This is an N14 engine in a Case 9370 articulated tractor that we use for a lot of field work. Its kind of had a history or high wear metals for us. I cut my sample interval way back and took a UOA last July and everything seemed pretty good and then took another just a week ago with another 170 hours on it and all my wear metals went way up again. I think the most recent UOA was Shell Rimula oil but I drained that yesterday and refilled with a Service Pro premium. Since we got it I've been using a Fleetguard LF9009 Venturi Combo filter. Unit has about 3600 total hours. I think I'll resample after 250 hours and see what is going on then.
