Initially upon completion of my plane, I used 93 octane mogas. Yes it is very
volatile and I experienced vapor lock problems, due in part to the very hot
temperatures
in Florida. I switched to avgas and haven't had a single vapor lock
problem since. Only recently have I been adding the TCP additive to my avgas,
which is supposed to cut down on the buildup of lead on spark plugs and other
internal parts. With 130 hours under my belt, so far, so good using avgas.

Subject: Rotax 914-avgas or Mogas
Hi All,
I am somewhat interested in this issue. Here in the Mid West of USA you can
generally count on auto gas containing alcohol and other additives. It
appears the additives have a very bad effect on rubber hoes and the like,
and alcohol has the ability to dissolve water which can come out of solution
at cooler altitudes. My other concern is that auto gas is more volatile and
I my be exposing myself to vapor lock.
If I am correct in the above, then I believe that I am left with no choice
but to use AV Gas. I was planning on using an additive to remove the lead.
I'd be interested on anyone's views.
Regards, Paul McAllister
