Of course it runs "smooth." The question concerns whether it is adequately, efficiently, effectively lubricating the engine. The manufacturer of the Ford does not seem to think so. I am less familiar with the Nissan VQ, but willing to bet that it's not quite the best choice there either, when looking at mfr specs. Loosening Aircooled 911's are a different story, and I have made the mistake in the past of using 5W 30's.
