How long do "these markets" last?

Raised elsewhere - there are some who believe leaded avgas is going to be more restricted in the coming months. That would have a pretty severe impact on airplane resale, yes?

Depends on the plane. Many of our planes are eligible to purchase the Mogas STC which allows us to burn 87 octane gas with no alcohol. I have looked into it before and did not do it because of the hassle involved to purchase away from the airport, store it, keep it water free, and dispense it in the plane. If 100LL becomes unavailable, ethanol free Mogas is available about three miles from the airport. It will mean a tank and pump in my pickup. Maybe if it gets to that point they will sell Mogas on the field.

Yeah, but what about all the other airplanes that aren't certified to use mogas? Their effectiveness will be impaired, right?

 

[MBDiagMan]

I never said they didn’t. I only commented about the planes that are eligible for the STC. If some of them use Mogas, maybe there will be enough to go around for the planes that need it.

So as prices of Avgas go up, the prices of planes go down? (Mooney's excepted and I have worked on plenty of them so I would not own one).

generally yes. There hasn't been a real uptick in the pressure point of 100LL since around 2012. None of that had anything to do with fears of 100LL discountinuation though. Avgas ain't going anywhere. This notion that the market will cease 100LL production absent a substitute product of equal octane performance is unfounded. I'm no fan of TEL but even I'll take that bet every day and twice on Sunday. I have gripes and concerns about the sustainability of this hobby, but the availability of 100 octane in the post-TEL era is not one of them.
