BREAK-IN
ENGINE OIL
I
The
new
airplane
is
delivered
with
corrosion
preventive
compound
(3,
Chart
3)
in
the
engine.
It
is
recommended that
this
corrosion
preventive
compound
be
changed
at
20
to
25
hours
of
engine
operation.
If
the corrosion
preventive
compound
is
not
removed
at
the
proper
time,
varnish
may
form
in
the
engine.
Oil
conforming
to
MIL-L-6082
may
be
added
to
the
corrosion
preventive
compound
as
necessary.
After
removing
the corrosion
preventive compound,
refill
and
use
oil
(6,
Chart
3)
until oil
consumption
has
stabilized. After
oil
consumption
has
stabilized,
an
ashless
dispersant
oil,
complying
with
Continental
Motors’
Specification
MHS-24B
and
MIL-L-22851,
must
be used. For
I
suitable
engine
oil,
refer
to
(2,
Chart
3).
NOTE:
A 75%
power
setting
is
recommended
during
the
break-in
period.
Avoid
overcooling
caused
by long
power-off
and/or
rapid
descent.
OIL
SYSTEM
NOTE: After
engine
break-in
period
and
at
each oil
change
thereafter,
use
only
detergent
oil
meeting
Teledyne
Continental
Motors
Specification
MHS-24B
for all
Continental
engines.
The break-in oil
in
the
engine
when
I
the
airplane
is
delivered
from
the
factory
is
a
corrosion
preventive
compound
(3,
Chart
3)
and
should be
changed
after
20
to
25 hours
of
engine
operation.
Replace
with oil
(6,
Chart
3),
which
is
used until
oil
consumption
stabilizes.
The
engines
are
equipped
with
a
wet
sump,
pressure
type,
oil
system.
Each
engine
sump
has
a
capacity
of
12
quarts.
Servicing
the
oil
system
is
provided
through
access
doors
in the
engine
cowling.
A
calibrated
dip
stick
adjacent
to
the
filler
cap
on
TC serials
and attached
to
the filler
cap
on
TE
and
TH
serials indicates
the
oil
level. Due
to
the
canted
position
of
the
engines,
the
dip
sticks
are
calibrated
for
either
right
or
left
engines
and
are
not
interchangeable.
Under
normal
operating
conditions,
the
recommended
number
of
operating
hours
between oil
changes
on
all
TC
serials is 25
hours.
A
100
hour oil
change
interval is
recommended
for ail TE and TH
serials
provided
the
oil
filter
element
is
changed
at
each
oil
change.
When
operating
under adverse weather conditions
or
continuous
high
power
I
settings,
the
oil
should
be
changed
more
frequently. Torque disposable

inch-pounds.
Engines
manufactured
after
April,
1975,
used
on
the
TE
and
TH
serials,
use
an
oil
filter
which has
a
by-pass
valve
designed
into
it
and
an
oil
filter
adapter
with
the
by-pass
valve
eliminated.
The
later
oil
filters
(P/N
641583
and
P/N
641584)
are
a
gold
color.
CA
UTION:
The
earlier
oil
filters
(P/N
632399
and
P/N
637584)
are
a
black color
and
MUS
T
NOT
be
used
on
engines
manufactured
after
April,
1975,
since the later
gold
oil filter
has
an
adapter
without the
by-pass
valve.
However,
the
gold
oil filter
(P/N
641583
and
P/N
641584)
can
be
used
on
either
oil
filter
adapters
without
any
modifications.
