Personally I wouldnt go over 6K reguardless of what the oil life indicator says. I've seen the inside of a Mercedes engine I owned that went 10K between and it was filthy inside. Loads of build up in the OHC and valley areas. I bought the car with 70K on it and at just over 100K we had a really bad low end tick and had to pull the motor and refreshen it. I was amazed at how dirty the inside of the motor was with oil build up.
Certain brands of oil used to do exactly what you just described. Quaker State used to be the worst for sludge buildup. Today's oils are far superior to what we used to have just 15 years ago.
Just a thought - Ford Motorcraft oil has to come from an oil company because Ford is not in the oil refinement business. Who makes the Motorcraft oil?
Guess I might have to do a internet search and find what I can.
Edit - Just found it. In USA it is ConocoPhillips. In Canada it is Imperial Oil.
ConocoPhillips gas is what I usually run as it has no ethanol here in La.
