I did my second oil change this past weekend and after draining the oil I attempted to install a quick drain valve instead of putting the OEM plug back in, but as I was threading it on it was hitting a bump in the case so I couldn't screw the valve all the way on. So, I had to put the OEM plug back in. It looks like I need a kind of stand-off extension about 3/4 inch or so.
Anyway, after changing the oil (Mobil-1 5W-20) I rotated the tires for a second time as well. Car just past 10K miles and I'm averaging a bit over 37mpg for the entire 10K miles...
