Don't you still have the 5 year 100k mile drivetrain warranty? Id look at the harness by the exhaust if you haven't already. That's known to chafe on the diesel gladiators.
Don't talk about my underwear. This was my first and only with stp prior to that was QS and pp. Fuel dilution is on the report. This doesn't look like a bad report to me.
No, your problem is you're looking at OEM when there are better aftermarket options. There's a whole thread @biodiesel put together on oil and filter options in the 3.0 forum.
