I am a happy owner of a 2009 SLK55 AMG. I've had the car for 3 months now and like 3 weeks ago I heard a beeping sound and the message "Add 1 qt. engine oil at next refueling" appeared on the dashboard. I immediately went to an auto parts store, bought 1 qt, of oil and added it. Then I checked the oil level (on the dashboard, no dipstick in my car) and it was OK. Then after a week the same thing happened so I repeated the procedure. Today, a week later, it happened for the third time so I added the oil and took the car to the mechanic. This can't be an oil leak but there is no oil on the floor below the car in my garage -- I can't imagine that is been collected on the pan below the engine because I already added 3 quarts. My mechanic told me that what is happening is very unusual and is now trying to find the problem. He also said "You may want to ask a question on the SLK forum to see if somebody has any idea what it could be, that can save us time". So here I am.. Thank you in advance and enjoy the ride!
