I've run biodiesel and didnt like the results. Of course my truck is built for go fast so I expected I would have some performance issues. For a tow rig or daily driver it seems fine in the summer. BUT, like I said before you will get parrifin build up in the tank and when you start running straight disel again it strips the parrifin and sends it through the fuel system. Better carry several spare filters with you. CHenry may be able to give a little more detailed input as he runs it year round and has a pretty good setup.

 

well if it needs to be heated to flow i dont think that would be too big a problem in houston haha

 

Yeah, in Houston, and most of Texas for that matter there isnt too much of a problem. I've heard of a couple of cases with gelling fuel but they were an easy fix. Of course the farther North you go the bigger the problem.

 

I'm no Bio-D expert as I have never made it or ran it in my truck. can't buy it anywhere in OK either.
I will tell you what i do know though... yes you can run it year round but blending with diesel in winter is a good idea depending on yer geographic location. Whit, WY gets way to cold to run 100% Bio in Jan. But a 10% mix i would think is okay and then in March you could increase that mix.
Bio is a PITA to make and if you are prone to mistakes, you will hurt yourself or those around you. The Methodox fumes are leathal, the Sodium Hydroxide is Caustic and the Methanol is more flamable than everclear. These are facts, not my opinion and this isn't something i wanted in my garage with my kiddo running round...plus i am prone to the occations stupid **** syndrom and i would hurt myself.
The straight vegi conversion i have has now pumped approximately 2200 gal. of vegi oil through my PSD without any problem and Vegi oil is not harmfull to handle. Its can fuel a fire out of control but like diesel its hard to light it. So its more safe to keep around.
I reccomend a Vegistroke system for your work truck or dayly driver if you want to save a little cabage and keep the air a little cleaner.
They make a conversion for the Dodge too.

Let me add, i don't mean to diswade anyone from making bio-D, theres plenty of people doing it and the number of deaths related to Bio-D is small, they do happen though so just be carefull and do your homework first.
To my knowledge no one has ever died from using straight WVO unless they spilt it on the floor causeing them to slip and hit there head... . Its some of the sliperyest crap known to man.

 

There is no paraffin/wax in bio diesel , 20% bio in cold weather works , many standard anti gel additives work with bio , I use Amsoil cold flow , more than about 5-10% is bad for common rail systems ,
If you work for a living , you are working to put diesel in your truck , bio cost less , so your making more money per hr.

 

Oh yes there is.

 

No, theres not, not if it was properly made, the glycerin is what your refering to and that is removed durring the chemical change process, transertification.

 

It is not completely removed. One of the by products of biodiesel that sits in a tank is the chemical reaction from oxidation that causes parrifin. Thats why the tank gets coated.

 

Could give more details , sources , I have been following many studies , use commercial for a few yrs , a few bio forums ect , have not come across this , until I find facts & more about where they come from , it a wifes tail .
There is too much misinformation out there to take off hand .

 

If you are finding a waxy substance in your fuel system when running biodiesel, it is either the high-freeze point esters or under-reacted fuel leaving a vegetable oil/glycerin film behind or something.

I've seen some pretty crappy biodiesel.. Some people don't measure anything. they just dump in chemicals and hope its good.

Seems that titrating is to complicated for them but its not much different than checking the chlorine levels in the average swimming pool..
