A Paul Bertorelli interview of Paul Millner regarding details on the production side of Avgas, G100UL, etc.: https://www.avweb.com/multimedia/paul-millner-on-avgas-market-realities/
Very interesting discussion - -fuel blend from 1943 - fighter fuel - - that should calm the turbo/supercharged crowd nicely.
Do the Reno guys use this fuel in the racers?
.....One thing - he stated that this is the same formulation as they presented to FAA in 1994 (?) but there was a reason FAA would not approve for the industry. I did not quite understand the implications of that statement and how it would affect us. Can anyone provide some illlumination?

1:44 into the Paul Milner interview, Xylenes in G100UL vs. Tolulene of Avgas.
I think that answers Bill's question best.

I think that answers Bill's question best. Watch to 3:50 in for the octane enhancer, which shows up in the patent.
The FAA wanted, for years, No Lead Avgas that looked just like TEL/100LL without the lead, which did not catch on as it would not support all existing engines.

"Selected aromatic amines, such as m-toluidine, may also be added to increase motor octane number"
