On this engine the oil is water cooled. The typical water temp is 200 degrees which means there just isn't enough heat transfer between the two given the only slight difference in temp and limited surface area contact.

With an external cooler you would have a much greater temperature differential, resulting in more heat transfer (depending on cooler surface area of course).
