Below is an entry I made on my mailing list group. It contains interesting info sent to me via email 'supposedly' originating from a refinery worker. Might be urban legend, but seems some elements might be truth. And probably contains enough thoughts to help with the cost of gas.
The first tip is a ringer, must advise.
