I see lots of stuff available for engine oil coolers. Seems like they may serve a useful purpose but I wonder how often they are really warranted. Mechanically and practically speaking you want your oil to arrive at and maintain an acceptable operating temperature as quickly as possible. But I wonder how many of us really bother to monitor this action.

On my deuce the engine will remain unhooded and will thus reject heat more efficiently than a hooded modern car. During break-in I plan to monitor the oil pool temp in the pan with a hand held thermocouple in order to determine whether or not I need a cooler.

What are ya'lls experiences and opinions here?

Thanks and Regards, Kitz
