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.

They are also multi-million dollar aircraft engine companies that recommend
against LOP operation. (Unless you are running a FADEC system).
