c230 oil consumption??

[wesplank]

Is it normal for a 2003 c230 to use oil. My computer tells me to add 1qt of oil to reach maximum level. No leaks, car is drivin short distances, very little highway driving. My car has 9000 mile since the last oil change. It was full then. If its normal where is the oil going. I have a difficult time believing that a mercedes with 53000 should use any oil.
