capacity of the
Teledyne
Continental
engines
is
8
quarts
per

with
a
rninimum
safe
quantity
of 3
quarts
per
engine.
It is
recom-
mended
that
oil
be
added
if
the
quantity falls
to
6
quarts.
It is
recommended
that
engine oil be
drained
and
renewed
every
100 hours,
or
sooner
under
unfavorable
conditions.
Full
flow
cartridge
type
oil
filters
should
be

FUEL
SYSTEM
(a)
Servicing
Fuel System
The
fuel
screens
in
the
strainers
require
cleaning
at
50
hour
or
90 day
intervals,
whichever
occurs
first.
The fuel
gascolator
strainers
are
located
in
the
wing
between
the
fuel
selector
valves
and
tfie auxiliary
pumps
in the
nacelles.
The
fuel injector
screen
is
located
in the
housing
where
the
fuel inlet
line
connects
to
the
injector.
This
screen
should
be
cleaned
every
50
hours
of
operation.
(b)
Fuel
Requirements
The
minimum
aviation
grade fuel
for
the
Seneca III
is
100.
Since
the
use
of
lower
grades
can cause
serious
engine
damage
in
a
short
period
of
time, the
engine
warranty
is
invalidated
by the
use
of
lower
octanes.
Whenever
100
or
100LL
grade
fuel
is
not
available,
commercial
grade
100/ 130
should be
used.
(See
Fuel Grade
Comparison
Chart.)

to
the
latest
