Hi Relfex. I appreciated some of your posts towards the end of this thread about diversified energy production. Some of your blanket statements on biodiesel however should be clarified. Biodiesel is not a solvent of "everything" that it comes into contact with, anymore than petro-diesel is a solvent of "everything" that it comes into contact with (yes diesel is a powerful solvent contrary to some of your earlier statements).

Reflex wrote "Diesel when it gets into your oil does not break it down like gasoline and biodiesel do. This is one reason oil changes in diesel engines are 2-4x less frequent than they are on gasoline vehicles. This is my point, it increases wear via multiple methods, a major one being that if you adhere to oil changes on a 'normal' diesel schedule you will have problems that will not happen on regular dino diesel.

Really? Maybe you should tell that to some of the Powerstroke or Duramax owners who have had their whole engine replaced because of diesel in the crankcase with only 30k miles on the clock. Diesel, Gas, WVO and Biodiesel are all very detrimental to engine oil. If you are getting enough fuel past the rings and into the oil its time for an overhaul. There is no evidence of increased need for oil changes when running bio, just check some of the posted UOAs on this forum. Many new gas vehicles have oil change intervals similar to our KJ CRD.

It is not a solvent of automotive metals at all, or perhaps you know of an alternate kind of chemistry unfamiliar to modern science. You are very pro-algae biodiesel(which is good) but bash vegetable biodiesel as being very bad for engines. perhaps you do not realize that they are both the same fuel, FAME.

Reflex wrote "I don't claim otherwise, I am aware that algae has the same properties and will also degrade the lifespan of an engine. But my entire argument is not based on engine life, and if a solution can solve the energy independence issue, a somewhat shorter lifespan would be perfectly acceptable to me.

Yes you do claim otherwise. Or does so much misinformation in your head cause memory problems?

Reflex wrote "Diesel in general is a lubricant, but Biodiesel is a solvant just like gasoline. It will eat away at an engine that was simply not engineered to run with a solvant inside. It will degrade even the metal over time. Ever wonder why gas engines last roughly half as long as diesels despite lower pressures/compression? Diesel people like to believe its 'superior engineering and tolerances' but thats only part of the equation. The fuel is the other part." http://www.lostjeeps.com/forum/phpBB3/vie ... 16&start=0

Take a course in chemistry, then get, read and understand a Comprehensive book on diesel theory and mechanics (Bosch makes a couple of good ones). Don't just repeat what "some guy" said about how biodiesel dissolved the engines in some secret government tests as fact, because it misleads those who are genuinely trying to research a more earth friendly fuel for there vehicles as the thread author was doing.

Yes most independent mechanics love it when fleets switch to biodiesel because they initially get a lot of business from plugged fuel filters and crap caught in injectors, but once all the nasty stuff is gone business drops off because the fact is that engines run better on a higher lubricity, higher cetane, lower soot fuel than Dino-juice. While vegetable biodiesel will likely never be able to meet the demands of transportation, it will never displace food crops. Even bio produced from soy which is one of the poorest gallons per acre oil crops, creates a high grade soy meal byproduct or perhaps the oil is the byproduct depending how you look at it. AT any rate, biodiesel should be encouraged as a positive step toward petroleum independence.

Reflex wrote "It already has displaced food crops. Even worse, its displacing natural areas, and destroying rainforest. Deforestation in southeast asia to support palm oil based BD has approached 80% in some countries according to National Geographic, which made a cover story out of the issue last year. Corn prices(due to ethanol, not BD) have skyrocketed, people in Haiti have been reduced to eating dirt as a result(yes, dirt from the ground). This is the human toll of crop based biofuels. The UN has called biofuels a crime against humanity, and they are correct, as we are unwilling to conserve and give up our luxury in the first world in order to save the lives of those less fortunate.

No, biodiesel has not replaced any food crops. if it had there would be a world shortage of food. There is however a surplus of millions of tons of food which rots in harbors and silos every year. The inhabitants of Haiti have experienced hunger and starvation for the past century. It is nothing new. It is a political problem and always has been, politicians blame on it on anything they can and get every poor sap who wants to sound like an expert to bite on it, as evidenced by your using corn ethanol as an argument against biodiesel. By the way, corn is not the largest component of the Haitian diet, cassava, rice and beans are. Even though there is an ongoing ecological disaster in SE Asia, it is not from the fuel, it is from the methods used to farm it as well as abuse by forestry companies.

There are very sustainable techniques for palm oil cultivation which are also economically and environmentally feasible.

