ExxonMobil departs general aviation

ExxonMobil quietly announced its departure from general aviation sales of 100LL and Jet-A in July. According to this AIN Online article, the company will end sales of the fuels to general aviation and dissolve its Avitat FBO network. As documented in this GAfuels article, 100LL sales have been dropping by some 4% annually for years, leading to increasing competitive pressures on the dwindling number of producers remaining in the business.  ExxonMobil plans to continue sales of its aviation fuels for commercial carriers, however.

The GAfuels Blog is written by two private pilots concerned about the future availability of fuels for piston-engine aircraft: Dean Billing, Sisters, Ore., an expert on autogas and ethanol, and Kent Misegades, Cary, N.C., an aerospace engineer, aviation sales rep for U-Fuel, and president of EAA1114.

Autogas experts explain why pump gas is mogas

With the release of its Service Instruction 1070Q on July 16, 2010, Lycoming quietly approved autogas as a fuel for some of its engines — or did they? As news of the company’s about-face after years of advising against the fuel became public, company officials have attempted to explain their confusing stance against a backdrop of thousands of pilots who have happily used autogas in Lycoming engines under STCs from the EAA and Petersen Aviation since 1982 when the fuel first gained approval from the FAA.
