the Castrl GTX is a high detergent motor oil and so are all engine oils ffor diesel motors. Just be aware that if you do use a high detergrnt oil in an old motor the there will usually be carbon build-up behind the rings and once you use the high detergent oil that the rings will lose tension and the engine will be inclined to start burning oil and suffer from blow-by.
