Good day everyone!
Im curious you what your freeway mpg is coming out to? Ive seen some youtube vids where people got 21mpg. With my ECO on I was getting 19.1 mpg.

I was like...how are people getting 22mph?! Then on my last 2 hour drive on the freeway...I turned off my eco and got 26mpg!! Which blew my mind.

why do you think I was getting such low mpg with eco on? Isn’t it suppose get you better mpg?

Something sounds off....I keep ECO on all the time. City driving only (87-89 octane) I get 21-24mpg. Highway driving using Mid-grade (89) I average about 28-29mpg, but using Super unleaded (91) I just got 32.2mpg.

I'm about the same, I can stay at about 24 MPG on highway, ECO on, but if I include off freeway say to my house or work or store it drops to 19 pretty quickly. Still not bad.

Do you have any roof mounts? Sad to say my Thule roof rack looks like it takes a full 2 MPG from freeway.
Interesting...next fill up I’m going to put some 91 and see is the MPG changes on me.
No roof mounts yet. Thinking about a Thule cargo box.
So far, with about 1000 miles on the clock, I'm getting about 28 on the highway and 21-23 in the city. That's all with ECO on. No roof cross rails. I'm a very conservative driver. I don't find the ECO setting bad at all. I'm not sure what people don't like about it. I guess I haven't driven with out it on to know. I've read I shouldn't use ECO when towing which I'll be doing this Fall.

I have never used ECO on mine. As for why...I don't like the reduce throttle response. I like to have access to full power should I need it. I am happy to report though with nearly 21k on the clock I average 20-21 MPG in the city and 25-26 MPG on the highway. I am completely satisfied with these numbers. I also should mention...I don't personally pay for my gas...I own a company and my Passport is my company car and I use our fleet fuel card...so I guess in a way I am biased since I don't have the expense.
I track my fuel usage on 'Road Trip' app. 22.68MPG since birth and over 17,500 miles in an AWD Elite. Wouldn't dream of using ECO.
I never use ECO. About 21-22 mpg in the city and 25 mpg on the highway. If it was that important to me I would not have bought a SUV.

Mcpdallas: Wow - 21 MPG is Pretty good.
I have a 2020 Exl Awd , I never use the eco button, I use the Ac quite often and I’m using the stock 20” tires. I live in SoCal and spend quite a bit of time In stop and go traffic. My city average is 16.

My previous car was a 2017 Subaru Outback 3.6 , I was getting almost 17 mpg in the city. Considering the size and the comfort /ride, I think the gas mileage is pretty fair.
The generally accepted standard has risen from a consumption of around 8.1 to 7.1 litres per 100km (35-40mpg) in the past to more like 5.6 to 5.1 litres (50-55mpg). As a rule of thumb, vehicles listed at less than 6.0 litres/100km are considered to have 'good' MPG 🚀🚘🚦
Eco is designed to compensate for a heavy foot on initial acceleration. Doesn’t add at all on highway cruise speeds.
what seems to be missing on all of these responses is factoring for cruise speed. Different speeds will produce different MPG.
just drove my new Elite from Dallas to Lake Tahoe and back plus driving around while there 3700 miles total. 81 mph on cruise control for most of the trip. 26 MPG.
I've got the small Honda (just a rebadged Thule, I think) box, and am getting around 25MPG highway with 91.
Good morning folks!
Got my EX-L (all stock parts) for 1 1/2+ year now. Always filling it with 91 but getting only 18+ MPG in the city. That is with the ECO on.
Usually, from a full stop, my 1st gear would switch to 2nd gear at around 1,900-2,400 RPM. 2nd gear to 3rd gear would be somewhere 1,900 RPM or less.
I drive more like a parts-saver or conservative but still only getting 18+ MPG in the city with the ECO on.
Anybody getting similar MPG results?

You're getting that mileage on a Passport?? I'm no where close to that.

Yes. I am getting about 18.5 with a mix of city and highway. Love 2020 EXL AWD Passport but not thrilled with it's fuel economy.

Just drove 1,400 miles over 2 days and averaged 23 mpg.

I've had my '20 EX-L since September and I've had similar results, though I tend to use remote start multiple times every day so I'm sure that really cuts into it. My driving is very mixed hwy/city and I always leave ECO on with idle-stop enabled. My last 3 cars have each averaged nearly 30mpg so it stings a bit when I fill up the Passport, but it's not like I didn't expect it at all.

I just had my first oil change yesterday and with the warmer weather coming, I'll be interested to see how the mileage changes with the engine worn-in if I can resist using remote start. Though I wish the mileage was a little better, I really love my Passport.
Personally I think there is too little lack of description of what "freeway" driving means in a particular area is as well as the other trips include. The three big factors I see are traffic, terrain and driving style.

We don't have any big city "freeways" where I live. Three highways that run through/around town, but none are long enough to get any accurate measure of mileage.

From living in large cities with 6/8 lane freeways, I count them as in city driving with all of the traffic that is normally encountered. The speed of the freeways may help the mileage go up, but it is still city driving. Stop, go, slow down, speed up etc. which all effect the mileage.

For me on the highways going west of where I live I average 28 mpg on a calm day as they are nice and flat. If I have a head wind I may loose one or two mpg. With a good tail wind I have gotten 31 mpg, but that is rare to say the least.

Heading north or east my average mpg goes down to 24-25 mpg as the highways go through hill country. The acceleration going up will usually take more fuel than is saved going down hill.

In town i"m averaging 19 - 21 mpg most of the time, unless I get stuck in traffic usually due to an accident. When you are talking about 4 lane divided highways one good accident can bring traffic to a stand still.

I know this is an old thread, but just discovered it. Recently I filled up and drove about 70 miles on a two lane highway (not freeway), no stopping, some of it through hills. Speed never exceeded 55-60 mph. I stopped to take this photo. Before stopping for the photo the mpg at one time was actually 33.1
