Uhm.... dude. I really don't think anything is going to happen to your car. It just has a little bit of extra oil. I do oil changes on my car and make sure that the oil is full at least to the highest dip-mark. It's over much of the time. It's nothing to worry about. It will probably keep your engine running cooler and give you better gas mileage. And when the car is running the oil level goes down, anyway, because it's filtering through all of the necessary components.
