The temperatures mentioned in the table are the ambient temperatures
at the time when the engine is started.
However, if the running temperatures are much higher than the starting
temperatures a compromise must be struck and a higher viscosity oil used ,
providing starting is satisfactory. Multi grade oils overcome the problem,
provided they have a suitable specification .
The engines must be run on heavy duty lubricating oils, meeting the
requirements of API CC.DEF2101D, MIL-L-2104B or MILL-L-46152A/B
