Don't forget to change the oil of the injection pump and the oil in the air filter.
Oil in the injection pump is changed by unscrewing the bolt the red arrow points to and pouring in oil at the top (remove the red cap) until fresh oil comes out. You don't have to remove the bolt completely, it is a banjo bolt.
Mann and Bosch are good brands for filters. MB often uses Mann filters for the filters it sells with the star on it.
