ABNORMAL OIL PRESSURE/TEMPERATURE
INDICATIONS

RPM - reduce to MINIMUM NECESSARY.

Perform precautionary landing as soon as able.
Oil pressure and temperature problems are usually related with
one affecting the other. Before any drastic action is taken, cross
check other engine instruments and control settings in an attempt
to determine the source of the problem.
High oil temperature is generally a result of loss of oil or
overheating (note CHT). If the situation remains unchecked, oil
pressure usually drops resulting in possible engine damage.
Power should be reduced to the minimum necessary; land as
soon as practical.
Little or no oil pressure is usually caused by a failed pressure
relief valve, pump, loss of oil, high oil temperature or a defective
gauge. A landing should be made as soon as practical using
minimum RPM. Plan a "Precautionary Landing Approach" as
complete engine failure is possible at any time.
High oil pressure is admissible for a short period at cold start.
Should high oil pressure occur in flight reduce power to the
minimum necessary; land as soon as practical.
Zero oil pressure will be indicated if main bus power is removed.
