The
purpose of the of the heat exchanger is to
cool the oil. Hence, the term "oil cooler".
Like I said, if you want to heat your oil get a pre-heater. That's 100% more effective. Nothing wrong with installing a pre-heater in a sports car either if it's daily driven during the winter (nice comfort item too).
1) Otherwise, it's totally unnecessary. As I started out writing we are using
modern multi grade oil that is perfectly capable of lubricating at lower temp.
2) With regards to oil and water... oil doesn't break down because of condensation. And it will evaporate next time the engine is running anyway. Oil degrades due to too high temp.
3) Next, if people want to heat the oil faster so it takes less time before they can beat on the engine, then that is a false logic too. The oil temp doesn't matter for wheter you can beat on the engine or not as the oil is perfectly capable at lubricating at lower temps (see 1.).
The
whole engine needs to be up to temp. Block, pistons, rings etc. so that is has expanded to the designed tollerances. Having 4 or even 20 deg higher oil temp is not going to aid (much at all) in that.
