No idea what y'all are talking about. I converted my usual L/100km to MPG for the sake of people on this forum being mostly from the US 🤷‍♂️

It was a semi-serious joke of mine to imply the use of "different gallons" in Canada meant "Imperial (UK) Gallons"

I would assume Canadians talking in Miles Per Gallon terms for a car were using US Gallons as context ... Even though Canadians use Imperial (UK) pints for beer, and spelling the metric volume as "litre" as the UK would

Canada isn't "following UK" or "following US" usage consistently, which confuses both Americans and Brits sometimes, but that's more something to be proud of than anything else, I would say!

I recently bought a Honda Civic Sport Hybrid Hatchback, but I’m experiencing poor gas mileage. I’m not sure if there’s a break-in period or procedure I need to follow, but the car isn’t giving me the fuel efficiency I expected. For comparison, my 2016 Honda Civic averages around 33-34 MPG, and the hybrid isn’t performing noticeably better.

I’m unsure if I’m doing something wrong or if there’s an issue with the car itself, but it’s frustrating. I’m considering taking it back to the dealer to figure out what’s going on.

Has anyone else experienced something similar or know why this might be happening? Any advice would be appreciated before I take it in for service. Thank you! View attachment 23581

annalow86, I just bought a 2025 civic hybrid sport touring. Like you I'm exceedingly disappointed in the fuel mileage this Honda gets. I don't see how the he*l they can advertise the fuel mileage this is suppose to get, like 45mpg hiway, 50mpg city. Bought mine in El Paso TX and drove it home to Corpus Christi. It got about 33 mpg on the hiway coming back and with a 10 gal gas tank there's just no safety factor. Now we're driving around town it's up to 36mpg but I'd call that poor at best. I fear I've screwed myself by purchasing this at a dealership clear across the country so now I don't have a good relationship with my local Honda dealership. Love driving the car but fuel mileage is just flat embarrassing. Anyone asks me if I recommend a Honda hybrid and I'd tell em go elsewhere. They always say don't fall in love with a certain car but I was under the impression Honda had a great track record. Not sure where to go next but I'm starting to smell a class action suit. You're not the first one I've heard of who gets much less than the fuel mileage these are supposed to get.

Hybrids shine in city driving.

Not min3

I'd agree about the break in period. I think I drove about 150 miles and went to fill up after the dealer as I could tell the first tank number did seem right as this was my third hybrid owned. Regardless, I run in ECON mode, do 90+% city driving, and get about 61 mpg on a tank. This tank at over 500 miles I'm averaging 62.1. With the 10.6 gallon tank I'll get over 600 miles to the tank.
Details: relatively flat terrain in Texas, desert climate, A/C on 50% of the time, I don't drive like a hypermiler or a grandpa, and I have the 2025 Civic Hybrid Sport Touring. I don't do the odometer vs fuel numbers from the pump, I'm giving you numbers from the Honda computer which is probably a little to my benefit. One thing I learned after my wife would consistently get better mpg than me in our 2023 HAH is that she is a more aggressive driver than I was. She would get pretty hard on the gas - as in accelerate on the Power Meter (the fake rpm gauge) at about 23% to 25% from all stop lights and stop signs. It was slightly more aggressive than me since I was "trying" to get a good mpg number and she could care less. So I started doing it....step on it to about the 25% mark...get up to your speed....say 40 or 45 mph....then run super low on the power meter to keep your speed consistent. Now in the HAH we get 49-51 mpg consistently and in the Civic Hybrid I can hit the 60 mpg with all of the city driving I do. It works for us, some of you should try this method and see if you get a couple mpg improvement. Good luck and let us know if you get better numbers (or not)!

Obviously, the highway is the mpg killer, especially at high speed. When we travel across Texas at 85mph on I-10 and go through the Hill Country we get 37 or 38 mpg to a tank.

Drove my 2025 civic hybrid on I-80 back from the dealership in El Paso and had to stop for gas every 300 mi or so. Very unnerving to get that poor fuel mileage with a 10 gal tank. We got approx 33mpg hoping to get better here in town but not looking much better, 36mpg or so. As the Dude said "bummer man"

I think you should've done a bit of research and own up to a poor purchase decision instead of blaming others. Why buy a hybrid in the first place if your main driving is highway? Did you even look into how EPA estimates are done for the highway number? Hint: there's a top speed that's not 90mph. 🙄

I also don't know what you consider town driving, but there's no way you're getting 36mpg in town when lots of people are reporting over 50mpg in the city. If you did 90% highway, 10% city, and read 36mpg, then you're not reading things correctly.

are these MPG numbers you've calculated, or what you see on the infotainment screen? If they're from the infotainment screen, take a picture of how it looks now showing the poor mpg and miles on the trip counter, and then do another one in a week showing the change of miles and the mpg, would be interesting to see numbers so low.


i'm getting 50 with regular driving and low 40s highway (80% stop and go commute 20% "spirited" driving)

It may not affect you but there is a recall for HP fuel pump leakage. I would at least take the car to a dealership and find out if you're okay on that because I have driven my car over 5k miles on highways and across the Sierra Nevada mountains four times and my overall average is 48.9 mpg. I have not however done any long distances at 90 mph, more like 80-85.

 

[farmerjack]

Not sure if this will help anyone, but this is the average fuel economy I've seen over the last 2000 miles & 45 days with my hybrid. I commute at 75mph on the interstate both ways, minimal traffic. Small trips around town on the weekend & occasional traffic commuting bring the fuel economy UP quite a bit, as expected running on EV mode.

