    I did see some info. about that...I have a plastic tank in my worries. Lots of anecdotal evidence floating around.

    Ron - are you forced to use B15 if you don't like it?

    I'll end up using the rest of the tank as an additive to cut the petro stuff. Once it's down low enough I'm filling it up with petro to make it a 20% blend.

    Zab - thanks for the info.. Any suggestions on what to treat this stuff with?

    Well not sure about any of this as I am not a mechanic. All I know is when I took the pump off and took it to St. Louis Diesel Injection Service, they told me the pump was shot from running Bio Diesel. They told me that the pump was not properly lubricated and that is why it caused the pump to fail pre maturly at less then 15,000 miles. Weather it is just a bad fuel or not lubricated properly who cares... why take a chance at 1,000 a pop injection pumps, and the down time while it is getting fixed.

    nothing but trouble here with BioD even @ 5% our problems began with we got an animal fat version of bioD and the next run a veggie BioD the two did not like each other. played hell on the filters on the pump and buses...Had to have a 2K tank pumped and cleaned. we go 5% biod every other tank full problems have lessened. but I won't run it in the skid or back hoe in the winter time since they sit out side from time to time..

    replace filters on 26 transit buses.

    animal fat biodiesel, never heard of that before, have to admit that sounds like a terrible idea.

    had a guy i know that ran used motor oil in his 7.3 that he filtered down using home water filters. he ran some ridiculous percentages as well, like 50% he told me once???

    said he read it on some diesel forum, had issues with injectors etc... but he still does it.

    i drove the truck once and my eyes were watering from the fumes.

    edit: i never fully investigated this option until just now after i typed this response, and it seems pretty established. i might set something up to be used in our diesel equipment, id never try it in the trucks though...

    It's bulk fuel from a better (and cheaper) dealer.

    I have made biodiesel for many years and have had no problems. However, I use a fractional distillation process that also works on used motor oil. Using transesterfication is a bad way to make biodiesel in my opinion. My dad has run his diesel Mercedes on waste vegetable oil for many years, and my own pickup truck runs on biodiesel and waste vegetable oil at the current time. My experience has been that everyone else I have known who has made alternative fuels has given up. Even myself, I purchased biodiesel from a supplier and it caused my dozer to lose power and die. Further analysis showed the fuel was not correctly washed. Classic diesels without electronics should all run on vegetable oil as Rudolpf intended.

    Be ready to change filters. Soy bio is a great tank cleaner.

    i have run my 7.3 ford on up to B20 biodiesel. it is noticibly quieter and smoother running with no loss of power. i liked the lubrication qualities as opposed to ulsd. until it is better regulated i'm not sure i would run more than B5 in a newer electronic truck.
