I have been around deisels just a few years. You can do as you want because it is only $$$ which is frustrating in itself when your neighbor buzzes up and down the street on french fries, first you need to understand injection.

Biodiesel fuels are formulated in many different blends and concentrations.

Consult your fuel supplier for biodiesel cloud point specification for cold weather.

Blending biodiesel fuel above a 5% concentration could have some adverse affects to the engine.
• Power loss and deterioration of performance
• Fuel leakage through seals and hoses
• Corrosion of fuel injection equipment
• Lubricity of biodiesel and the fuel injection equipment
• Coked/blocked injector nozzles, leading to poor atomization of fuel
• Filter plugging
• Lacquering/seizure of internal injection system components
• Sludge and sediments
• Reduced service life

Raw pressed vegetable oils are NOT acceptable for use for fuel in any concentration. Experience shows that biodiesel is not always conforming to standards.

When using a blend of biodiesel fuel in a rotary fuel injection pump, the engine oil level must be checked when the temperature is -14° F or lower. If oil becomes diluted with fuel, oil change intervals must be must be established by using oil analysis program.

A diesel engine will burn lots of types of oils and is quite tolerant of these products in the short term. The long-term effects, however, are another story. Biodiesel acts as a lubricant, which means that it can loosen deposits that are stuck in fuel lines and in the fuel tank, which in turn could clog fuel filters, injectors or other parts of the fuel system. Ford, General Motors and Chrysler take a stance at 5 percent Bio fuel.
Others, including Volkswagen and Mercedes-Benz do not recommend the use of any biodiesel and note that owners who use biodiesel may not be covered by their warranty if the problem is deemed the result of using biodiesel. Mercedes-Benz new compressed direct injection diesel engines, where the pressure of the fuel being forced through the injectors, is much greater than in the older-style diesel engines.

 

You know what an expert is? I'll tell you, an Ex is a has been, and a spurt is a drip under pressure, and I believe that about sums that up. Yes I will attack anyone who goes into FORD 2006.1 version default mode and quotes the warranty guide to me. I understand injection, bmep, ladder logic, plc's, scavenging properties, thermal efficency, supercharging and many other things that the current 6.0l diesel techs will never learn in their lifetime. Let alone cause and failure analysis. The techs throw parts at it like the plague. I am not arguing that point, they got to eat too. I have also spent more money on gaskets doing an overhaul than any Ford tech would ever spend on an entire engine swap. Again not arguing that. What I am looking for is an intelligent answer, which would not be yours. I spend $13,000 on a prejob plan on the engines I rebuild. Many which were desinged and put into operation in the 1930's and 1940's. They are through technology, meeting some of the toughest emmissions standards around. Why should I believe that the technology does not exist to run 99% bio in a 6.0? Because a Ford Tech said my injectors failed due to not running Conoco/Phillips 15W40. Give me a break. It is ignorance like yours why we are still dependant on foreign oil. The sad part here I that I work in the oil and gas industry, and see a real need for change. I am sorry that you malcontents do not. However I don't want to hear one more bashing about how ExxonMobil made record profits, and all the whining going on about how much these trucks cost us to operate. Because after all, Ford and you said it couldn't be done. I will call especially your bluff, when I am running 99% bio and don't have to worry about who will work on my truck, because I am capable of installing an injector without damaging the o-ring. There are you happy now?

Thank you for a real answer. It may not be the one I want, but at least you are open minded.

I fully understand the concept.

Once a standard is put in place like has been here in Louisiana, meeting or exceeding DF #2 ASE and ASTM standards, what is to argue about that? Unless you get the major oil companies to admit that what we are buying now is really not a standardized fuel grade, I don't see the revelance of that arguement.

Problem is many people have been running concetrations above this and reporting better fuel mileage with no power loss. Which in a Diesel is directly related.

[QUOTE=monsterbaby]Although I don't run a 6.0 (I have a 7.3 and drive a semi but I notice bio diesel posts) I run mine on B25 for the F250 and B20 in the semi (I make my own for the F250 from WVO) the B20 that is put in the semi is bought at a truck stop in council bluffs Iowa and is 2 cents cheaper than the regular diesel.

