Auto Fuel STC

[maxine_]

Has any of you guys heard about this Auto Fuel STC? What are your thoughts on this?

There isn't an "auto fuel" STC that I am aware (auto fuel includes Ethanol). Petersen, Swift Fuels and GAMI all offer STCs. the one from Petersen, if you aircraft meets requirements, allows the use of non-Ethanol fuel (aka MOGAS). The one from the other two allow the use of their specific fuels, though SwiftFuels also includes future approved fuels, if that happens.
