Yes, at least until they knew better or they I knew
someone with actual experience who could tell them
different.  Better to look like a ignoramus asking
ridiculous questions, than have a stinking airplane
with an engine that won't run.  I posted the issues
here, 'cause I thought there might be at least one
or two who've flown with mogas a few times 8*)

I keep hearing nebulous concerns about mixing mogas
with composite tanks like the Delta has (alcohol
will attack the epoxy, etc), but it doesn't seem
like anyone has any solid data.  Just innuendo.
That is why I was talking with an epoxy expert.  I
appreciate Perry's data point and 5yrs of
experience.  Perry, what epoxy did you use for the
tanks, and do you take any special precautions when
fueling up?

The other two 'issues' were out of the blue.  The
Cherokee I trained in used mogas.  I never noted
excessive smell, and my flight instructor said it
kept his plugs clean.  The issue with stale gas has
some credence due to my observation of some
ultralighter who religiously dump 30day old
two-stroke mixes.  What I didn't get was how 100LL
smelled any better or stored any longer.  Both
issues appear to be red herrings

I will admit that there comes a time when old gas will stink  In fact that is a good indicator of whether the stuff is suitable for using.  If it still smells good, I use it.   The corollary to this rule is that if your gas stinks, you are not flying often enough :>)
