These are a series of UOAs I've done on a Gehl V270 skid steer we use on our farm. Using either Service Pro or Shell Rimula 15w-40. Using a cellulose Fleetguard LF3369 that is slightly larger than the stock filter. OEM recommended UOA is 250 hours. The first two UOAs, I changed oil and filter at the same time but still using the oil in the lastedst UOA.
Total hours 487, 991, 1740
UOA hours 240, 504, 749
Iron 16, 20, 28
Alum 1, 1, 1
Copp 21, 7, 3
Sili 5, 6, 8
Sod 3, 4, 3
Pot 2, 0, 0
Moly 10,8, 62
Anti 1, 0, 0
Bor 4, 5, 10
Phos 867, 993, 1119
Zinc 1043, 1200, 1315
Fuel >.1, >.1, >.1
Soot >.1, >.1, >.1
Vis 13.9, 13.5, 13.8
TBN 4.44, 4.92, 4.75
Oxid 13, 15, 13
Nitr 17, 19, 8
So the current oil change is a litte past 750 hours. Do you think I could go to 1250 hours and take another sample?
