What are you guys talking about!? The guy has a new car. Why in the world would he need to add oil at 9k? Unless partyman is right, the general idea is, if your car ain't burnin oil(which new cars don't) and you don't have an oil leak, there is no need to do anything to your oil except changing it at the recommended interval. Obviosly something is up with the sensor. Why bother playing around with adding oil or being careful not to overfill.. Take the thing to the dealer!
