Attention: TDR Forum Junkies 
As of Nov 1, TCEQ (Texas Commision on Environmental Control) got involved and biodiesel sellers are not allowed to sell blended biodiesel anymore unless they use the additive "Viscon". A B50 blend without the Viscon raises the NOx emmissions by . 5% and TX is freaking out about it. I guess the EPA is on the states back also. Here is a link as to the requirements for the state of TX. http://www.tceq.state.tx.us/assets/public/implementation/air/sip/miscdocs/TxLED-A-00004.pdf
Supposedly Viscon is really expensive and the amounts needed just for a B20 blend could raise the prices of B20 by 15-20 cents a gallon. There are multiple company's trying to get an alternative of Viscon available. This in turn, would lower the prices of Viscon (or equivalent) to where it will only affect the cost by 3-5 cents a gal.
But... All you have to do if you want a blend is fill half way with Dino Diesel then fill the rest up with B100.
DFWBiodiesel sells just B100 now and it's going for $2. 54 while Dino diesel is $2. 45.
