In May 1927, Charles Lindbergh launched from Roosevelt Field on Long Island, New York. Thirty-three and a half hours later he, in an aviation first, landed in Paris. In May 2017, Espen Jakobsen took off from the Purdue University airport in Lafayette, Indiana, en route to Zweibrücken, Germany, in a 1950 Beechcraft Bonanza. He landed 33 and a half hours later. The Jakobsen flight was also an aviation first, because the airplane’s six-cylinder Continental E-225 engine burned only UL94 unleaded avgas from Swift Fuels.
Swift Fuels is the only company selling unleaded avgas in the United States and has expanded its distribution network across the country.
I’d had the tanks filled the previous evening with “94UL”—an unleaded product from Swift Fuels that is chemically identical to 100LL without tetraethyl lead. The new Swift fuel is FAA-approved for engines that can operate on 80/87-octane aviation fuel, or the 91-octane fuel that the 160-horsepower Lycoming IO-320 in my Experimental-category RV-3B requires.
Swift Fuels is once again creating a buzz in the general aviation world with the announcement that it will produce 94 MON avgas. The unleaded fuel alternative will work in light sport aircraft that have Rotax engines, aircraft that have a supplemental type certificate for autogas, and airplanes that can run on avgas (engine rated 94 motor-octane-number or lower).
