During break-in periods on new engines, oil
consumption tends to be higher, therefore,
maximum range flights should be avoided and
oil level brought to fuli after each flight during
this period .
Check engine oil quantity before each flight. Under nor-
mai operating conditions, the oil should be changed after
e ach 50 hours of engine operation. More frequent changes
may be required under adverse operating conditions. Use
engine oil as indicated in Consumable Materials in this
section. The engine oil sump capacity is eight quarts. The
normai operating range is six to eight quarts.
