2.
When starting in ambient temperatures of -34°C (-29°F) or below, lubricat-ing oil MIL-L-7808 must be used. It is not advisable to mix MIL-L-23699 or DOD-L-85734 oil with MIL-L-7808 oil.
3.
If the type oil being used is not available, another authorized type oil may be added. When one type oil is mixed with another, it is not necessary to drain the system and re.ll with one type oil. No mixing is allowed for cold temperature operation. For transmissions and gear boxes, when one type of oil is mixed with another, it is not necessary to drain the system and re.ll with one type oil.
4.
For operation below -34°C (-29°F), MIL-H-5606 (NATO Code H-515) shall be used. Mixing MIL-H-5606 with MIL-H-83282 degrades .re-resistant qualities of MIL-H-83282.
5.
Fuel settling time for jet (JP) fuel is 1 hour per foot depth of fuel. Allow the fuel to settle for the prescribed period before any samples are taken (about 4 hours for proper settling).
6.
DOD-L-85734 oil is the preferred oil for use in the main transmission, intermediate gearbox, and tail gearbox, except for cold temperature opera-tion.
7.
DOD-L-85734 oil should not be used in the engines or the auxiliary power unit (APU). If DOD-L-85734 oil is inadvertently added to the engines or APU, the system should be drained and the correct oil added. There is no need to .ush the system.
8.
When changing from MIL-L-7808 or MIL-L-23699 oil to DOD-L-85734 (and vice versa), drain the oil from the system and re.ll with desired oil. There is no need to .ush the system before re.lling.
