Not exactly. That assumes complete heat transfer. The fluids spend a certain time in the respective heat exchangers and the efficiency of heat transfer along with the size of the heat exchanger and the flow rate will dictate the delta temp. Depending on inlet temperature, flow rate and exchanger sizes, the oil can be made to run significantly hotter than the coolant (I can't think of any advantage for the inverse, i.e. coolant hotter than oil). Properly spec'd you can theoretically run optimum oil and coolant temperatures and they're not likely to be equal!
