Thanks for the feedback.

I had always heard that it was "high sulfer" low-tax diesel, and that the dye was there to differentiate it. Now I'm bummed out.

For 6 months, I've been driving 16 miles each way to get Willie Nelson Biodiesel just for the novelty of it and to help support progressive fuel sources. At my truck's consumption rate, that's a gallon each way for me. Not fun right now. I'd rather get a Hardee's (Carl's Jr.) Six Dollar burger with my money. Same price as normal diesel. 20% soy oil, 80% diesel, exhaust smells like burnt beans.
