GAfuels readers already know of the many advantages to using mogas in aircraft approved for its use. Not only does its save them $1.40-$1.50 per gallon compared to avgas, but these pilots are making real progress in reducing lead emissions from general aviation, the only significant consumer of leaded fuel on the planet.
While your bloggers would always recommend obtaining aviation-grade mogas directly from a fuel terminal, and have it delivered and stored in aviation-grade fuel equipment at your airport, in many instances the gasoline obtainable at retail gas stations and marinas is quite suitable for aircraft, provided it has the correct octane (AKI) rating and contains no ethanol. It is absolutely necessary to check each and every batch of fuel obtained from retail sellers of gasoline for the presence of ethanol, regardless how the pump may be labeled. (Fuel contamination is rare, but occurs for every type of fuel, including avgas and Jet-A).
