NOTE :
This airplane was delivered from the factory with a corrosion–preventive
aircraft engine oil. If oil must be added during the first 50 hours, use only
aviation grade straight mineral oil conforming to specification MIL–L–6082.
Capacity of engine sump : 12 U.S. qt (11.3 litres)
Do not operate on less than 6 U.S. qt (5.7 litres). To minimize loss of oil
through breather, fill to 9 U.S. qt (8.5 litres) for normal flights of less
than 3 hours. For extended flights, fill to 12 U.S. qt (11.3 litres). These
quantities refer to oil dipstick level readings. During oil and filter
changes 1.3 additional U.S. qt (1.2 litres) is required for the filter.
