Algae or asphaltine?

I haul fuel locally in the MN/WI area. All the truck stops get their fuel from mainly one supplier, dosent matter if it pilot/ flying j or TA or more independent smaller truck stop. There is a difference from state to state on the bio. Most of the truck stops like to all use one supplier around here but when the price is right they'll get it from anyone. When people talk about TA being better or pilot fuel being crappier it's kinda a joke because it is the exact same diesel pulled on the same codes. One might add a winter additive but that's seasonal. Here the tanks are all underground.
