I'm not real sure what you just said.
But I think you're worried about working the engine hard on older oil. 7k miles on even conventional oil isn't a lot. It's more than recommended sure but places like http://www.blackstone-labs.com/
will tell you that as long as a motor is in good tune then even 10k on regular oil is ok.
If you're worried just do a quick compression test. I don't think you'll find anything unless you can physically tell that the engine is running different.
