I worked on a project plane for 5 years with 10 gallons of 100LL in each tank the whole time. When the plane was returned to service, I used the fuel to do ground runs and 2 hours of flight. The fuel looked good as new and there were no issues with the fuel system or engine running. Yes, 100LL is extremely more stable than auto gas.

I ran a generator on 100LL. After 10-15 gallons, it started to misfire under high load. Run a few gallons of regular car gas and it cleared right up. My theory is the lead was causing issues with the spark plug. The regular gasoline allowed the lead to burn off and clear the misfire.

Engine tolerated 100LL in small doses, but wasn't happy about it after a while. If I had 20 gallons to dispose of, I'd alternate fillups with regular gas to keep things from fowling up.

Default Race track

Second anything without a CAT.
Take it to a race track. They will fight over it. Many teams would buy 100LL and bring 5gal tanks. Race cars and motorcycles.

Lawn Mower. Friend's old motorcycle. 1969 Mustang convertible.

Or anything without a catalytic converter that will eat leaded fuel. 100LL is pretty darn stable and lasts a long time. I'd worry more about contamination than age when it comes to putting it into a non-airplane engine.
