"It's not so much an oil shortage but more of an issue with refinery capability."
And you believe that?
Crude is heading for 100 dollars....what does that have to do with the ability to process it?
IMO...Synthetic's have replaced a big chunk of lubricating industry.
I don't put into the refining capability at all.
I might put into a short supply of crude....such as, the middle east conflict protracting the problem.
