So, from spring break and then this past week, I've had A LOT of highway miles racked up on my just broken in Mustang. I've been very impressed with the MPGs I've been getting, and even got to do some 1/4 mile runs on these highways as they were out in the middle of nowhere. I'm very happy with a 13.3 from an automatic, running on 87 octane, with crappy 235 tires, and my wife in the passenger seat. Can't wait to try it on a track, with some 255 or 265s and 93 octane.

They make new pistons every day, so why worry?

Those mpgs are down right impressive! Ibam also pleasantly surprised with mine as well, seeing almost 30mpg on the highway.

I have yet to use the track apps but look forward to it as the weather is starting to get nice. 13.3 is a good start in a 3700lb car for sure

I think I may drive a little differently.....I average around 21 - 21.5 when I hand calculate it. ;-)

The dash is always 1 - 1.5 high.

Near 30 with all those mods? Nice! When I just go to work back and forth, and an occasional drive to lunch, I seem to get around 24.5-25.0. This is almost identical to my '13 GT Manual.

I kept track of it some on fuelly, tracking my fuel ups, and the onboard was pretty accurate, but a little over actual.
