Cantenna oil...the last word?...APPARENTLY NOT

[Paul Dean]

List members -

I have received a number of complaints about the "oil" thread.  I have
allowed this message to pass as, in my opinion, it contains "new"
information.  In general, I think the consensus is that this thread
should "die".

Thanks for your help and understanding.
