The UOA looks pretty good. You could probably run the PP 8-10k easily in this car, but if you really want to save money, just run regular Pennzoil conventional, or another conventional, and change at 5k - 7.5k miles. The wear results will be every bit as good and possibly better, and the engine will probably outlast the rest of the car either way.
