8.19 OIL REQUIREMENTS
The oil capacity of the engine is 8 quarts, and the minimum safe quantity
is 2 quarts. It is recommended that the oil be drained and renewed every 50
hours and sooner under unfavorable operating conditions. Full flow cartridge
type oil filters should be replaced each 50 hours of operation. The interval
between oil and oil filter change is not to exceed four (4) months. The
following grades are recommended for the specified temperatures:
MIL-L-22851
Average Ambient MIL-L-6082B Ashless Dispersant
Temperature SAE Grade SAE Grades
All Temperatures -- 15W-50 or 20W-50

Refer to the latest issue of Lycoming Service
Instruction 1014 (Lubricating Oil Recom-
mendations) for further information.
8.21 FUEL SYSTEM
(a) Servicing Fuel System
At every 50-hour inspection, the fuel screens in the strainer, in the
electric fuel pump, and at the carburetor inlet must be cleaned.
(b) Fuel Requirements (AVGAS ONLY)
The minimum aviation grade fuel for the PA-28-161 is 100.
Since the use of lower grades can cause serious engine damage in a
short period of time, the engine warranty is invalidated by the use of
lower octanes.
Whenever 100 or 100LL grade fuel is not available, commercial
grade 100/130 should be used. (See Fuel Grade Comparison Chart).
Refer to the latest issue of Lycoming Service Instruction No. 1070
for additional information.
