I can check to see what the Cummins recommends for the 5.9 once I get back to the shop on Monday. But the sample doesn't look bad at all. Does the analysis company ask for the type of oil used. You can try the analysis company that we use at Cummins. Not sure the price but you can pick it up at our parts dept.

Your UOA is excellent, the only thing I would do different is extend service interval to 7,500, then change, resample the oil and possibly extend even further from there. You are waisting you time and money changing it out at 5k. JMO
