A car that doesn't burn oil doesn't exist. All cars will burn oil to some extent. 1 quart every 1000miles is a given max though. Research has shown me that oil MUST get past the rings, as a sign that wear is being prevented. Oil levels that don't change is an illusion. As the oil is burned off, it is replaced by combustion byproducts and water. This gives the illusion of no oil consumption. If found excessive though keep an eye open for leaks and any blue smoke. If none of these conditions exist, don;t worry too much about it. My car burs at least a quart every oil 3000miles. Mostly evident though after a highway run where the oil gets hot enough to boil off the water and crap and show my true oil level.
