What you see for sale is probably 80% dino/20% biodiesel (B20). Definitely worth running as it provides good IJP lubrication, and you should not notice any difference in mileage. Pure biodiesel has about 90% of the energy content of dino, and you might see a slight drop in mileage running B100.

B100 is over $3.00/gallon here in Denver. If you can make it yourself, your fuel costs drop to less than $0.50 per gallon.

Last I heard this past winter the people up north running the B100 and PS Biodiesel Anti-gel were still having to mix it with dino stuff to keep it from gelling and that included some who were using World Enegry Bio fuel.

Last I heard it doesn't get -10 to -40 below in GA, coldest it got here last winter was about 0 F for a few days. We do sometimes have colder winters, as does GA, but if I remember my days in Columbia SC correct the winters there are seldom in the single digits. I lived in SC from '75 to '81 and never saw a day of single digit weather, did see a 13" snow in Jan 79 and I think a 8 or 10 incher in Feb or Mar of '79 or '80

I will admit not keeping up with B100 news as I should, the reason is I'm surrounded by soybean fields and the stuff is still about $3.00 a gal. There is prospect of lower prices in the future if the B100 CO-OP plant gets the funding here locally.

Also B100 does start getting thicker at about 75* F, but not enough for problems with astm standards. For that matter you or I an our old MB's would never notice the difference. However a new VW PD TDI (Pump Injector, Turbo Direct Injection diesel) with normal IP pressure of 27,000 to 29,000 PSI are effected by just slight decreases in flow capabilities and may have problems with these slight increases in "thickness" of the fuel.

This page has some specs on the diesel in the 2005 Jeep Liberty.

First, I'm surprised the diesel engine's not MB sourced. Second, belt drive for the valves? Is that already done on some diesel engines? Third, a question really, is it true the common rail, super high pressure systems don't do well on bio or WVO?
Thanks

Plenty of people are running BioD blend or straight in common rail engines without issues. Just look around on the BioD boards. RT

MB (DC) owns DD which owns VM, so it is MS sourced.

VW has done it for years with no problems, current belt's are 100,000 mile change out.

No, the problems come from water contamination and fuel viscosity change from temp drop, some concern is voiced over temps even as high as 72* F and problems with bio fuel at sub zero temps. There is a lot of heated (sic) discussion about fuel flow by various groups, real problem is in my opinion VO & WVO and poor mfg of home biodiesel.

You will see many more diesel powered cars, but it will be ten or so years. Wait til gas is $6.00 a gallon, lots of things (including not using them) become viable alternatives suddenly.

T. Boone Pickens (I think, may be someone else!) has publicly stated that he expects world oil production to peak about Thanksgiving Day 2005 and drop of pretty fast after that.

BioDiesel works just fine, with the exception of a fairly high pour point. This can be corrected with some work, right now it's usually just plain vegetable oil derived methyl esters, nothing else. Same process works just fine with animal fat, too, so expect the market for waste edible oil to take off when diesel hits about $2.50 a gallon (early next year?).

Biofuels are the future if we want to drive cars and ship by truck, otherwise I'd suggest moving to where you can walk to work -- personal automobiles may last 15 more years, but it's not gonna be much more than that.

Hey all

If you are interested in B100 or B20 ( 100% biodiesel or 20% biodiesel) go to journeytoforever.org. This site has more info then you could read in a week. BioD burns cleaner cooler and quieter. It is easy to make at home for less then a $1 per gallon

Ps I am looking for a '93 E300 2.5 (or newerTD) in immaculate shape, for cheap and near N.W. Montana. Anybody want to drive their MB to see Glacier national park?? I think I have asked for too much but you never know what you will get when you ask for the world.

Car and Driver actually did mention bio diesel in an article about eight months ago or so about the availability of diesels. They looked at an MB, a Jetta TDI and something else. They also mentioned old MB 300D's and kind of took a crack at them, and only brought up bio-diesel to make fun of it.

C&D is an alright car magazine for what it is, but they tend to limit their automotive enthusiasm to pretty much one kind, contemporary and cool, and an occasional Hyundai/Kia or Camry test. Bio-diesel isn't going to register on their radar I don't think.

Most of the media blurbs I read, hear or see make automotive technologies seem mutually exclusive. I attribute this to the business factions pushing the different technologies. For instance have you heard anything about a diesel powered hybrid? The media seems to want us to believe you can either have hybrids or diesels but not a diesel hybrid. "Our way is the only way", not.
