[AT] Was:tractor shopping NOW:fuel

[charliehill]

I did some work last year for a fuel distributor that handles a lot of 
bio-diesel.  What we were doing was insulating and heat tracing the tanks in 
his fuel farm.  If the bio is made from vegetable oil it apparently will 
flow down to a little above freezing with no problem.  If it's made from 
animal fat it will start to gel not much below 50 F.

As far as performance it seems to burn cleaner and stronger than  #2 
according to what his tanker drivers tell me.  However, one of them told me 
he didn't want it in his diesel pickup.  He didn't elaborate.
