The pros and cons of using ethanol blends in light aircraft may seem like a new issue, but this article that appeared in the June 1935 issue of “Popular Aviation” expresses many of the same concerns shared by your bloggers.

While we are not categorically in opposition to ethanol’s use as an aviation fuel, its presence in fuels today renders thousands of autogas STCs worthless and removes an option that could power 80% of the current fleet of piston-engine aircraft. Thanks to the EAA’s Paul Poberezny for this historical perspective of an important topic affecting us today.

The GAfuels Blog is written by three private pilots concerned about the future availability of fuels for piston-engine aircraft. They are:

• Dean Billing (Sisters, Ore.) – an expert on autogas and ethanol
• Kent Misegades (Cary, N.C.) – an aerospace engineer and aviation journalist
• Todd Petersen (Minden, Neb.) – former aerial applicator and owner of more than 150 Mogas STCs for aircraft
