Redline is well over 6000 rpm. Running the car well within its designed limits is NOT abuse. It's making use of the performance.
Used to have one of those clover interchanges nearby & I ran my Mazdas through those & had LOADS of fun doing it. Never damaged the car. Run any V-6 Contique through there & you get oil starvation & engine damage. Sounds like a design flaw to me...
Add to that the fact that Ford redesigned the oil pan, what, about 4 times. Ford also has different oil return setup in the heads of the 3L version of what is essentially the SAME block. Looks like they were making changes for some reason. What do you suppose that reason might have been??
C'mon back to the real world please.
