The basic principle of heat exchangers seems to be clear to everyone, including bongodriver.

But:
- basic principles of heat exchangers don't fully explain general aircraft engine oil temperatures
- general aircraft engine oil temperature characteristics don't fully explain Spitfire specific oil temperatures
- detailed Spitfire oil temperature info won't change a thing in game, because development is dead
