I got the same thing when I went in to o'reillys to buy some royal purple for my 370z. I was around 2400 miles and a 1/2 qt low. What they told me was that the nissan z engines break in period is 6k miles. He said the royal purple stuff is thicker than the regular synthetics and won't allow the engine to properly break in if you use it before the 6k mile area. Whether that's true or not I don't know. Thought's anyone?
