You all need to take a look at this...

I'll let the pictures do the talking.

First one is a customer of mine who bought the ~$3000 kit to make biodiesel in his garage. He drives an '03 Common Rail Dodge. He ran BioDiesel exclusively for 6-7 months. He has dual fuel filters on the truck. He quit running it because of the cost of replacing the filters offset the savings in fuel. They constantly plugged up and required changing.

The picture is of his Fuel Control Actuator valve we had to replace. This part is a component on the Bosch CP3 injection pump. This is after all filters and heading straight into the pump and injectors.

His valve is on the right, a normal valve is on the left for color comparison.

The slimy brown film is everywhere. It's inside the pump,Injectors, all the injection lines, etc.

The next few pictures are from a VE Injector pump off the '89-'93 Cummins Engines. The customer had been purchasing what he THOUGHT was B20 BioDiesel from his local supplier.

The point of this is not to scare people from using BioDiesel. Just make sure you know your supplier. Ask about their filtration methods. How many microns do they filter down to? Study for yourself and ask questions.

A renewable fuel resource is great for all of us. But as with any business there will be people out to make a buck that will cut corners to save a few pennies. Purchasing fuel from these guys can literally cost you THOUSANDS of dollars in repairs.

Be cautious!

That is just nasty.... :wow I dont' even have to know anything about trucks or Diesels to know that is nasty stuff.. No more thoughts of using biodiesel here.. :nono :nono :nono

I get my BioD from http://www.sqbiofuels.com I'm reasonably sure they have better quality control than that.
