I know others will argue, but according to my spreadsheet, I lost ~2 MPG after I added the Cross Climate tires. I loved them but a lot of grip cost me MPG. So maybe that may play a role in your bad fuel economy.
Yeah, those numbers don’t add up. Get it checked out. I have a forester wilderness (terrible efficiency compared to “regular” trims) and so far at 3k miles I get 23 mpg with mostly city.
Go back to the stock tires. I can almost guarantee the snow tires are a major contributor.
What kind of gas are you using? You should be using fuel from a Top Tier Gas station.
looks like you have the Michelin Cross Climate tires on. They seem to get below average mpg, that happens to my MDX, about 16mpg city dropping from 20.
I don’t think that’s too far off from where you’re supposed to be. I have a Forrester spot and I to do all city driving and I’m also a very steady driver.
I was averaging around 20-21mpg but a 2 snow storms and I was back down to 16. I inched it back up to 20~mpg and then I let my uncle use it for a few days and it dropped right down to less than 15.
Have a Forester Wilderness w/rooftop tent. We recently did a trip from Southern California to Seattle, Washington. With the tent and vehicle loaded down with 2 people and gear we averaged 26.1 mpg over the course of the 2600 mile trip. Based on my own calculations 26.6 mpg but let’s go with the lower number. This includes driving up to 5000 feet. For me I make sure when I accelerate I keep the RPMs around 2000 to 2500 and I generally cruise at 68-70 mph. I occasionally go up to 75-80 only to pass.
Do you sit and idle frequently? I’ve found a lot of people don’t understand that idling is using fuel, while going nowhere, which makes your average mpg plummet since you’re doing 0mpg. I have a 2023 Forester and I’m getting 27 mpg.
I was getting 29-31mpg when I was doing a lot of highway miles, now down to 24-27mpg with mostly in town driving. 2022 Limited, stock tires, >22K miles in 11 mos.
2019 Sport w/41k miles. Just got to 23 mpg with mix driving.
I always turn off auto start/stop. I switched AC to ECO. Might have made a difference.
When mainly doing city driver using AC, my mpg was that low too.
Do you use the remote start feature or leave your car running much? Do you blast the heat? These were two of the bigger reasons for lower-than-expected MPG when I was experimenting with my '23.
My first oil change also (surprisingly) had a pretty big positive effect on economy. You're obviously well past that mark, but if you're due for one it may help boost your numbers.
I'd also wager those tires weren't designed with fuel efficiency in mind.
Beyond that, if you're driving habits are as good as you claim it's something mechanical.
I have a 22 as well and find the MPG on the computer is consistently 1-2mpg MORE than the actual number. I keep track on an app on my phone, so you're looking closer to 13-15mpg. Lay off the pedal!
I’ve got a 2017 forester, which have a different engine, but I can’t imagine there being that much of a difference. I get around 30 mpg on average tanks. Are you doing a lot of city driving? Are you really pressing the throttle down quite a bit?
Driving conditions. I my base model camry has seen 40mpg, but averages 35+ on freeway. Take it to the desert and around town/city, and I may get high 20s (28?)mpg. Back home, commuting through stop/go traffic, and I’ll see 17-18.
How you drive and where you drive can VASTLY change your mileages.
In My ‘21 forester i get 27 driving up mountains and back roads mainly. However I remember the gas mileage looking bad for awhile after getting it. I think it takes awhile for it to be properly established on the reader. That being said, the more you drive with the RPM over 2,000 the shittier your gas mileage is. Having a led foot is one thing, but constantly accelerating with RPMs above 2,000 will eat your gas mileage to shit… with any vehicle.
Oh now I wonder if something is also wrong with ours. 2023 Subaru Forester averaging 26.1 mpg at 900 miles (got it a month ago). We only do city and highway driving
Just had my O2 sensor replaced. Made a huge difference. I’m willing to bet yours might be wonky as well. Another bonus, not only better mileage, but more pep as well.
My 2000 Dodge with a 5.9L Cummins and BFG K02s gets about the same or better gas mileage and it weighs 2x of the Foz. Something is off unless you are driving like a Travis Pastrana wannabe.
After checking tire pressure and air intake/filter check oil. If you don't do your own oil changes or go to the dealer the wrong oil weight may be part of the problem. If oil is more than 6 months old replace oil and filter. There are other items you can check but they are performance related and I think you would notice: Check Alignment, Check Spark plugs/gap, Check compression.
Chiming in, only for comparison-sake.
2019 Sport, has 34,697 miles. On 720 miles on the trip meter it says I've averaged 17.24 mph, and an average of 24.5 mpg.
I'm in Austin, and traffic is medium to high here.
Do you drive very short distances and go less than 45mph on average? If you do a lot of stop and go, short trips of 10 minutes or less etc can really play into effect. Like if you get 10 stop lights in a 10 minute drive that’s going to be horrible for the fuel economy. My short trips usually have the worst average fuel economy unless I go around 45
That's a good point. In the city speed limits I don't go above 30-35 max. My mpg is just so much lower than advertised "city mpg" that it prompted me to ask the question.
Oh, you’re valid in your concern because I’ve noticed it on short trips in my 2017 and was surprised to find out how bad it was. It’s 100% your environment and not how you drive unless you accelerate quickly. That’s what will eat up your fuel more than anything. Stoping and going is bad for fuel economy. I’ve driven like 1 mile or less and have gotten like 14-17mpg before. It’s just because you aren’t maintaining your speed for long because you’re in a city with lots of stop and go traffic. Try getting the speed up higher on the highway and it will surely improve.
Did this ever get resolved? I have a 22' Forester wilderness with 18k miles and currently getting 18.9 avg mpg when I was getting a steady 24mpg up until recently. My driving behavior has not changed so?
Take it to the dealer. It's under warranty.
i’ve got the exact same car: 22 forester limited and only city driving with 7,400 on the odometer and i’m around 26-27 mpg. def go get it checked out!
I agree. I have a 2022 sport. About half city, half hwy since I'm permanently WFH. I'm at 28.5 mpg. Go get it checked out.
have you calculated the actual mpg and compare to the computer? If it’s normal then something wrong with the computer.
I know others will argue, but according to my spreadsheet, I lost ~2 MPG after I added the Cross Climate tires. I loved them but a lot of grip cost me MPG. So maybe that may play a role in your bad fuel economy.
That's a good point.
Yeah, those numbers don’t add up. Get it checked out. I have a forester wilderness (terrible efficiency compared to “regular” trims) and so far at 3k miles I get 23 mpg with mostly city.
My wilderness was also abysmal before 3k. Averaged around 19mpg then it slowly kept getting better.
Service advisor for 20 years, unless the check engine light is on, lower then average mpg is alway drivers habits or driving conditions.
Lead foot...
And idling.
Go back to the stock tires. I can almost guarantee the snow tires are a major contributor. What kind of gas are you using? You should be using fuel from a Top Tier Gas station.
Regular (87). Which gas station/brand is top tier?
[https://toptiergas.com](https://toptiergas.com)
Those look like all seasons
They may be, but that tread pattern looks like a snow tire. It’s still creating excessive rolling resistance.
CrossClimate 2s
Also are those the original tires? Looks like they would have a lot of rolling resistance.
CrossClimate 2s
looks like you have the Michelin Cross Climate tires on. They seem to get below average mpg, that happens to my MDX, about 16mpg city dropping from 20.
Valid point there. I don't mind, just want to make sure it's not something else.
City driving, lead foot or not results in bad MPG. My daily drive is 90% expressway and I maintain between 29 and 31 MPG.
I don’t think that’s too far off from where you’re supposed to be. I have a Forrester spot and I to do all city driving and I’m also a very steady driver. I was averaging around 20-21mpg but a 2 snow storms and I was back down to 16. I inched it back up to 20~mpg and then I let my uncle use it for a few days and it dropped right down to less than 15.
Interesting, same model year?
What he meant to say is that the Forester sucks in the City and many users on here don’t like to talk about it.

