Unleaded Additives

[David Boreham <uunet!inmos.com!davidb@EDDIE.MIT.EDU>]

I'm not sure who posted asking what additives had
been tried in the unleaded engine tests which I
quoted so I'll reply to the list.

The article did not mention any additives by name 
but gave the very strong impression that there
are NO known additives which prevent valve seat
wear completely. I assume that the common additives
which are available over the counter would have been
tested as well as carbonflo.
