I have a 07 Suburban (have had Sub's for 15 years), change the oil myself, fill this one with 6 qts and filter, it fills to the top of the hash mark where the full line is, and it doesn't burn oil.

ok,, thanks,,,, 6qt is full,,,, so,,, when my oil level was 1/2 down the hash mark,,,it started this misbehavin' Tuesday,,, still did it with oil added to top of hash mark. the dealer did change the oil, even though it was not ready for that yet,,, Now with oil level 1 inch above hash mark 60# oil pressure at highway speed,,,,,,
This Burb has the same motor has the Impala or something,,,,5.3 ?
Here is a post from another forum, about the 1qt per 1000 mile issue
Subject: Excessive Oil Consumption and/or Blue Exhaust Smoke
2007 Chevrolet Avalanche, Silverado, Suburban, Tahoe
2007 GMC Sierra, Yukon
with 5.3L Engine (RPO LC9 - VIN 3)
Some customers may complain that their vehicle has been using approximately 1 quart of oil every 500-1,000 miles. In most cases, the customer will advise that this did not start until it accumulated approximately 30,000 miles or more.
If the spark plugs have been inspected, the technician would have found signs of oil consumption on one or more spark plugs. If they went on to perform a cylinder leakage test, static compression test, or the lifter and PCV baffle inspection from the latest version of PIP4492, they would find that none of these tests identified the cause of this concern.
In many cases, the engine may have had the rocker cover, cylinder heads, and/or oil control rings replaced only to come back with the same concern.
If this concern is experienced, no repairs should be performed at this time because the cause of this concern is under investigation. This PI will be updated as soon as a procedure is available to help diagnose/repair this concern, which should be available by the end of this month (February 2009).

Apparently nothing has happened with a fix or recall, since my Burb was just at Chevy Shop Wed, ,,, all that was said that it may/will use a qt. every 1000 miles.
