re: misconceptions about current oil price
Duicorp.
I'm with Stelep. There is no such word as misperceptions. It does NOT appear in either of my two Oxford dictionaries. Is this a word you have 'coined' or is it a word coined by the Americans, which presumably would appear in the Websters dictionary (which I do not possess). In any case I think the word misconception is a word that better describes the information in your post.
Apart from this slight 'misconception', I found your post very interesting and informative.
I understand that the oil price quotes always relate to Light Sweet Crude, the word sweet, in this context, relates to the LOW sulphur content.
