I know your motor is pretty fresh but you might want to throw a quart of Rislone in it before the next change. Might help keep any contaminants in suspension so they come out with the oil change rather than settle. Won't hurt.
They actually sell a motor flush that I think is kerosene. That’s what the old school mechanics used to flush engines. The faster you get it out the better. Just buy some cheap gallons of oil at Walmart. I think Pennsoil makes their house brand.
