I found a flaw in my oil temp instrumentation on last flight and my oil temp is not quite as low as I thought, but still very good.  I got it up to 200 on a full power climb at 69 deg OAT.   

 

What did you climb to, 1500 feet :-)  How about taking off, and climbing at full throttle, and 100 mph to 8000 ft.  Staying below 210 during that test, in the middle of the summer is my criteria for oil cooling.

Hmm, 1500 ft, that would be about 33 seconds of climb for me : )

 Didn't write it down but top of climb was about 4000 ft and oil temp had stabilized.  IAS was very close to 100 mph which is well below my best cooling climb speed of 120 - 130 mph.  I really don't mind using the higher speed after the first 1000 ft so my criteria is not quite as severe as yours. 

 

FWIW, accepting a lower performance from cooling system in climb results in better top end and cruise performance.  Not a law of physics, but in the real world of limited time and money, it's true. 

 

BTW, that was very good advice from Al Gietzen on calibrating the EM2.  I bought that IR temp gauge he suggested and it's the berries, or should I say 'The Bomb' to avoid showing my age.
