alt Hacker NewsOne of my favorite tractors was the old Oil Pull's which were designed for oil in the radiator. (they were a gas engine, but designed to run on "tractor fuel" which is closer to diesel than gasoline - in order to work the engine had to be very hot)

It's of course possible to design engines to be oil cooled, though water-glycol tends to be preferred due to about twice the specific heat capacity, meaning smaller coolant channels, radiators, and fans are required.
