I am just wondering is anyone running biodiesel in their truck. I know it says we can run B20 but i have been putting 40 to 100% in mine. It runs fine. Also notice that the regen very seldom come on now. Is there a reason why we cant run more than 20%? From what i have read biodiesel is a better quality fuel than the ultra low sulfer diesel you buy at the pump. Just thought I would through this out there.

 

Glad you did.... Reason why is your putting your warrenty coverage at risk in the event you have a fuel system related failure.

I would say one reason why we can burn more than 20% is because bio absorbs moisture and moistore in the fuel system can cause rust in the hpfp. In the event your hpfp would failure, the rust is the tall tale sign of bad or incorrect fuel and your warrenty is "game over".

Stick with B5 if you gotta have bio.

 

How much less water will 20% Bio-diesel absorb? I guess about 80% less, but if the 20% Bio-diesel has water in it wouldn't it still cause rust? I see what you are saying there Troy but the water in the fuel thing and the little bit of rust in HPFP causing Ford not to warranty the fuel system is kind of irritating. So when the fuel system goes out what is going out and is it caused by water? I started another threat about the water in the fuel system so I won't get off track here. I thought about running bio-diesel but it is not available here and when it was, it was more money so I never tried it.

blieux1, I think it is a gamble, like playing the lotto in reverse. If your numbers come up you loss. Need to do more research on the actual cause of the pump failures and if indeed they are water related I would have to think twice about running more then the 20% just in the fact they could and more then likely would say see I told you not to run more then 20%.

 

So is this water in the fuel thing something that only affects the new ford trucks? I have run 100% bio in my 2000 ford for years and also in a 2006 dodge with no problems. If no air is allowed into tanks how can fuel absorb water?

 

Some ideas.
1. Doesn't bio fuel hold a higher water content? If so, when it sits still for a few days doesn't the water separate into the bottom of the tank? For some reason I always thought that biodiesel needs to be stirred up frequently so the water doesn't settle out of it.

2. The problem with 2008 and newer trucks (diesel engines, all brands) is that the fuel rail pressure is over 26,000psi. Whatever effect 100% biodiesel has on the fuel pump and injectors is what the concern is.

3. 100% biodiesel has a much lower btu rating than diesel fuel. I suspect the cetane rating would be much different as well. I would assume that 100% bio would put a strain on the ECM to control emissions, fuel burn rate, and soot control/DPF handling.

All I'm saying is that I'm not sure about what problems there would be, if any, but these three points I bring up would seem to be the biggest concerns. Your 2000 motor is much much different and much more capable of burning alternative fuels. I have a friend that mixes half diesel and half transformer oil to run in his 2000 cummins 12V engine. Runs great, smokes a little more, he gets half his fuel for free from me. (Transformer oil is the new kind that has no pcp's in it or any of the other bad stuff)

 

Bio diesel has a tendency to absorb water. Water can cause your HPFP to rust internally and any warrenty coverage on the fuel system will be voided.

Make sure the bio diesel is fresh and hasn't sat around more than 1 month.

 

I miss my 7.3 I could run crude oil in it, and it ran better

 

Actually biodiesel has a higher cetane rating than diesel, the US has the lowest rating diesel in the world imagine that. Every thing i have run on bio it has improved its performance hence the less frequent regens on current truck. I understand the water into fuel and harm it can cause. Like it was said i guess i gotta take my chances.

 

Keeps us informed. Do you make your own or is available locally at a station?

 

Yes I do make my own. I put it in a sealed container and its never opened until it is empty again.

 

That's cool I don't know a whole lot about it, how much do you make at one time? I'll do a search on the web. I'll have more questions later, LOL

 

I totaly agree with you here....I run up to B-20 in my 10' and think I am going to increase it as well. I buy commercially made B-99 and splash mix myself, I have been doing so since 2007 and did the same in my 06'. I have yet to have an issue.

 

I have the ability to produce a 100 gal at a time. I currently have over 3000 gal of cooking oil on hand to make it with.

 

That's a lot of cooking oil. Cool

 

How much bio diesel will you yield from 3000 gal of cooking oil?
