Motor oil question

Does any one know how to tell if a motor oil is diesel rated by reading the label on the side? i think it is SJ something but am not sure. also i currently use 15-40 in my engine and wanted to go up to 20-50 because of high miles, i live in CA and have 301000mi on the engine any suggestions on the oil, normal driving conditions.
