Oil Guzzler??

I swear my car is a Oil guzzler not a gas guzzler
... so.. My C350 has 6000k on it since I bought it mid september and my oil has gone to the low levels of the dipstick twice already! I put oil in there to refill it the first time, and the second time I took it to the dealer... and they said just put a quart in IT, and their explanation was that it is "cold" and it's a new car so it burns more oil for now.... sounds kinda fishy to me.. anyone have the same issue or more info on it? thanks in advance!
