) Gel point/cloud point. B99 will start to cloud around 35F, if wherever you live you will be seeing nights down around this temperature before warm weather hits I would fill up with about half b99 and half #2 diesel. This will lower the cloud point quite a bit and should prevent fuel gelling issues. Even so, adding a little power service and keeping some diesel rescue stuff around wouldn't be a bad idea for ANY diesel owner. |

Not really, but if this is your first time running bio fuel it will most likely clog the fuel filter after a while. Bio acts as a solvent an will clean out any built up garbage in the tank, which in turn gets caught by the fuel filter. Run a tankful and then change the fuel filter ro at least have one on hand ready to go in. |

Newport Bio-Diesel sells to the public for 3.20 a gal. http://www.newportbiodiesel.com/ Onsite fill up, so since I am at the Navy Base, I am not far away. Thank you, it should be interesting to see what ends up in my fuel filter. they did recommend going done to like almost b50 during the winter. |

Gel point can vary a lot depending on the feed stock used for production. The place I buy from uses multiple suppliers, but seems to be mostly palm oil based. This clouds around 50F. I have gelled B50 with an overnight low of 28F (that's 28F for maybe an hour). We had so many cold snaps in FL this year that I gave up and ran straight dino through the winter. I'm back to B99 now. I began burning B99 in the warm months around 30K miles (87K now). |

Wish I could find a good cheap place near me to get bio. Even if it was the same as dino I'd buy it Cus I believe in it as a renewable energy. The place I used to go burned down  I could get my own used oil and make it myself if I had a safe area to process it. |

Lol nothing to be sorry about, we basically said the exact same thing(which gives ceedence to me and my statement). I just like to point out that I managed to beat you to the punch by a few seconds.

Other than what Sir Sam and GDE posted, I will add the following about biodiesel • Lower fuel economy and power (10% lower for B100, 2% for B20) • More nitrogen oxide emissions I ran B100 (actually 99) for a short while in my CRD and TDIs. At the time, the higher cost of biodiesel purchased from a Denver Co-op and the decrease in power made it a no-brainer to stick with B20 and lower blends. However, if I could get B100 cheaper than diesel-*F*, could you sell me some of your stash?- I'd gladly put up with the decrease in power. |

We have run B99 from a small fuel company in Cumberland, RI. I would say fuel economy dropped more like at least 15%. It more than negates the lower cost so there is no real saving with this supplier. I put a couple quarts of it in with each dino fill-up to help with reducing injection pump wear. DOC |

However, if I could get B100 cheaper than diesel-*F*, could you sell me some of your stash?- I'd gladly put up with the decrease in power. The "more nitrogen oxide emissions" needs to be clarified a bit. The vast majority of bio fuel studies on diesel engines show bio to output lower particulates and increased NO2 and NO3. The problem is most studies just change the fuel and do not change the engine calibration to match the fuel properties. Since bio fuel has much higher cetane ratings (55-65) it auto ignites faster than #2 diesel with cetane around 40-45. The earlier combustion leads to the higher levels of NOx emissions. If the timing was retarded a couple degrees the NOx emission drop back to the same levels of #2 diesel and still have less particulates. In the future as more diesel engines get combustion pressure sensors built in they will be able to adjust the injection timing based on the rate of cylinder pressure rise in a closed loop feedback internal to the ECM. This will help make diesels more "flex" fuel capable with less noticeable differences in engine operation. |

GDE, With our CRDs, can the injection timing be altered at all through the software? So, could your new tuners offer the ability to alter timing slightly to adjust for different fuel types? Thanks, DOC |

Now that would truly be the be-all end-all for tunes, IMHO. An Eco-tune that expects a 45-48 minimum cetane and improves fuel mileage from the factory tune. I would consider buying that. |

Last summer I was running B99, and I started having very bad issues when starting. Very hard starts (grumble, grumble, grumble, then turn over, shudder, shudder, to finally smooth running) the whole startup process took, if I remember right, 15-30 seconds. I have a friend who is a great, trained mercedes, mechanic, however not familiar with the Jeep. On hearing the hard start he thought it was an injector issue, he ran lots of injector cleaner through the system which didn't help too much until I fueled up with regular diesel. I so want to run BioDiesel, but don't want to try again because of my past experience. The guy I got the fuel from seems to be the only guy in town making it for sale... Does this sound like bad bio diesel to you all? Any one else have any issues like this? Any suggestions? Sidenote: while in my friends garage, he took out the stuck EGR, cleaned it up and got it unstuck. No codes since summer. |

After 2 fillups, I see no difference in mileage and a much smoother running machine. I've had to mix to at least b70 as it's still down to 20's here. The biodiesel provider , newportbiodiesel, just finished their federal accreditation for this year. They've pushed over 1 million gallons of b99 into the fuel stream. As long as the price differential works I am staying with them. I'm happy to have a vehicle that has an option, I hope to continue with this little beast for a while |
