CESSNA AIRCRAFT COMPANY FOR TRAINING USE ONLY
MODEL 152 8-10
CAPACITY OF ENGINE SUMP – 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 oil
dipstick level readings. During oil and oil filter changes, one additional quart is required when the filter
is changed.
OIL AND OIL FILTER CHANGE –
After the first 25 hours of operation, drain the engine oil sump and oil cooler 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 oil cooler and clean the oil
pressure screen each 50 hours thereafter.
On airplanes which have an oil filter; after the first 50 hours, change to dispersant oil and change the
filter. Repeat every 100 hours thereafter.
Change engine oil at least every 6 months even though less than the recommended hours have
accumulated. Reduce intervals for prolonged 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, evidence 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, chafing, burning,
defective insulation, loose or broken terminals, heat deterioration, and
corroded terminals. A periodic check of these items during subsequent
servicing operations is recommended.
