Teledyne Continental and (I think) Lycoming have both gone on record
to say that mogas is damaging to their engines. They are certainly
multi-millon dollar aircraft engine companies and have have no
incentive to lie to you.

Yet you, Jay, are an ardent user of mogas. Who do believe: the engine
companies or Usenet?

I'd ask your exhaust system rebuilder to show you the data. I doubt
he really has any and that he is perpetrating yet another aviation
old wives tale. If he does actually have valid data, I'd wager that
a different conclusion could be drawn from it.
