Prior to the first oil change which is recommended at 7500 miles, I check the oil and there was NO oil present on the dip stick…none, not a drop. I had to add 1 3/4 quarts to get it in the accepted range. We took the car for its normal 7500 mile oil change and informed the dealer, upon inspection and oil change they said nothing was wrong with the car. About 2000k miles after that oil change I checked the oil again and again it was well over a quart and 1/2 low. I added enough oil to get the oil level into the accepted range. I made an appointment with the dealer and they looked at the car and said it was 3/4 of a quart low upon arrival and want me to start an oil consumption study. My concern is if this car is using that much oil, its a matter of time before engine failure and what if this happens at speed or when I am on the expressway, it feels like a safety concern to me.
