The correct grade of oil to be used is based on environmental conditions.
If the aircraft is going to be flown into an area that is much warmer or colder than the aircraft is
usually operated in, use a different viscosity of oil.
During operation, if the oil inlet temperatures are near the maximum permitted temperatures, then a
higher viscosity oil can help to decrease the temperatures.
