At least now, the refinery capacity is stained to the limit
producing auto fuel for the 99.3% of the non-aviation
market. To build a new refinery or a dozen for cars must
come first. Then, if somebody can build a new refinery for
aviation to cover 0.7% of the market...
Back in the 1950's the airlines and military used avgas in
four grades, 80-87, 91-96, 100-130, and 115-145 and jet
fuel. There was a demand for avgas in large quantities for
fighter planes P51s were still being flown by the ANG, the
USAF was flying the EC 121 and some of the cargo was not yet
in C 130s. Airlines flew DC 3 on all the short routes.

82UL won't work well in engines designed for 100-130 or
using turbochargers unless they are derated. Back in WWII
the manuals for the airplanes listed maximum MAP to be used
with different grades of fuel.
