The oil that comes with the car may as well have sand in it. After my initial oil change at 1315 miles the car ran much, MUCH smoother. The replacement oil was Nissan Ester Oil though. I'll switch to synthetic eventually, but I don't think the reduction in engine NVH after the initial oil change can be attributed to the type of replacement oil.
