Corrosion-
Preventative Oil is installed in the engine at the factory. It is
recommended that this oil be
removedand theoil filterchanged
at 20 hours of engine operation or no later than 25 hours. If oil
consumption has not stabilized by this time, the engine should
be drained and refilled with MIL-L-6082 Mineral Oil. This oil
should be used until oil consumption stabilizes; usually a total of
approximately 50 hours. After oil consumption has stabilized,
MIL-L-22851 Ashless Dispersant Oil should be used.
Drain and replace the engine oil as recommended in HANDL-
lNG, SERVICING AND MAINTENANCE. If operating condi-
tions are unusually dusty or
dirty, more frequent oil changes
may be necessary. Oil changes are more critical during the
break-in period than at any other time.
Use full throttle at recommended rpm for every takeoff and
maintain until at least 400 feet AGL, then reduce as neces-
sary for cruise climb or cruise. Maintain the highest power
recommended for cruise operations during the break-in
period, avoiding altitudes above 8000 feet. Interrupt cruise
power every 30 minutes or so by smoothly advancing to
take-off power settings for about 30 seconds, then returning
to cruise power settings.
