LUBRICATION AND SERVICING
PROCEDURES
'--.-- i
Specific servicing information is provided here for items requiring daily
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 80/87 minimum gTade fuel. The capac-
ity of each wing tank is 13 gallons for standard fuel tanks, 19 gallons
for optional long range tanks.
FUEL STRAINER:
On
the first flight of the day and after each refueling, pull out fuel
strainer drain knob (located just inside cowl access door) for about
four seconds, to clear fuel strainer of possible water and sediment.
Release drain knob, then check that strainer drain is closed after
draining.
OIL FILLER:
When preflight check shows low oil level, service with aviation grade
engine oil; SAE 40 above 40°F and SAE 10W30 or SAE 20 below 40 ° F.
(Multi-viscosity oil with a range of SAE 10W30 is recommended for
improved starting in cold weather.) Detergent or dispersant oil, con-
forming to Continental Motors Specification MHS-24, 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.
OIL DIPSTICK:
4-6
Check oil level before each flight. 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. If optional oil filter is installed, one additional
quart is required when the filter element is changed.
