There was an article in the local newspaper this morning stating that the city of Boulder Colorado has had 6 vehicles running on 20% bio diesel for 6 months and are planning on having 100 vehicles using bio by the end of 2004.

However, they also HAVE to change fuel filters 2 to 3 times more often than with regular diesel.

It's not worth it to me to pay a premium for fuel and coincidentaly invite a maintenance problem.
