Mike, I take it your car doesn't have the FSS indicator? I run this same factory-speced oil in our car and change it out around 10k miles. I've performed UOA on the past two changes. The results have been virtually faultless. Based upon what I've found via UOA, I'm going to start changing the oil no later than 10k miles regardless of the prediction made by FSS.
You might wish to change earlier with a 4 cylinder engine. As hatterasguy mentions, it's nothing but guesswork changing the oil with short intervals.
Take care.