 

[S0ULDIER]

I have just under 5k miles on my touring sedan. Many highway miles, mountains, desert and dense urban traffic most in NORMAL mode with A/C on. I rarely use cruise control other than straight, level open highway. My Trip B computer has never been reset and reads 48.9 mpg. Trip A computer auto resets at each fill up and I regularly see 50+/- mpg. I have cross checked the results with manual calculations and found the computer to be accurate.

All that being said I did see my results improve over time. Whether that is from break-in or my driving habits and style I'm not sure. I think that if you watch the display that shows your estimated average over the bar that indicates your instantaneous mpg it will have a subtle, almost unconscious effect on how you drive the car and I don't mean like a jerk Prius hyper-miler. There just seems to be a method where, at any speed up to around 80, you can coax it into EV mode and keep it there for a length of time.

On a recent trip to Las Vegas and back I filled up at Lee Vining, which is at 6,700 feet elevation, and drove up to the 9,943 foot Tioga Pass at which point my meter read 20.8 mpg but after coming down to the San Francisco area which is near sea level the computer read 62 mpg. Total distance was 199 miles.

how do you get trip A to auto-reset on fill? I noticed mine hasn't on my first 3 fills and I would love that.

 

[S0ULDIER]

I thought I'd pitch in some info too. My first tank on the car, which is halfway done, is averaging 52mpg. Mix of city/highway.

Also not super reflective of realistic driving, but Toronto has something like 3rd worst traffic in the world, and the other day I took a 25km ride in stop and go highway traffic followed by downtown driving.

That drive measured 87mpg at the end of highway stop/go, and 67mpg at the end of the full trip! Low speed ACC + LKAS basically meant the car was driving itself.

The hybrid really thrives in city and traffic.

it's weird how i'm not so upset in stop and go traffic anymore. lol

 

[farmerjack]

I manually reset it. I’m not sure a functionality exists, at least not for the sport trim. Maybe the ST has something.

I also do my best to log my fuel consumption with Fuelly, so I really stay on track of recording every fill up.

 

[1000FC]

I believe its under vehicle settings, but i'll check later today when I get into car. I changed it, but just can't remember how right now. I have the touring if that matters

It's under Vehicle Settings or perhaps Trip Meter. You can choose Reset to Manual or On Refill

 

[cryptolime]

You guys are right. I did notice that the miles per gallon are lower on the freeway compared to the city, but I wasn’t expecting it to be this low. I drive over 70 on the freeway, and I use the carpool lane a lot while carrying passengers, so that might be why my MPG is lower. I was just bummed that I was only able to get around 340 to 370 miles on a full tank, which wasn’t great for me since I was hoping to get at least 500 miles, especially since it’s a hybrid.

But other than that, I think everyone here is right—people have mentioned the break-in period, which seems true from what I’ve read. Also, the way I drive likely affects it. I’m learning how to use the paddle shifters, and it’s helping me improve my miles per gallon because at first, I didn’t know what they were for. I thought they were just regular paddle shifters to increase or decrease speed since my salesperson never explained them. I never really knew what they were for.

damn, my Si gets about 490 on a full tank on the highway. sounds crazy but i did the math.

range says 409 but it only takes 10 gallons at fill-up with a 12 gallon capacity; 409/10=40.9. (40.9x2)+409=490.8 miles per 12 gallons. with city driving i tend to average 34-35 mpg. 34.5x12=414 miles per 12 gallons.

give it some time to break-in. my MPGs went up after the first oil change.

Cold weather mix of driving in only averaging 35mpg which Honda service tells me is normal. I drive like a grandma

I have a 2025 Civic hybrid touring. I am getting 49 mpg. However, I live in FL.

 

[azgman9]

I think he was referring to/thinking of what happens in the UK, where they do use miles for road distances and "Imperial" gallons for "miles per gallon" fuel economy ratings, but use a different/larger gallon than the US does, where a gallon is NOT "Imperial" but just "gallon" or "'Murican gallon". Even though the fuel is sold at "petrol" stations there in "litres". (The miles, however, are the same length.)

So over there, you can either read fuel economy as km/L where they'd have to "convert" road distances from miles to km to think about how much fuel it would take to go from Bristol to Birmingham or something, or else in Miles per (Imperial) Gallon and have to think about it as 4 Imp Gal to about 18.18 Litres (or 4.8 US Gal).

It's also why an (Imperial) "pint" of beer in the UK is more beer (20 fl. oz., a bit more than 568 mL) than a pint of beer in the US (16 fl. oz., or about 473 mL).

Even more confusing, a "pint" of beer in Canada is also defined as 568 mL. Even though when a Canadian reads "miles per gallon" figures about their car, it's almost certainly based on the US gallon.

I am actually in the same boat as you. Just bought my car last Friday. Already put 900 miles on it and my highway milage is tapped out at like 36-39mpg. I am starting to get PISSED. The better mpg was the whole reason I bought the car. I slowed down to 65 and tried to let the car go into "EV" mode as much as possible, but it still is only seeing mid to high 30s.

I got it to kreep up into the 40s with city driving, but it really seems to be struggling with efficiency on the highway. Its winter here: maybe that is playing into it? Perhaps a break in period like you mentioned?

The IC engine has to run to generate heat so that will definitely have a negative effect on fuel usage. My mileage also got quite a bit better once I had 1500 or so miles on the car.

I'm only getting 34mpg on my first tank. But it's freezing in Wisconsin and I've been in sport mode half the time.
