On Wednesday, General Aviation Modifications Inc. (GAMI) achieved another milestone in developing its unleaded aviation gasoline, G100UL, when it powered a World War II-era bomber, the Douglas A-26 Invader, for the first time.
The aircraft took off from Ada Regional Airport (KADH) in Oklahoma and flew over Lake Atoka during the 60-minute flight. According to GAMI, the warbird’s 2,000 hp Pratt & Whitney R-2800 Double Wasp engine is the most powerful to fly on the G100UL fuel.
“This big-bore radial engine operating at up to 48-inch MP demonstrates the excellent high-octane performance of the G100UL high octane unleaded avgas," GAMI said in a statement. "The ability to successfully operate this engine as such on an unleaded fuel supports the continued operation of these and many other warbirds well into the future.”
