I looked under the car, plus the dealer did too (they did first, then I checked myself later). No seepage or leaks from there. Thats why I'm a bit concerned. And it was filled up to the top (max) level on the dipstick when I got the car. I only noticed this maybe about 2 weeks ago. So, unless the dealer changed the oil when my car was being worked on for two weeks (which wasn't noted anywhere on the warranty/service papers), I'm a bit curious to know where the oil's going.
Like I said, I'm getting the oil changed anyway regardless (which I always will do with new cars when they hit 1000 miles or so). So, I'll probably have to wait two or three weeks after that to see if this comes up again...
