-- 6
Quarts.
Do
not
operate
on
less
than
4
quarts.
To
minimize
loss
of
oil
through
breather,
fill
to
5
quart
level
for
normal
flights
of
less
than
3
hours.
For
extended
flight,
fill
to
6
quarts.
These
quantities
refer
to

and
oil
filter
changes,
one
additional

required
when
the

OIL
AND
OIL
FILTER
CHANGE
--
After
the
first
25
hours
of
operation,
drain
the
engine
oil
sump
and
clean
the
oil
pressure
screen.
If
an
oil
filter
is
installed,
change
the
filter
at
this
time.
Refill
sump
with
straight
mineral
oil
and
use
until
a
total
of
50
hours
has
accumulated
or
oil
consumption
has
stabilized;
then
change
to
dispersant
oil.
On
airplanes
not
equipped
with
an
oil
filter,
drain
the
engine
oil
sump
and
clean
the
oil
pressure
screen
each
50
hours
thereafter.
On
airplanes
which
have
an
oil
filter,
drain
the
engine
oil
sump
and
change
the
oil
filter
again
at
the
first
50
hours;
thereafter,
the
oil
and
filter
change
interval
may
be
extended
to
100-hour
intervals.
Change
engine
oil
at
least
every
6
months
even
though
less
than
the
recommended
hours
have
accumulated.
Reduce
intervals
for
pro-
longed
operation
in
dusty
areas,
cold
climates,
or
when
short
flights
and
long
idle
periods
result
in
sludging
conditions.
NOTE
During
the
first
25-hour
oil
and
filter
change,
a
general
inspection
of
the
overall
engine
compartment
is
required.
Items
which
are
not
normally
checked
during
a
preflight
inspection
should
be
given
special
attention.
Hoses,
metal
lines
and
fittings
should
be
inspected
for
signs
of
oil
and
fuel
leaks,
and
checked
for
abrasions,
chafing,
security,
proper
routing
and
support,
and
evidence
of
deterioration.
Inspect
the
intake
and
exhaust
systems
for
cracks,
evi-
dence
of
leakage,
and
security
of
attachment.
Engine
controls
and
linkages
should
be
checked
for
freedom
of
movement
through
their
full
range,
security
of
attachment
and
evidence
of
wear.
Inspect
wiring
for
security.
