Auto Gas STC

[AggieMike88]

When someone acquires an STC to burn MoGas, is anything actually changed on the aircraft (tank, plumbing, engine wise)? Or is it mostly a paperwork update?

OK, so I'll bring a stupid question to the table. WHere in the USA can you still get real gasoline?

A list of gas stations carrying ethanol-free gas in the U.S. and Canada:

A list of airports:

Several other online resources and groups that get access to it:

An Avweb podcast with Ken Misegades on this subject, which provided the seeds to finding the above and contains other suggestions:

That's good. Because they haven't.

Violation of a mandate is met by punishment. Conformance to a mandate is met with reward or no punishment. The reality of EISA 2007 is that it appears to be semantically close to being a mandate that the difference is not worth arguing over. There is this view: http://e0pc.com/newreality.php

This list is not complete. There are dozens of mogas sites in Wichita alone that are not on this list.

Those sites appear to have ways for you to enter that information into their lists. If you are able and willing, I'm sure everyone using those sites would appreciate the updates.

Almost every larger town has a place that automotive racers get their fuel that is almost always ethanol free. Ask at the local track.

The Exxon station a mile from my place (Dexter, OR) is selling ethanol-free premium gas for $5.20/gallon. No other ethanol-free grades available there.
A few miles away at Creswell airport 100LL is being sold for $5.76/gallon. Jet-A is going for $4.54/gallon

While that Exxon has always had higher prices than average for this area, the price difference in this case doesn't seem terribly large.

Now if there were a cheap way to engineer a Jet-A STC for the Cessnas I rent....
