Factory new- you can put synthetic in the first day, though I usually recommend that they leave the factory fill oil in until the first oil drain. Local rebuilt- Run on non-synthetic until satisfied that oil consumption, if any, has leveled off. Remanufactured--ask the remanufacturer, or wait until you are satisfied that it has broken in. As I recall, Jasper said to change the first batch of oil after 500 or 1000 miles, and that synthetic would be fine.
