Well hate to say it, but I was the guy that changed the oil and did this.
Like I said, I had it all warmed up and got a low reading so I just put the rest of the 7th quart in. And then thinking about it, the car wasn't level when I drained so there could be some leftover to add to that amount as well. (dumb mistake!)
I just did this yesterday, so the CE light coming on after just a couple miles seems awfully suspect. The fact that I did it yesterday also means that I hate to do another change: especially since I use Mobil One.
But sounds like I better do something about it, this may get messy.
