I've never heard of Hess before, we don't have any here. I thought about making biodiesel but became lazy.
I suppose the whole reason for this thread is I'm trying to find which station sells diesel with the most energy per gallon and best cetane level for the normal prices. I use redline DFC which will boost the cetane a few points, but still I'd like to know what I'm buying. I was hoping that there would be a concrete answer, but I suppose most stations get their own fuel from their own distrubutor.
