oil sample results

just wondering how this oil sample is. I can't get my scanner to work so I'll just write the results down for the last four sample I sent in(they are not for back to back driven miles). Engine is a pre DPF c15 ACERT

dates sampled: 5/10/2014 8/16/2013 4/28/2013
miles on engine: 508512, 498870,438456,417572
miles on oil- 9642,10444,10552,9786
make up added- zero, 1gal, 1gal, 1gal

ETA. I can't get the numbers separated across the screen but they go in order from last sample to first.

 

they are in the correct order. I noticed the numbers are getting better which I thought was odd. The only number that has been getting worse is the Molybdenum levels. Also the iron levels jump around a bit. The engine has 508512 miles on it and I can't remember how many hours are on it. I bought the truck with 280,000 on it and there has been no internal work done to the engine.
