What did the wear metals look like on the Rotella? Was it also tested at similar miles? With the same bypass system?
How elevated were your numbers? Did they start before or after the Adrenaline? Could it be HPOP related? Can you post the lab results here?
Again I don't know much about what the numbers mean, but I know people to ask for their opinion on lab results. If you post your test results or links to them, I'll get a fellow 7.3 owner who has been throught the Schaeffer training to explain what he sees in the numbers and how that compares to what the microscope test is telling you. (his opinion won't be biased. He's an engineer first)
