Illinois Airport Adopts Unleaded Avgas
Rochelle Municipal Airport-Koritz Field is the first in the state to offer UL94, which is authorized for use by the FAA in more than 100,000 aircraft.

Rochelle Municipal Airport-Koritz Field is the first in Illinois to offer Swift Fuels’ UL94 unleaded avgas. While not a direct substitute for 100LL, UL94, the only commercially available unleaded aviation gasoline in the U.S., can be used as a drop-in ready replacement in approximately 65 percent of the current piston-powered aircraft fleet, specifically those with engine/airframe requirements that permit 94-or-lower motor-octane fuels.
