LUBRICATION AND SERVICING PROCEDURES
Specific servicing information is provided here for items requiring dally
attention. A Servicing Intervals Check List is included to inform the pilot
when to have other items checked and serviced.
DAILY
FUEL TANK FILLERS:
Service after each flight with 100/130 minimum grade fuel. The
capacity of each main tank is 46.4 gallons. The capacity of each
optional auxiliary tank is 19.0 gallons.
FUEL TANK SUMP DRAINS:
Before the first flight of the day and after each refueling, use fuel
sampler cup stored in the map compartment and drain a small amount
of fuel from the quick-drain valve in each fuel sump tank (at bottom
of boom) and in each optional auxiliary fuel tank.
FUEL STRAINERS:
Before the first flight of the day and after each refueling, open fuel
strainer drains (accessible through oil dipstick access doors) for
about four seconds, to clear front and rear fuel strainers of possible
water and sediment. Check that strainer drains are closed after
draining.
OIL FILLERS:
When
preflight check shows low oil level, service with aviation grade
engine oil; SAE 50 above 40°F and SAE 1OW30 or SAE 30 below 40°F.
(Multi-viscosity oil with a range of SAE 1OW30 is recommended for
improved starting in cold weather.) Detergent or dispersant oil, con-
forming to Continental Motors Specification MHS-24A, must be used.
Your Cessna Dealer can supply approved brands of oil.
NOTE
To promote faster ring seating and improved oil control,
your Cessna was delivered from the factory with straight
mineral oil (non-detergent). This "break-in" oil should
be used only for the first 20 to 30 hours of operation, at
which time it must be replaced with detergent oil.

DAILY (Continued)
OIL DIPSTICKS:
Check oil level before each flight. Do not operate on less than 7 quarts
for each engine. To minimize loss of oil through breather, fill to 8
quart level for normal flights of less than 3 hours. For extended flight,
fill to 10 quarts. If optional oil filters are installed, one additional
quart is required for each engine when filter elements are changed.
OXYGEN CYLINDERS (OPT):
Check oxygen
pressure gage in cabin overhead console for anticipated
requirements before each flight. Use filler valve (accessible under
cover plate on top of right wing leading edge at wing root) to refill
cylinders with aviator's breathing oxygen (Spec. No. MIL-O-27210).