It's just very strange that you seem to come down so hard on Biodiesel as a segway towards more sensible transportation alternatives when it just makes so much sense to promote it.

Reflex wrote "The real solutions are simple:

1) As UFO said in another thread, CONSERVE!
2) Pour money into research for next generation renewable energy sources without simply dismissing critics(like myself) who often see the long term issues long before the proponants do.
3) Food should go to the hungry, not into cars.

To these 3 points, Amen!
Your statements on nuclear energy as a superior source of energy in the alternative energy thread appear to be very well researched.

Where have I ever claimed that the problems inherant with BD and engine wear do not happen with algae based BD? I have said that algae based BD has the advantage of not consuming cropland, and having an energy density per acre to actually have a realistic chance of displacing a significant, if not most oil for fuel consumption, something that crop based solutions can never promise. I have never made statements about algae and engine life, after all biodiesel is biodiesel.

Its funny you should mention Bosch. You may wish to read what they think about BD and their injectors. In fact, ask any professional mechanic what they think about BD and injectors in general. No need to rely on what I am telling you that 'some guy' said about it, the professionals have already rendered their verdict.

This is flat out denial of the facts. There not only is a food shortage, but it is causing riots and starvation in places besides just Haiti. All over Mexico and central America, some parts of Asia and Africa food imports have diminished due to the massively rising costs and diminishing food aid.

BTW, its a common misconception that food 'rots' in storage due to overproduction, in actuality production is carefully regulated, and farmers are either paid to leave fields fallow, the excess is used for animal feed or fertilizer, or it is donated as part of foreign food aid. These supplies have dried up and the global prices of corn, wheat and other staples have skyrocked, as much as 400% in some markets. Look it up, its all over the foreign press, although rarely covered here.

As for palm oil, its obviously easier and cheaper to do it unsustainably, by the current regulations it is simply leading to deforestation, the EU(the primary importer of palm oil) is attempting to rectify this now, however that does not change the damage that has been done, nor the fact that it is likely to continue to be done when less scrupulus nations begin to show demand.

I come down so hard because people are treating it like a magic bullet. It isn't, and in fact it is currently increasing our dependence on foreign oil and our environmental footprint. There is no guarantee that it will ever solve the problem, and without that guarantee jumping on board and as a result entrenching it in society(via subsidies and public perception about what is 'green') we make it much harder to change course later on should it become clear that its not the answer. Its taken us a forty years to consider switching from fossil sourced oil, and thats with us being aware of its issues. I'm not ready to jump from that frying pan without being certain that there isn't a roaring fire where I'm going.

Just for the heck of it, the other night I did a search on military testing of biodiesel. While I'm not sure if the test Reflex mentions is documented anywhere on the web, the reports on military testing I found did have the following common points -

No evidence of increased engine wear, increased maintenance, or other problems caused solely by biodiesel use, no changes needed in maintnenace routine or operating practices - nada, none, zip.

Contrary to what the EPA has stated, they found no increase in NOX emissions when comparing biodiesel to ULSD.

Biodiesel was tested in stationary, mobile, and vehicular applications.

Biggest hurdle noted was ensuring that the fuel had been adequately processed and was of high quality.

One study applicable to us was done at Fort Leonard Wood, using roughly 380 Humvees and other diesel vehicles. No additional problems noted that could be attributed to biodiesel use - in fact, they noted that the maintenance routine for these vehicles went on without any changes needed. If you do a Google search you can easily find the same study.

I'm sure people have had problems running poor quality biodiesel. But then people have also had problems running poor quality dino diesel as well - I've had 3 clogged fuel filters to attest to that. Crappy fuel is crappy fuel, whether it comes from a soybean field or an oil well.

Yeah, I read the same study and one done by the US NAVY. They both show the same findings, No increased maintenance. But no mater how much scientific evidence, logic or reason you can bring up about certain subjects, some people will still hold on to their belief in voodoo and bad mojo and calmly assure everyone that biodiesel is taboo and will melt your engine if you use it. Although there other readers of this thread who surely enjoy reading it, I've decided not to post any more arguments in favor of biodiesel use because it just makes me look like I'm in a pi$$ing contest with Reflex and others, which I'm not. I think that the subject has been covered very throughly already and needs no rehashing.

