An engine oil change time alarming method of DPF mounted diesel engine is provided to inform the exchange of the engine oil when the fuel emitted in the post injection gets mixed in the engine oil component and the engine oil is diluted over the desired value. An engine oil change time alarming method of DPF mounted diesel engine comprises following steps: a step which determines the driving zone; a step which compares a differential pressure, a regeneration time, and a mileage with a desired value; a step which orders a DPF regeneration when a differential pressure, a regeneration time, and a mileage are bigger than the desired value; a step which performs the post injection after starting a DPF(Diesel Particulate Filter trap) regeneration; a step which compares the oil dilution amount generated by post injection with desired value; and a step which informing the oil change time by turning on and off the oil check lamp.
