CAPACITY OF ENGINE SUMP
The engine has a total capacity of 9 quarts, with the oil filter accounting
for approximately 1 quart of that total. The engine oil sump has a
capacity of 8 quarts. The engine must not be operated on less than 5
quarts (as measured by the dipstick). For extended flights, the engine
should be filled to capacity.
OIL AND OIL FILTER CHANGE
After the first 25 hours of operation, drain the engine oil sump and
replace the filter. Refill sump with straight mineral oil and use until a
total of 50 hours has accumulated or oil consumption has stabilized;
then change to ashless dispersant oil. Ashless dispersant oil (and oil
filter) should be changed at time intervals set forth by the engine
manufacturer.
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. Check the
alternator belt in accordance with Maintenance Manual
instructions, and retighten if necessary. A periodic check of
these items during subsequent servicing operations is
recommended.
