However, whenever I've been stuck, as at a dirt road cross roads in Nevada,
and ONLY 85 AKI was available, the waterboxer did not knock, and mileage was
as usual (about 19.5 mpg).  On that particular 4800 mile trip, however, my
mileage varied dramatically, from 17.4 to 23.5 mpg.  I assumed conditions
(wind, temperature, grade) made the difference.

  For general information, the gasoline in Mexico has a very low octane,
especially in the Nova grade.  In the Baja there are many times when only
Nova is available.

  I've ridden dirtbikes down there often, bikes that Nova really runs BAD
in.  I took a good supply of octane booster along for those times when I was
left without the choice to use Magna Sin...or whatever the might call their
Premium fuel now.  The Premium fuel ran about like US Regular...Nova pinged
like crazy, always.
