What is the maximum oil temperature?

Oil temperature limits are set by the engine manufacturer to keep lubrication effective and prevent oil from breaking down. The maximum allowable oil temperature for this engine is 245°F. That value is the redline you don’t want to exceed, because when oil gets hotter than its rated limit, its viscosity drops and it can’t form a proper lubricating film. That leads to accelerated wear, possible bearing damage, and even engine problems if overheating continues. In flight, if the oil temperature nears this limit, you should take cooling steps (increase airspeed, ensure the oil cooler is functioning, reduce power as needed) and verify oil level and condition. The other numbers are either below the limit or above it and do not represent the engine’s specified maximum.
