Somehow, in 6 years of flying, I missed the fact that not all light piston
airplanes have oil coolers. Why is this so? What factor determines when an
O-320, for instance, must have an oil cooler? ISTR that the oil does a large
percentage of the cooling in aircraft piston engines. How does the engine
get rid of this heat without an oil cooler?
