Second leg done. This time I averaged a little over 66mpg over 884 miles, averaging 65mph according to the scangauge. I drove between 65 and 70 mph most of the way. Altitude is 5000ft lower than where I started this morning. AC was on most of the way again. An amazing car! Filled up before starting out and had gone 650 miles at the half tank.
Front air dam is holding up well. Ran it up over a curb at a stop today and thought for sure I'd rip it off backing up. It just flexed up & over and then was fine.
If it weren't for necessary bio breaks and stiff joints, there wouldn't be a reason to stop all day. Meanwhile (amusingly) I see the sme 2 or 3 cars fly by 5 or 6 times... every ~200 miles or so they have to stop & fill up and then they fly by again... craziness.
Bed time now... I'll respond to your q's tomorrow
