ALL engines start to turn oil dirty as soon as they are started.regardless if it's a diesel or gas engine.
it's the soot in the diesel fuel, it shouldn't affect anything as long as you change the oil at the proper times.
The oil will oxidize and be contaminated with dirt and carbon left over from diesel combustion. The engine oil will start to break down immediately after it is first heated when the engine starts. All paper type fuel, oil, and coolant filters should be changed at 100 hours operating time or once per year, whichever comes first. I record the date and operating hours on the filters with black marker at each change. This makes it easy to determine when the next change is required. Check the coolant conductivity as well as its boiling and freezing temperatures. Change it if either reading is unacceptable.
