4.1.1
Standard
car
or
RV
antifreeze
is
NOT
recommended
Standard
car
or
RV
antifreeze
consists
of
propylene
glycol
or
ethylene
glycol,
which
have
a
specific
gravity
>1.
This
allows
a
layer
of
water
to
sit
on
top
of
the
antifreeze
that
may
freeze
and
form
an
ice
cap
that
prevents
snowfall
from
being
dissolved
into
the
solution.
Mixing
the
antifreeze
with
ethanol
solves
the
specific
gravity
issue
and
prevents
the
ice
cap.
PGE
is
also
more
environmentally
friendly.
