Fuel avg MPG sux

SyndicateZ · Nov 12, 2022

2019 limited stealth 22" wheels (not the MAX)

I do alot of stop and go type city driving and Im averaging 13.5 MPG. Is this normal? My 07 gas guzzling Navigator V8 averaged 12.5 in same conditions...I thought these v6 Ecoboost engines were good on gas comparably....plus the window sticker says it should be about 17 MPG City.... was I lied to or is something wrong with the engine possibly? What do you folk average in the city?

I don’t even get that low when towing my boat. I average about 17 city and combined about 18.9. I’ve got 6500 miles on my ‘22.

Where I live there are a lot of lights and hills so I am getting about the same you are. I have noticed on relatively flat highway terrain I am able to get 23-24 mpg. With towing it's absolutely terrible around where I live; again, better with flat terrain. Really it depends on your style of driving, environment and weather. Try the ECO mode and see if there are any differences. I do see a small increase in mpg when I do but I prefer the responsiveness of Normal or Sport. You numbers seem normal to me.

Yes, it’s terrible in the city (the ‘city’ rating is not really city that people experience in the real world. Just use it as a relative comparison to other vehicles). A couple of bursts of acceleration in this vehicle can wipe out any gains you might have.

I don’t think ECO mode helps much, if at all, except that it modifies the throttle response so that you don’t accelerate as fast for a given throttle input.

I’d find a decent stretch of highway (interstate) that’s relatively clear and flat and drive the speed limit for 20 minutes or so and see what you get. This should demonstrate if you have an engine problem or not.

Seems low, but it is a 6000 pound brick. Not quite the Prius. I'd say I get 17 as a rule running around. 22 on trips that are mostly hwy. If your gentile, flat road, keep around 65, you could see 25-26. The way I see some people accelerate from traffic lights, I wouldn't be surprised by how low some might get.

Sounds about right to me. My wife drives ours in suburban/urban driving and she believes the gas pedal is either on or off. Never travels more than 10 miles to get to work, store, kids school, etc. Engine is barely warm when she shuts it off again, and there are a lot of hills in our immediate area. She gets about 14.

Sounds about right. If your foot is constantly pushing the "go" pedal, theres no way the v6 is saving your gas. These trucks get relatively great mpg, but only on the hwy, not the way your driving it. Change you gauge to the instant fuel usage screen and keep it over your avg line.

So what does the "eco" stand for anyways in Ecoboost? cause im not impressed in the "gas saving" marketing if its getting pretty much same as my 07 navigator...

Ecoboost is a versatile engine, it allows you to get good mog if your patient, or stout power if you want it. However, you can't have both. My 09 nav would generally avg 19 mpg on the hwy, but my 18 expy would avg 24mpg in same conditions. However, both would avg 14-15 in stop n go traffic or driving in town alot because your constantly in the boost. However, the expy would never feel as lethargic as my nav in city conditions, unless I left it in "eco" mode. I purposely on both vehicles would drive with the instant fe screen up to keep the avg up. It def can be done, my 18 was at 21mpg avg when I turned it in, but its about patience. If you dont want to do that, which most people dont because they like the feel of the ecoboost power, than you will get the mpg you're getting.

I too have a 19 Limited Stealth HD tow with the 3.73. In Los Angeles, I get 12.5-14 regularly within the city and I baby it. Open highway, 18-20 mpg with maybe gains to 21 mpg in Eco Mode. I imagine people netting better mpg have the non tow package with the taller center section gearing otherwise I don't know how people are getting 22 plus mpg on the highway? Could it be 93 octane which we can't get here in CA?
