STC in the works for G100UL
General Aviation News. September 2014
While the government begins its testing of four potential 100LL replacements, George Braly and Tim Roehl of General Aviation Modifications Inc. in Oklahoma just finished up yet another test of their unleaded 100-octane avgas G100UL at Embry-Riddle Aeronautical University.
The fuel underwent flight testing and engine block testing in one of the school’s carbureted 172s.
"No issues were found," Roehl reports. "We just lack a couple of other tests to complete our first STC on the 172."