Penn State is currently doing extensive testing on Biodiesel use, and its effect on Ag diesel engines:

http://domesticfuel.com/2007/11/08/new- ... biodiesel/

Penn State is reporting no adverse effect on the equipment being tested. New Holland (US manufacturer of Ag equipment) has recently approved the use of B100 biodiesel in their equipment. It will be interesting to see the results of further research. I have run many tankfuls of B100 in my Dodge Cummins 2500 4x4. My only adverse effect was a piece of aftermarket fuel hose that became spongy. Also running bioblends in my MB 240D, and 2006 Jeep CRD with no problem. One of the reasons for the longevity of diesel engines vs. gasoline has been the superior lubricity of diesel fuel compared to gasoline. There are interesting test results on the internet, showing that biodiesel lubricity is superior to petroleum diesel, even when the petro diesel has lubricity improvers added. If you have personally run biodiesel blends, you know that your engine runs much more quietly on biodiesel. The ignition process of biodiesel is smoother than petro diesel, lowering stress on pistons, rings, rods, and crank.

Everyone on this thread has provided some great insight to biodiesel. As a matter of fact, all this Biodiesel talk is making me hungry for some Biodiesel.

But it seems (at least in my area) that more and more places have stopped carrying biodiesel. :cry:

4 out of the 5 distributors in my area have now stopped carrying biodiesel saying that the cost has gone up and the demand is low.

I’d give anything to go to the pump and fill up with at least B5. I’m tired of adding all these stupid additives (power service, 2 stroke, Amsoil concentrate, etc) all the time just to ensure some lubricant is in the fuel. So tell me guys, are more bio facilities being built? What is the future for biodiesel? I’m not kidding, there are more ethanol plants built or being built than Wal-Mart stores out here. :shock:

I will admit, we do have a lot of corn and milo to feed the ethanol plants, but we also have several million acres in soybeans. So why not build a biodiesel plant? :idea:

The Economic Developer here in Ulysses is talking about building an algae biodiesel plant, but that seems to be far off. I was hoping that you guys would have some insight on what you think the future looks like.

Two situations currently drying up the supply of biodiesel in the US are thanks to the same people that have created the current ethanol mess - the US government.

Originally, biodiesel producers and retailers could only take advantage of tax credits if it was made from vegetable oil. In the last energy bill, one congressman got the wording changed to include biodiesel made from the byproducts left over from food industry processing - fatty byproducts from poultry, beef, etc.

Unfortunately, the way it was worded, the IRS was able to hand down a ruling (via some prodding from the White House and certain lobbyists) saying that if the oil companies included a certain percentage of biodiesel feedstock somewhere in the process at their existing refineries, they could call the resulting mix "renewable diesel", and claim the same tax credits and subsidies that were originally intended solely for small scale biodiesel producers and encouraging the addition of new biodiesel refining capacity.

The end result is that the major oil and food companies are buying up all the existing biodiesel feedstock they can find and adding it in at their existing refineries to claim the tax credits. Small scale biodiesel producers have seen their feedstock supply dry up and the price of what is available skyrocket.

In addition, the loophole created by the IRS has also allowed the practice of "splash and dash". Bring a tanker of of B100 into a US port, add enough dino to create B99 and get the $1/gallon tax credit, then promptly sail it to another country where it can be sold for a higher price.

I'd imagine they're doing the same with US produced B99 and "renewable diesel" - after getting the tax credit, it's promptly exported to another country where it can fetch a higher price.

There are a few things that I don't have a good grap of concerning biodiesel vs. petro diesel:

1) While it has been proven that bio lubes better, how much damage is being caused by running petro? Will the engine need an overhaul at 50,000 versus 300,000 or is is a hair splitting thing where you will be able to go 310,000 instead of 340,000? If we're splitting hairs here, I'm not interested in the lubrication benefits. I'll most likely get a new vehicle before it matters.

2) With the price of crude oil as high as it is getting, sooner or later, it's going to be cheaper for oil companies to use bio stock or recycled cooking oil to make fuel. By blending it with petro, they could end up saving money even without a govenrment handout.

3) If biodiesel runs cleaner and cuts down on polution, then instead of forcing manfactuers to change their engine designs, why doesn't the government mandate that fuel contain a percentage of biodiesel. I'm betting this change alone would clean up the air more than all the EGR valves that fail and damage engines.

I heard from a friend of mine who is looking for a job that a nationwide company is going to be building a plant here in Kansas City Missouri soon. A temp company offered him a job at the place. I don't really know anything else except the person looking to hire told him that he would be making bio-diesel.

one ques. and another point...

