| Post subject: | Biodiesel Question: B100? |
Hello, I have a new CRD and want to run biodiesel. The two options in my area (Iowa City) are B2 and B100. I like the idea of B100, but wanted feedback. I know Chrsysler says <B5, and B20 would be a no-brainer for me. But can I expect ill effects from B100? It'd be a lot easier than trying to mix my own B20. I imagine in the cold Iowa winters I'd want to mix in petro-diesel. Any thoughts and experiences, good or bad, from running B100 in a 2006 Jeep Liberty CRD? Thanks in advance, Jeff |

I have run severla tanks of B20 without problems. I put about 11 gals of B99 into a tank of Dino last week and pushed a CEL about 250 miles later that I have not read yet but otherwise had no issues. Several here that run B99/B100 report harder starts and slightly reduce mileage on the down side and less engine noise on the upside. I ran my first tank of B20 in December with temps in the teens without issues but a local school bus fleet filling from the same tanks had to go back to Dino due to jelling issues. Of course a 1/4 tank of B100 becomes B25 when mixed with 3/4 tank of Dino so mixing your own blends is not out of the question. |

I run B20 the majority of the time. Just over 19k on the clock, and the only issues I've had is 3 out of 4 glow plugs replaced (all during the summer months). |

I've run B99 with no problems. Typically, I blend it between B50 and B75. I've noticed that B99 runs quieter, but gets low MPGs. I can not attest to long-term results since my Jeep is only 3 months old, but short-term has been fine. |

I've been running various blends since I got my CRD in March. Started with B20 with a few B50 tanks until mid-May when I went to B99/100 through July and early August. On a long road trip I couldn't find any so used dino for 2700 mi and just went back to B20 yesterday. No problems from the biodiesel at all. I did get a questionable tank of dino in Montana that seemed to cause some tranny shudder and hard shifts. As to winter driving, I'd suggest that you don't go over B20 and even a lower blend if you park outside. As long as it's >35-40F you're fine with a high blend. Even the distributor around here, mild Pacific Northwest, uses B50 in the winter. |

Guesstimated B50 here (shhhhh don't tell Dr. Z) with no problems. |

Thanks in advance, Jeff I am limited to two choices for biodiesel, B20 at a pump near work or B100 from an oil supplier 30 miles out of the away so running high concentrations are not practical. I try to patronize the station with the B20 pump as much as possible eventhough their fuel is slightly more expensive. I also buy B100 in 5-gal fuel cans and splash-blend as needed. A 5-10% splash blend into even poor quality dino-diesel makes a world of difference in noise, smoothness, and black smoke. I personally like the way it runs on B15-B20 and willing to pay extra for the stuff. One time, I had @ B75 in mine from splash blending while enroute to the fuel station. Was a bad experience as it bucked & stumbled until I topped it off with D2. I don't know what caused that (uneven blending??, cold fuel??) but it went away and I never tried that stunt again. |

I have run B100 from the same supplier in Iowa City. It runs fine but starts a little harder than D2. It will stumble once or twice before sustaining an idle. I normally run between B20 and B40 blending it myself. |

Running B100 in Madison, WI, on my 2005. Some hard starting, especially with a cold engine, but otherwise it's all good. I've only had it for about 2000 miles, so I guess it's a little early to say how the milage looks, but my feeling is it's a little low. Not to bad though, I'll trade < 10% milage for improved emissions, a little less noise, and the ability to grow my own if I want

I guess that it is kind of obvious that I run B100 (ASTM commercialstuff), and have pretty much stright for the last 6 months. Nothing to note except possible longer starts. EGR was a non-fuel issue, and some say B100 should help with future EGR stuff, but I have doubts. It might be time for a tranny check (sometimes won't go into D from R when its cold), and that isn't fuel related either. But even an enthusiast such as I would be the first to point out: it ain't proven until it is proven and proven again. I know the risk I take and take it willingly. Be sure that you are aware that this is new territory and 10k miles is a lot different than 100k miles of proof. |

I've run full tanks of B100 with no ill effects (not even hard starting). There's a place in Phoenix with really high quality bio. However, it is not always convenient to make the drive into downtown Phoenix, so I've filled several 5 gallon fuel jugs and mix about 1/2 a jug to a tank of dino. I think it's important to maintain some bio in the tank because of its cetane and its cleaning properties. |

I'll chime in on my experiences as well. I've been running various blends since I bought my CRD last October. I have 18K miles on it now. It's been in for an EGR and the tranny TSBs but otherwise runs great. I do notice some hard starting on B100. If the B100 supplier isn't far out of your way, just splash-blend to B20 or so (just fill 4-5 gallons of B100 and the rest w/ D2) and increase the percentage until your personal cost/sustainability meter reaches equilibrium. For me, D2 runs ~$3.20 and B100 is ~$3.50 so there's a definite premium on Bio. But it's worth it to me (I have a 55-gallon drum I keep in the garage and fill the Jeep from there). Mileage difference is in the error as far as I can tell and it's definitely quieter. Wife and I were on a trip a few weeks ago and had to fill w/ D2. At the next rest stop she thought something was wrong w/ the engine as it was "making a rattly noise". 
And for the winter (if you read my profile I ski a lot so am in cold weather) I run B20 (basically try to time my trip so I top off w/ D2 as I'm heading into the mountains so I get winter-blended fuel) and I add some PowerService additive. Haven't had any cold weather problems. I also give it a good 30 seconds of glow plug time even though the light is long out by then. Maybe just superstition on my part but I don't think it will hurt. So go for it. And remember, every gallon of bio you use is one less gallon of oil we're having to pump out of somewhere. |

Know a guy with an MB CDI that has been running B100 summer and B20 winter and he has about 45k miles on the car with no related problems. |

I have been running B20 in my PSD for about 8 mounths, last couple tanks have been b100. The CRD got B20 the first time we filled it (only had it 10 days). Here (Salt Lake) B20 is 10-20 cents lower than D2, and B100 is 40-50 cents less than D2. There are 3 stations with b20 that are not too out of the way....I see no reason to not run at least B20. Well, except I keep getting cravings for french fries

I have about 18k on our CRD with all summer weather at B99, Spring and Fall abt B50, and winter at B20. I have only used about three tanks of petro diesel on a trip where I couldn't get bio... Started using B99 upon purchase. I have had the EGR fail, which is not a fuel issue - in fact B99 should help reduce the issue... |
