12.79 OIL SYSTEM
01 GENERAL
There is a separate and independent oil system for each engine with the oil tank in the
nacelle behind the firewall. The oil cooler and automatic oil temperature control are below
the engine accessory compartment.
02 OIL SPECIFICATION
Aero engine oil of grade Aero Shell W100 or Air BP 0100 is required
03 OIL QUANTITY AND CONSUMPTION
The tanks for each engine hold 54 Imperial Gallons. This amount of oil is for long range
and endurance flying, so that for club use a minimum amount has to be specified. Oil in
the tanks at the end of the flight must not be less than 25 Imperial Gallons.
The tanks are to be dipped prior to flight. There are no oil quantity gauges
Consumption for the aircraft should be assessed regularly. Consumption will often differ in
the two engines and will vary according to circumstances with circuit flying producing
relatively high consumption compared to long range cruise.
A consumption of one half Imperial Gallon per engine per hour is to used for flight planning
purposes.
