This isn’t a new idea: Why not run aviation fuel in your classic?
Thanks to its high octane and lack of ethanol, this avgas sounds intriguing.
High Octane: Pump fuel intended for cars and trucks is rated on the Anti-Knock Index, which is the average between the Research Octane N…
My uncle was on the small team of aircraft mechanics at Shannon Airport (Ireland) in the mid 50’s. (A guess at that date) Affiliated with TWA, but whatever landed and needed fixing, you fixed. He would have been about 24 at this time.

only the airport customs guy knew they had access to un-road-taxed fuel, so he regularly dipped their tanks. So they all made brass “top hats” that went into the filler neck and held 2 cups of road fuel.
and it burned real black, so customs guy used to finger swipe the tailpipes, so they all had fishtail exhausts you couldn’t get your finger into, like the Harley guys.
He said his wife told him, “you know the dog wakes up and goes to the door when you are still 3-4 miles away, that car sound is unique..”. Yeah it is!
Avgas is 100LL, that's low lead. I drained 7 gallons of Avgas out of my plane when I bought it, I didn't know that it does not evaporate and thicken like gasoline. I put it in my 350 Chevy truck. OH MY !! Mr. Truck really like it but at $6-7/gallon it was a one time event.
Racecars however ......
