what kind of tractor? how many hours??
so was it high Ni, Cu, or Ag (or all)? How high? I think there is Lead in there too.
I think 7500 miles is the normal interval for the PSD (and 5K for severe)? I can't remember since I got rid of mine almost 4 years ago.
Also what or how high is little bearing wear?
Do you do alot of cold starts? short runs?
Last one, unless you have high soot, TAN, Si (dirt), fuel, water I think the oil is fine. Do you have an coolant in it?
I know there is a paper from the SAE about bearing wear. It came down to high-temperature high-shear-rate (HTHS) rating) viscosity and oil elasticity. Paper is #980702, 'Properties of Engine Bearings Lubricated with Low HTHS Viscosity Oil'. I can get it at work.
What are delvac normal HTHS, cold crank and Kinematic Viscosity? I am sure I posted this before.
Amsoil 15w-40 is really good and cheap! I know I always had grat numbers with it doing long drain (11 to 12K miles). I think the oils is like $20 per gallon.

they told me air and oil filtration looked good, No antifreeze or fuel.
TBN was 9. Lead was 9 from an average of 8, silicon was 16 from an average of 14, zinc and silver look normal. sustained vis was 76.8 from a value of 68-78. fuel was <o.5 should be <2.0.
