 I gather that you don't know the name of the expert who made this claim.
 
 In the mean time,  I have checked with some well placed sources inside a
major U.S. avgas refinery,  and that person simply chortled at the claim.
 
 The notion violates the fundamental economics of the way refineries make
money.

 The report is as it was put to me George.
 I don't know why the issue of "who" would be so important to you, but,
 it is simply as I posted, and that is where it must remain.
 You are welcome to email me privately about it if you wish, and
 recommend you do so if you want to continue with it.
 However, there is not much more I can tell you.
 Regards
 Dom Crain
