This is probably going to sound really stupid, but I checked my oil before driving the Boss (cold) and it was right above the top hole. Put about 120 highway miles on it and when I got home I checked the oil and it was higher, above the top fill line and another 1/3 inch. I checked it 4 times because it seemed odd, waiting a minute or so between each one. I have never seen this happen before, at least not enough to notice. Last time I drove it, when I checked it hot when I got home, it was right at the top fill line. It used to burn a lot of oil, 5 quarts in the first 2700 miles, but has not burned a significant amount in the last 300 since I changed the oil. It has sat for about a month other than one trip to the dealership to have them look at something (which was why it was sitting, hadn't had time to bring it in).
I'm stumped. I have never seen this in another car, but maybe one of you guys has.
