This morning I decided to check the oil level in the car and the oil was passed the full mark by least 1 qt. The oil was changed by the dealer about 1,000 miles ago and I should of checked it then. I called the dealer to see if there was a reason for the overfill and they said it was probably a mistake. I told them it was overfilled by a quart and they said one quart would not cause a problem but two quarts will. I thought this was BS. They told me to bring the car in and they would drain it. This was the first oil change in the car and I'm kicking myself for not checking their work. What kind of damage could the overfill have done?
