I thought it would be good to show some trending from Shell Rotella 15w40 through two changes on Schaeffer Supreme 7000 15w40. This is a ITC 5000 Dump Truck. about 300-350 miles a day (short trips)

I'm curious how it's possible on that first analysis, to have an oxidation of zero?

Also, it's interesting to see more moly on the very first change with Schaeffers. I would have thought it would be less on the first interval, due to the moly plating up, then on the second interval it would show more moly.

Patman, It had to be a mistake,I think

The moly was a mistake on my part, it was 155 not 73
Thank you for pointing that out! I will edit the post. [Duh!]

It's yet another great analysis for Schaeffers! I'm getting more and more excited about
putting this oil in my car. I've only got 1645 miles to go! [Big Grin]

Those are very good numbers. I would have liked to see the Shell run for 15,000 + miles to see what it would have looked like. At 9,800 miles the Shell looked very good also.
