We have a Case 9370 tractor with a Cummins N14 we bought about a year ago. Its rated at about 370 horse. Still had the oil in it that the previous owner used so I'm not real sure what it was. I thought it would have been Case IH #1 15w-40 but the lab said the additive numbers did not seem consistant for that type of oil. 2431 hours on the tractor and 296 hours on the oil. Just started using Polaris Labs and the first report I've gotten back from them.
