I think people are noticing it more with extended drains. If you have minor oil consumption, you probably wouldn't notice it in a 3000 mile oil change. It may be a bit low but nothing noticeable. Extend that to 10K and you'll notice it.
That's why Subaru backed off on the 7500 mile oil change on the F-series engines. People were noticing a lot more oil consumption and running their engine dry. I would have liked to be able to do 7500 in my Forester!
