12.32.16. Describe the correct oil replenishment procedure for a typical aircraft.Instruments 

Use the dipstick to establish the quantity required.
Take care to ensure that any filler funnels used are clean.
Use the correct grade of oil.
Clean up any oil spilled during the process.

12.32.14(e) . high oil temperature. 

Monitor oil pressure
Open cowl flaps (if fitted)
If high temperature persists land as soon as possible. Particularly if pressure starts to decrease.

12.32.14(d) . low oil temperature; 

Check cowl flaps if fitted. If closing cowl flaps does not raise temp then land as soon as possible.

12.32.14(c) . fluctuating oil pressure; 

12.32.14(b) . high oil pressure; 

Monitor oil temperature and CHT
land as some as possible.

12.32.14(a) . low/zero oil pressure; 

– monitor oil and CHT.
– land as soon as safely possible

12.32.14. State the actions (if any) that the pilot can take to rectify:

12.32.12(e) . high oil temperature. 

high oil temperature can be an indication of:
– insufficient oil
– oil cooler bypass valve stuck open
– inappropriate operation (eg high power low airspeed)
– faulty gauge

12.32.12(d) . low oil temperature; 

low oil temperature is most likely an indication the the oil cooler bypass valve is not working.
Also possibly cowl flaps open at high speed and low power.

12.32.12(c) . fluctuating oil pressure; 

fluctuating oil pressure is probably caused by a sticking pressure relief valve, or a problem with the pump.
