Best bet is to mix 76 leaded super with a good no-lead regular.  The
octane of the mix is higher than either alone.  (Lead has a non linear
octane boost on the gas, no-lead has a higher quality stock.  The dilution
of the lead has low effect, the boost of octane of the no-lead has a
high effect).

There was a suggestion earlier to use Naphthalene Moth Balls for an
octane booster.  I tried some in my car.  Seemed to run fine.  But
my car will eat any gas, so I can't attest to the octane boost part.
You could always try them and report to the net ...  (20 Moth Balls
per tank or so; and don't use the para-dichlorobenzene ones)
