Pennzoil and Quaker State used to use PA crude. One of the only crudes that is paraffin based. They had wax extractors in the refinery process.
My mother used to make candles and she bought 50# of paraffin directly from the QS refinery, back when you could.
Another local refinery had a gas station in the refinery. That one eventually burned for 3 days...
