Thank you, not to let this stray too far off topic but I surmise that the great motivation for direct injection among current automakers is emissions compliance. As far as oil goes a lot of what gets engineered to not come out the tailpipe ends up in the crankcase, which is why I strongly recommend sticking to Subaru's 6000 mile oil change interval for all Subaru direct injection engines if not shortening the interval on your own terms.Found this video at Jalopnik. Real good primer on GDI, I learned a lot. And around the 16 minute mark, he gets into NOACK, so this is somewhat on Kevin's topic.
