Cessna 172 R&S
(FAA-Version)
OIL PRESSURE TOO LOW (< 2.3 BAR IN CRUISE (YELLOW
RANGE) OR < 1.2 BAR AT IDLE (RED RANGE)):

(2) Check oil temperature: If the oil temperature is high or near
operating limits,
i) Land as soon as possible
ii) Be prepared for an emergency landing
iii) Expect an engine failure

Note:
(3) Increase the climbing airspeed, reduce angle of climb
(4) Reduce power, if the engine temperatures approache the
red range
OIL TEMPERATURE "OT" TOO HIGH (RED RANGE):
(1) Increase airspeed and reduce power as quickly as possible
(2) Check oil pressure: if the oil pressure is lower than normal
(< 2.3 bar in cruise or < 1.2 bar at idle),
i) Land as soon as possible
ii) Be prepared for an emergency landing
iii) Expect an engine failure
(3) If the oil pressure is in the normal range:
