My daughter had a Girl Scout event at SeaWorld yesterday. We took the F250. I filled up and reset the trip odometer. At 70-75 it was getting just a smidge over 19 MPG, at 80-83 it was at 18 MPG, at 90 it went down to 17. On the way back I got behind a new Acura NSX (bright orange) along I-10 and was doing 90-95 for 25 miles or so. When we got the 130 I let the wife drive and she continued at 90-95.. ended up with an overall average of 16.8. Oh and San Antonio traffic on Saturday can suck my balls.. stayed at a hotel on the Riverwalk and it took 25 minutes or more to go 1.2 miles. At the hotel I said "valet this thing". Best money ever spent. So 16.8 with a LARGE amount spent sitting in stop and go traffic. Not bad. Oh and kids GS thing was cool, they spent the night at SeaWorld.. slept in the dolphin enclosure, she could see them all night. Got VIP seats to Shamu, VIP seats to a Bald Eagle show (or something with them). Plus behind the scene tours of the shark tank and penguins, and she got fed, just a cool experience. She was woke up at 6AM to go feed the Sea Lions and more behind the scenes stuff. Judging by the photos she was not happy about the 6AM awakening but she loved it.
