I agree with most of what the rest of you have said, but just wanted to point out OP has a V6, so the 7.5 and 8 quart discussions do not apply to him. Capacity on the V6 is only 6 quarts and they do use oil. It still shouldn't be overfilled, but it is a different engine design and we do often have to add oil between changes.
Trashmanssd - great story, funny for us, and another good point that if you don't know what you are doing don't work on your car! - at least not without asking someone who does know.
