overall gas mileage decreasing

I've noticed that the gas mileage on the 2018 crv ex is decreasing. It's averaging now 24mpg - way under the average mpg noted on the sticker. Any solutions?

have you ever reset the "A" mileage when filling w/Fuel? if you don't it keeps on going and going and I believe you won't get a fair reading from your recent drive.
I remember reading the sticker and the Mileage is based on 100 miles and however way they test it?

No way does it say we put in Winter gas and ran 100 mi. came out with...
No way did it say we put in Gas with additives and ran it 100 mi , came out with...

So there is no way of knowing what each person gets, due to Weight in car, Tempeture of the days driven, Inclime, decline, etc..

If you gotten good mileage one day and starts decreasing, could you start telling us how your History of driving was..

Because I see people just push the Pedal to baby the cars. with no means to save on gas....

short drives and idles will affect the mpg's....
I would set the Trip A setting to reset at each gas refill, and Trip B for manual (for your road trips)

if you look at your trip history after a reset, you will notice that if you did one short trip and one long trip the two averages and mpg will be between the two readings.... the short trip will have a much lower number thus messes up the mpg numbers.
I remember the time when we first bought our CRV last year in May. Was getting 33 mpg. Then over the winter, it went down to 28 mpg. Same driving pattern. We'll see if it gets back to 33 mpg this summer.

I'm in a very similar situation. I'm hoping it starts to creep back up, now that we're exiting winter.

Where I live during the winter they use a different blend of fuel that causes a reduction in fuel economy. Their are also other factors. https://www.fueleconomy.gov/feg/coldweather.shtml
Lets remember to check the tires make sure they are properlly inflated and I did not read here about Nitrogen put in them Lol
A couple thoughts of a general nature. Well, three thoughts.

1) Those numbers on new car window stickers are close to fiction. Not necessarily false, but kind like the photos on a T.V. Dinner. How close the numbers (or the photo) come to your ‘reality’ is relative and subject to interpretation. For me, those numbers are for comparing one car’s fuel economy to another car’s. Therefore, I expect a Toyota Prius to get better mpg than a Chevy Suburban - but I won’t be surprised if neither actually achieves the sticker numbers. Lower your expectations and you’ll be happier.

2) Actual mpg on any vehicle will be affected by many different things. Yeah, stop & go driving will suck the fuel a lot faster than steady highway speeds; four butts will use more than only one; a heavy foot - passing, acceleration, etc., is tougher than easing it out. Cold air is denser, as is sea level. Hot air & 5000’ elevation will bring a grin at the pump. Remember to compare similar trends & conditions.

3) if all else fails, stop thinking about numbers and just remember that “it is what it is”.

Enjoy the drive!

Yea the day went South fully loaded 3 people in and less fill ups 40 mpg and my car was against a rhino to his biopoop spot Lol

each fill up differs to many reasons I won't list one Lol

AkA Roadster because that was my handle back then.
will again remind:

my crv is pretty constant for highway and city driving... but then I am good doing a reset of the counter to get a fair reading.
Dude stop with the blue, 90% of people can't read that unless their sitting at a desktop in very perfect lighting. It hurts to look at.

Log the mileage and calculate it each fill up, do not top off...
Personally, I don't put much stock one way or the other in MPG readouts. As others have stated... so many variables are at play with respect to how the number is realized at any given point in time. I will use a trip meter setting for a long drive during vacation or something... more out of curiosity then anything else. At a macro level.. a long trip will tick my MPG upward, and then when I return to in town driving (which I do most of the time) it begins to tick back down over time. The MPG ratings on the factory stickers are achieved under controlled and repeatable conditions and processes (to demonstrate a compliance level more so then average driver attainability).

What I DO however do is I keep an eye on the instant MPG bar as I drive... because that gives me a good instant view of how I am driving in terms of acceleration. I mostly do in town driving... so it is normal for my total accumulated MPG to be in the lower 20s. For me personally, on days when I am behind schedule or otherwise in a rush.. I definitely notice my foot is heavier on the pedal and will use the instant MPG bar to remind me to ease up a bit. It is also a good method to gain general awareness of how my CRV is doing as well... as if there are any throttle problems I will see them as an abnormal event in the instant MPG. A good reference example of this would be the differences when the vehicle is started for the first time of the day and the engine is cold VS a warm engine. Generally around town, on a warmed engine, when simply driving down the road at speed.... my instant MPG readout will be between 35 and 45 MPG. It's all those starts, stops, and waits at intersections that really eat in to the fuel economy... though I would note that at idle the vehicle seems to not pull much fuel at all (simply based on watching the miles to empty readout showing no draw down on MPG if idling for as long 5-10 minutes). Acceleration from stop (or passing, etc) though is where I think most of us chew up fuel with this engine... particularly given how little turbo-lag and how smooth and robust the acceleration characteristics of this engine are.... it simply teases the driver to juice it some. :) I admit I will accelerate to speed in town fairly quickly and then ease back on the throttle and cruise in that 35-45 sweet zone as I go down the road. I have no idea if softer accelerations for me would alter my fuel economy much (I'm sure it depends on the number of intersections stops).

On paper (ie: the factory stickers) my 2017 CRV would pencil out at about 30-35% better MPG then my old 2008 CRV.. .and in fact.. comparing long term MPG number readouts... low and behold that is about what I am seeing with the 2017 CRV... so that to me is the best measure of improved engine fuel efficiency as it is in the context of my actual driving habits and conditions.

Anyway... this sort of topic very much falls into the ever popular meme of "your mileage may vary" :) :)

Wow! really 33 mpg consistently? I really try to drive light footed, even highway miles (several trips to Dallas and Tucson from Albuquerque) usually cruise control, and I rarely get more than 30. Highway speed also greatly affects mpg, anything over 60 and mpg starts going down.

Could be the effect of a new car/broken in engine? I don't know but I was satisfied with the 33 mpg back then. Nowadays seeing it at 28 mpg is kind of disappointing. You are right. Speed limit today is mostly 70 mph and I would be doing 76-78 mpg cruise. MPG does suffer at that speed.
I have a 2018 Ex FWD. Overall I am pleased with my mileage. During the winter I averaged 24 - 28 mpg in mixed driving. Now that it is warmer, I have achieved as high as 35 mpg overall while on a road trip. The mixed driving around town and some highway is between 28 and 30 mpg. I usually do not have the ECO setting engaged.
so going 70 plus you want higher mileage????
It may be the gas. Depending on your location, summer blend gas that uses ethanol provides poor gas mileage. Check ethanol % an try a different brand or blend with less ethanol.

It could also be something inhibiting performance: low tire pressure, clogged air filter, etc.
I may be imagining this, but it seems on my CR-V "post fix" the mileage results are much more sensitive to how you drive in the first couple or so gallons when the tank is filled up. IOW, if I fill up the tank and in those first couple of gallons drive pretty hard (a lot of stop and go local traffic), getting maybe in the mid-20s, then afterward it doesn't matter how light of foot I drive - the mileage will never get up much past 27. But, if in those first couple of gallons, I happen to take nice easy drives where I can see my numbers hit 32 or 33, then I will usually wind up with 29-30 or 31 mpg by the end of the tank even if the driving after that is mostly urban. It almost seems like the overall mileage algorithm is heavily weighted toward how you drive from within the first couple of gallons of a new tankful. Like I said, this could just be my imagination.