Ok experts whats the deal here?

Hello, I have some knowledge of bio-diesel, when I worked for the ag engineering dept. at UM one group was running 100% BD in two Cummins motors to see it's effects, this was back in the mid nineties, results actually showed decreased engine wear at 100 K miles. Im not sure what modifications were made to tanks, lines and pumps but the motors ran good and did well. The one problem they did have was water and how it disperses it'self in biodiesel, its much harder for a filter to catch. The ford tech at my local dealer warned me of the same thing the other day, just recently a local station offered B-20 more than one 6.0 owner came in and needed new injectors as water and 6.0 injectors don't play well together. The bad thing is warranty did not cover their repairs due to bad fuel.. Funny thing here is ULSD is reported to do the same thing with water, Guess well just have to wait and see. So I gues my point is a good place to gather data on bio diesel is the AG Engineering journals and farm magazines, although they are probably somewhat biased in favor of BD, also it does work, but not equally as well in all motors, or years of motors. Keep your chin up, do your research, your right it is coming they are producing BD in a commercial plant close to my home now, and with it's lubricative value it will probably become the cheapest additive for ULSD, Hope this helps I'm not a tech, but I read a-lot. Also have you checked out www.greasel.com as an alternative fuel.

 

I agree. It is your truck and your engine, you can do what you want. I would not recommend this practice in my opinion for the 6.0L The power loss will not be on the first tank of Bio.

 

It is our engine and many will do what they want and it is Ford's warranty and they can do what they want.

The problem is, many of those same people running beyond B5 will be among the first to come here and raise unholy hell about those Ford SOBs that won't cover their fuel related parts under warranty.

There is no way to regulate what garage brewers are doing to their bio fuels. In addition, the home grown bio fuelers are circumventing the Federal, state, county, and city taxes. You can bet your butt, that the revenuers will soon be out to get those guys. .Or the local Fire Marshal, EPA etc...

Right now it is a cottage industry...but, it won't take long for the big dogs to go after their piece of the pie. Tax wise and / or control wise.

 

you asked for an opinion, I gave one. You are free to do what you wish, I can only relay fords stance, because they are the ones warrantying this motor. As far as I know, the tech isnt here yet for bio, but it is coming---be patient.

 

The government already caught up to few home brewers and they are finding Bio isn't as cheap now.

 

Guys, I think you are all missing the point here. I am in no way trying to get over on Fords warranty. (in fact I will probably never buy a Ford product again after hearing the comments from tech's in this thread, {after all Ford does pay thier paycheck} they are every bit as sorry as Ford for defending Fords warranty standpoint, and not what is right, but that is not what I am after here, the greater good of this it to tell the Arab world in no uncertain terms that we don't need any more crude from them ever again period) I have one til 100K and am going to make sure I use every bit of it legally. I am not talking about tuners and pushing the envelope. I am talking about a USA produced source of fuel that replaces what we buy now, that all of you seem to blame for inherant design problems of the 6.0. (too clean, too dirty, to wet, to dry, to slick, to rough, ect.ect.) I understand the home brew ect. ect. but once a standard is set, and you can attain it, where is the problem if your out of warranty anyway? Or buying it from a manufacturer or coop that does meet spec?

In my manual ('06) it states Ford approves 5% bio in the truck.

 

I must be missing your point. This is the 6.0L thread, Bio is not friendly, the techs gave you an answer and you do not realize why higher concentrations of Bio are going to damage the injection. Ford Gm and Chrysler do not recognize higher levels of Bio above 5 percent, yet you insist that some conspiracy among the techs and Ford is keeping you from the American dream of being oil independent.

Buy a bicycle with steel wheels and your problem is solved.

 

ford has no choice but to accept biodiesel and ulsd.
it already been in service for 2 years hear bio that is.
2% in every gallon. STATE MANDATED. and there have been quality issuses.
and ulsd has been in service since early june here.
so as far as them denying warranty here for bio has no merit.

 

2% doesn't exceed B5 specs anyway does it?
