I've been reading simialr articles, I have a left field query you or someone may have - concerning oil jargon. I've seen this used a few times and have obviously mis-took the letters for something else - RB. I was reading information on oil and read a chart called an "RBOB crack forward curve" I'm sure there are many that could come up with creative explaination of the term adn reasons why I should be familar and I have discussed these with friends, however at this stage it is a mystery and I would appreciate some help on the - "rb" & "RBOB".
