That's still amazing, after the break in I'll be going to Byron or Union Grove, will be driving like an old lady to get there to see how well it does. The 20's don't come with decent tires for racing so the plan is to get tires as well.

Another Northern Illinois Mustang guy, congrats on the new car. I bought my S197 5.0 track pack 5 1/2 years ago with 3,700 miles at Rock River Ford and was averaging around 17 mpg on a tank until about 6,000 when it went up to 20 mpg average. My lifetime mpgs is 19.5 mpg over 20,000 miles and computer is fairly accurate.

19 GT here and I get about 25-27 mpg on the hwy, even after driving 200-300 miles straight. Speed between 65-80. In the city, if I’m being responsible, lol. I get between 15-17mpg.

I just adjusted my AFE on my 19 GT. I'm hitting around 18.5MPG on my commute. I've been using Speedway and Costco 93 octane.
About 20 out of the 25 miles I drive to work is highway. Most days I'll cruise around 80mph with traffic. Even doing 85-90mph, the mileage doesn't change much. I'm surprised since the car has a 3.73 rear end.

Did you reset the average?

Every fill-up I reset the average MPG and trip 1. Trip 2 I use for tracking different events.

I'm also using the GasBuddy app to help track as well. Seems that the car runs consistent with Costco and Speedway premium fuel.

With only 600 miles on the engine I just got 27.5mpg on a 2 hour commute, cruise was set at 75mph.

Im averaging around 20 in my pp eco with a fp tune, mostly driven in sport mode. I deal with horrible commutes in Chicago and Denver which pushed me in the eco direction, that and it was just that much more affordable for me.

With a tight new engine on my MY19GT I'm getting 25mpg whilst running in so I imagine 29-30mpg will be possible on a long motorway run. That is using 99RON fuel here in the UK (93PON in USA) and UK gallons (20% bigger than US gallons) No Ethanol in UK 99RON yet but it is now showing up at 5% in Europe (99RON E5)

That should mean US drivers getting around 24mpg on a decent run
