that's a Shell Oil secret (oops!!).
Shell Oil, that's a Dutch company, right? No offense to our Forum memmbers.
Just because it is in the U.S. doesn't mean it is ours.
Also, as was previously stated; oil is an international commodity. Unless the Government nationalizes the American oil industry (gosh, I hope not!!!) then we will be at the whim of the "what the market will bear" part of the equation.
Either way, it is giong to be an expensive move for me when I have to drive a moving truck from Oklahoma to Upstate New York this summer. GGGRRRR!
