xterra burning oil

[bisonman]

I have a 2002 Xterra that just started blowing a little bit of smoke a couple weeks ago and officially 2000 miles after the warranty expired. I keep up on the oil changes and always put in the correct oil, however I now havea smoking xterra that puts out a tiny bit of blue smoke and in the last week I had to add another quart after my weekly check. Has anyone had this problem or am I the lucky one. Also, what would the next step be?
It is a 4x4 Xterra with 62000 miles
