How is engine oil usually cooled?
- By a fuel/oil cooler.
- By ram air.
- By bleed air.
Explanation from PART66Online
Engine oil is usually cooled in a fuel/oil heat exchanger, where heat passes from the hot oil into the cooler fuel on its way to the burners. This simultaneously cools the oil and warms the fuel, helping prevent fuel icing.

I thought the primary purpose of the fuel/oil heat exchanger was to heat the fuel, and ram air through the oil cooler was the primary oil cooling medium. Any thoughts?

Fuel/oil heat exchanger do two things: cools oil and heat fuel. :)

Checked it out. It would appear the word USUALLY is the key word in the question. I have only worked on the one type of Gas Turbine, and while it has a Fuel Heater/Strainer, the primary oil cooling method for that engine is ram air through an oil cooler.I assumed wrongly that this was a standard practice.
Thanks for your help.
