HANDLING, SERVICE & MAINTENANCE
The
introduction
of
alcohol
or
DiEGME compound into
the
fuel
provides
two
distinct
effects: (1) it absorbs the dissolved water
from
the gasoline and (2) alcohol has a freezing temperature
depressant
effect.
NOTE
When
using
fuel additives,
it
must be remembered that
the
final goal is to
obtain
a
correct fuello-additive ratio
in
the
tank, and not just with fuel coming out
of the
refueling
nozzle.
For
example,
adding
15
gallons
of
correctly
proportioned
fuel
to
a
tank which contains
20
gallons
of
untreated
fuel
will
result
in a
lower-than-acceptable
concentration level
to the 35
gallons
of
fuel which
now
reside
in
the
tank.
Alcohol, if
used,
is
to
be blended with the fuel in a
concentration
of
1o/"
by
volume. Concentrations greater
than
1o/o
are
not
recommended
since
they can
be
detrimentalto fueltank
materials.
The
manner
in
which
the
alcohol
is
added
to
the fuel
is
significant because alcohol
is
most effective when
it
is
completely
dissolved
in the
fuel.
To
ensure proper mixing,
the
following
is
recommended:
1.
For best
results,
the alcohol should be added during
the
fueling operation
by
pouring
the
alcohol directly
on
the
fuel stream
issuing
from the
fueling
nozzle.
2.
An alternate method that may be used is to premix
the
complete alcohol dosage with some
fuel in
a
separate
clean container (approximately 2-3 gallon capacity)
and
then
transferring
this mixture to the tank
prior
to the
fuel
operation.
