Default INFO: Bio-diesal

Here is a link that will tell you most of what you need to know about bio-diesel. There are a few things to clear up here;
1. Bio-diesel is made using waste vegetable oil (wvo from here on out) or waste animal fat, it is not plain old vegetable oil. It has to go through a process called transesterification where you mix lye and methanol into the wvo mix it and allow it to settle. Then the glycerol is washed out and tested. Then you have to allow the water to settle, drain it off and then give the bio some time to dry out.
2. The jury is still out as to whether it has enough lubricity to be safe in a late model diesel. There are just as many good testimonials as there is bad.
3. Bio is more corrosive, it will eat all the rubber out of an older fuel system (I believe early 80s and back). Usually when someone starts running bio they change the filter after the first tank or two because it eats all of the gunk out of the fuel system.
4. Bio cost an average of about .50 to .75 cents to manufacture after the rig has been built and considering that you can get the wvo for free.
5. Bio has less btu than diesel so your fuel mileage may go down slightly. (use more fuel)

I know I submitted this as a response to another thread but it is good info and posted in the proper place I feel it will get the most veiws.

you need to watch the episode of trucks with stacy david of the effects and benifits
of bio diesel when it is done right.
you know as well as i do that most of the problems with bio diesel
can bounce back as human error, left something out, or thought their short cut
was better then going by the book.

I think the problem with biodiesel is that there is not official standard yet which makes it hard to produce a quality fuel. It is also hard to issue a warrenty for biodiesel too.
