Sorry, I checked back, and I got this thread confused with another
similar one that involved discarding old gas with 2-stroke oil mixed
into it, which WILL ruin a catalytic converter, and potentially plug
injectors.

That will not likely cause a problem.
Consider this. Most car manufacturers today believe that a quart of oil
every 1,000 miles is acceptable. (I don't, but that is another issue). In
any case they are talking about burning a quart of engine oil in 1,000 miles
That would be a quart of oil in maybe 40 gallons of gas. Mixing a gallon of
2 cycle mix with say 10 gallons of gas would give you far less oil per
gallon than the manufacturer says is safe, and it is oil designed to burn in
an engine unlike engine oil.
OK, I did this...
1 qt/1000 miles at 25 mpg -- 1 qt/40 gal -- 1/4 gal:40 gal -- 1:160.
My example of 1:32 in a 1:15 dilution tank is 1:15*32 -- 1:480
As you say, that's a factor of three dilution over what would be
considered by many as "normal". It's unlikely there are many vehicles
of significant mileage that don't use close to that per tankful
although, of course, not all of it is burned.
So, I'm still comfortable that such a dilution will not be the cause of
immediate failure of a catalytic converter. I would still try to use
any old 2-cycle prepared fuel by diluting it in a 2-cycle engine, but
think Red Cloud's concern is way overblown.
