I'm not surprised to hear it but don't panic.

HAVE YOU SEEN THIS?

You can read about the bacteria scare and see the comments at the above link.

I can tell you that in the 30+ years I have worked on diesel engines large and small there has always been bacteria in some of the fuel. If the operators are aware of the existence of this "bug" they watch for it and as soon as the signs appear add "bug killer" to the fuel.

I don't worry about what brand I am using - I just tell the owner of the tank to go get some and add it according to the instructions.  As a precaution you should try to agitate the fuel somehow.  Bubbling is the easiest way.  Connect an air line to the tank suction and let low pressure air in for 10 min or so.  This is to spread the poison around and let it work.

This is nothing new and has nothing to do with the use of Biodiesel.

One thing that seems to have been left out of the article and its comments is the fact that when you use the killer you will need to change your filters fairly often after you put it in. This is to remove all the dead bugs, they will plug your filters faster than the live ones.

So be prepared - have plenty of spare filters.

Ps... One of my favorite places for up to date Biodiesel information is www.thebiodieselnews.com - take a look.
