91 AKI E0 Mogas is available all across the nation. Pure-gas.org currently shows 16,856 sellers of it. We just need airports to add a modest self-service fuel system and find a local fuel supplier to deliver it. U-Fuel makes the best ones. The Mogas does not have to come from an Avgas / Jet-A supplier. Mogas can power 80% of the piston engine fleet with Petersen STCs or all the new engines designed from the start run on it. This is not an either-or option. Keep Avgas too, as is typical at European airports, where pilots have had a Mogas option for many years. This would send a message to those worried about a minuscule amount of lead that we’re really serious. When GAMI, SWIFT or others get their fuel certified, swap the Avgas for it. Every gas station in the country has 3 grades of gasoline, diesel, and often also ethanol-free fuel. Why is this a problem for airports?
