This is a UOA from our Hagie 284 self-propelled sprayer. It has a naturally-aspirated Cummins 5.9L engine. It had 2760 hours at time of UOA with 331 hours and 31 months on the oil. Check my math but the last oil change was November of 2007. Oil was Texaco Ursa Super Plus 15w-40. We do not accumulate a lot of hours in a year hence the long duration. If I don't list an element it's a zero.

Engine is run at rated rpm often but does not see a lot of load as it runs the mixers for the sprayer tanks and a hydraulic pump for the hydrostatic drive. I upgraded the filter from an LF3552 to an LF9028. Thinking of increasing the duration to 500-600 hours till the next oil change.