REFLEX:

does ABD require Methonol to make?

if not i might have to "jump ship" ive been making my own for close to 2 years now... when i started metho was only $1.05 gal now it pushing $4.95 gal!!! so just to buy one 55 gal drum that will make 11 batches of 25 gal each is costing me $273.00 / 275 gal made per drum of metho = $0.99 per gal is what im paying. now that still cheeper than what the pump is BUT, the real ques. is: What is my time to make it worth now?

this just shows MY problem... however you could see how the cost of ABD or VBD could run up to current market of Diesel dueto Metho prices going up. and from what i have been told metho is only made at two plants, one in germany and another in europe somewhere which burned down last year...

I do not know the processing requirements for ABD yet, its not at the mass manufacturing phase and there are still debates as to what type of algae is ideal and how best to extract the oil. I'd say its around 5 years or so off from mass production based on the reading I've done. That said, its one to keep an eye on since it has the potential to actually produce enough fuel to replace imported oil, something that cannot be said for any crop based solution.

WASHINGTON - The widespread use of ethanol from corn could result in nearly twice the greenhouse gas emissions as the gasoline it would replace because of expected land-use changes, researchers concluded Thursday. The study challenges the rush to biofuels as a response to global warming.

dieselenthusiast · **Posted:** Fri Feb 08, 2008 1:28 am

Okay, those who are living in the state of Washington or near Spokane, there is a guy by the make of John Torkar who works at Advanced Diesel. He says that biodiesel can cause and does cause injection pump leaks. I believe (don’t quote me) that he also said biodiesel can contribute to gumming up the electronics. Anyway, this might be a good person to contact if you have questions about biodiesel and the possible impact of using it. Due to the high use of biofuel in the state of Washington, John Torkar sees a lot of it and his business has increases considerably because of it. I will provide his phone number and address so you can contact him directly. This guy knows diesels and is highly respected and highly reputable.

Hello DE. As has already been covered, biodiesel will most definitely cause leaks in the seals on older injection pumps as everyone who has tried using it in an old early 80s VW can tell you. It however will not degrade the newer materials made from viton and similar synthetics. I would tend to view anything that the above mentioned man from Advanced Diesel stated about biodiesel with skepticism, if he did indeed say. that biodiesel was gumming up electronics, as the fuel should not be in contact with any electronics in the injection system except possibly the wif sensor or fuel temp sensor. Rail pressure sensor, and all fuel control solenoids are insulated from the fuel.

retmil46 · **Posted:** Fri Feb 08, 2008 2:03 pm

ULSD will do the same to an older diesel. The injection pump on the '87 MB started leaking like a sieve after the first couple tanks of ULSD, no bio involved.

Around 100,000 miles of testing of B100 used in 1991 and 1992 Dodge Cummins pickups. Interestingly, oil analysis showed lower levels of engine metals compared to the same model engines running petro diesel under similar conditions.

Gee there's a surprise. I think 101K miles is where the engine starts to dissolve though. :twisted:

Must be, since by then the metal content of the oil analysis is dropping b/c the engine is no longer containing any metal, it's all sludge and carmelized grease, right? :roll:

Hmm. 30k miles of homebrew biodiesel (and NOT ONE DROP washed or heated while brewing) through the engine of my VW Jetta, then 60k more miles after that... And at 150k miles, the engine compression was within 10psi of each other on each cylinder, AND at the TOP END of the Service Manual's "NEW ENGINE SPECS" range.

Yea, that engine's life was seriously being cut by half by that biodiesel. :roll:

I've been running commercial BD in various blends up to B100 since I bought my KJ in October. The engine runs noticeably quieter on the bio, and it certainly sounds smoother too. I've never been one to subscribe to the ashless oil additive idea, or dumping in Powerservice constantly... I add PS about 3 or 4 times per year "when I remember" and thats it. But bio... If I can get it, I'm gonna run it, and I'll spread out what I can get by mixing... But I WILL run it. Its better for the engine, and my own tests have proven that.

But Geordi Aren't you worried that you will use up all the country's soybeans by running commercial bio? what will all the cows eat? Don't you know that after the oil is extracted all those millions of tons of high quality meal are thrown away? For the love of god, what about all the starving Haitians?
Seriously though, if I have the choice I always opt for bio for the same reasons that you mentioned. Our little hot blooded Italians just love it's cool refreshing taste and it keeps them from talking back. I've been buying B20 for the past month and a half and it is killing me because I have 1300 gal of beautiful golden peanut oil, 110gal of methanol and 20 gal of KOH just sitting in my buddy's shed but have been working 50 hour weeks and just can't find the time to make any.

Biodiesel - MYTH or FACT?

Who is online
