Again, this is not a problem. Unless there are some other mitigating circumstances causing oil consumption. (Usually covered under warranty.)

If it's so normal, how come my '04 350z didn't burn any oil in the 5 years I owned it? I guess it was a factory freak? How come Nissan is replacing my short block? I guess they enjoy replacing engines unnecessarily?
Sorry about the sarcasm, but a brand new engine (under 20k miles within the first year) should not be consuming 4-5 quarts of oil between oil changes. That, to me, is a serious issue.
