Is my mpg reasonable?

Hi everyone.

I have had my 2021 - Max limited 3.5L EcoBoost for about a month and a half now, did a bit more than 600 miles on it, and did about 3 full tank refills. I'm lucky if I do 12mpg! Doesn't matter how "gently" I drive - the best I saw it do is less than 15mpg. If I drove it any slower where it counts most - from a full stop - I would be arrested for holding back traffic accelerating like a kick scooter...

What's up with that?

I'm talking combined driving here - about 50/50 city and highway, and on the highway - I'm getting the 15-16mpg at the most looking at the "real time" average fuel consumption display, driving at about 65-70mph, on around the 1,500rpm level - the average trip mileage gauge shows about 12mpg throughout a full tank. Forgot to mention I'm not towing anything, relatively flat road on average, and with just me in the vehicle...

What's up with that?

Thank you for everyone's helpful responses. I bought the vehicle used with about 36,000 miles on it about a month and a half ago.

It rides on the stock 22" all terrain tires, and I either drive it in normal or eco mode. I make an effort to accelerate rather slowly - as I wrote - to a point where I've already had drivers behind me honking sometimes, so I try not to be doing it like a fully loaded 18 wheeler, but it's far from "flooring it" or even somewhat "flooring it"...

It's a Max, and has the towing hitch (albeit still covered by the plastic tender cover that goes over it, as I don't really need to tow anything at this stage), and it's only me in it - not loaded with people or cargo.

I live in a suburb outside Toronto, work from home, so other than three trips a week going between very little traffic city driving to get out of my suburb (which is very close to the highway) and then again when I get into Toronto itself - the rest of my drives so far were in very light traffic city driving in my suburb for groceries and such - to doing about 200 miles roundtrip on a proper highway toll road (highway 407 ETR) to the dealership a few times for some repairs.

19 limited stealth edition w/ HD Tow, 3.73 gear 4x4 (not the max)

I get about 12.7 mpg "real time" with Alot of stop and go City driving (without using auto stop/start feature) no towing and just me easy driving

When im looking at the real time fuel economy guage my fuel economy bar is between 4mpg-7mpg when accelerating from a red light lightly which kills the mpg overall.

purely On the highway im at about 19-23mpg range

It'll improve a bit as you break in the engine, but if you've got the HD tow (not listed in your specs) then that is not all that far off from ours. We get between 12.5-14 on my wife's daily commutes. No highways, just suburban stop and go.

I've 20K on mine with the HD tow, 3:73's, 4X4, get consistent 19 combined and 22 on the highway depending on traffic. Not a max though.
What are you running for tire pressure? It should improve after 5K

I have a 22 with HD tow and SPP. I’m about 50/50 and I average 17-18 combined. 12 seems extremely low.

I have 2018 hd towing w/ 3.73s and tuned running 93 octane. On freeway I can get 22mpg around 70 to 75, BUT in town I get 12.5 or so with all the lights and my heavy foot. This is all running in normal mode.

I've gotten 15.3 on average consistently for the last 4 years. 2019 XLT, no tow package.

If I leave it in sport mode for most of the tank it dips down into the 13s.
