What about Prestone LowTox?  It is sold at Canadian Tire and is a propylene
glycol (not ethelyne glycol) antifreeze.  Does not explicitly say
phosphate-free, but it does say "Protects all cooling system metals
including aluminum from damaging rust and corrosion."  I'm camping in Canada
and noticed my coolant is low (going to check for leaks, but need to top up
in the meantime).  Anyone use this stuff before?  Is it okay?
