I would like to see how the results come back.

I have seen the internals on our class 8 trucks at work. They are nice and clean with no sludge. We only change the oil every 85000 miles. We use Mobil Delvac 1 . We do a filter change and chassis grease every 15000 miles. A fleet of 33 trucks that runs just over 3.2 million miles a year, and we have never seen a oil related failure.