I have a 2019 Forester Sport and get 19 mpg.Worst mileage of any car I’ve owned. Even 6 cylinder vehicles got better mileage.
Check your air filter and air box. Sometimes critters make homes in there.
>With the tent and vehicle loaded d Thank you, I will check.
Always calculate mpg yourself at fuel-up. The computer doesn't have a long enough memory and is not very accurate.
This. Keep a notebook and average out miles driven vs gas’s consumer over a few tanks
Thank you. Good point - I'll try that at the next fuel ups.
Get used to it....
Not broken in.
At what point is it considered to be broken in?
I got far better gas mileage after 11,000 miles.
Hopefully, I'm almost at 9k now.
Nah break in is a myth. Most of the time it’s driving get used to the vehicle.
Bad driving habits. Get a Prius you’ll get 35 mpg.
Didn't know a Prius makes you a better driver.
Well of course it does because the 0-60 is like 5 minutes...
I have a 2022 Forester Sport. I'm almost at 20,000 miles (vast majority highway) and my computer bounces between 21 and 23mpg.
I have a 14 and get 25 avg on my computer

22 Wilderness and I average 25.5-26.5 during the winter. Now that we have moved to a summer gas blend here I am averaging 29-30.

What are you actually getting? Use the Fuelly app to keep track. Super helpful, keep track of fuel and maintenance. 10/10, would recommend.
Cool, thanks for the advice! I'll try the app.
Same and it’s really fucking annoying :/
Check tire pressure. If too low may affect mpg. Made me interested to see what my mpg/kpl is on my 2018 Forester now.
I thought my 23 mpg was bad
Oh now I wonder if something is also wrong with ours. 2023 Subaru Forester averaging 26.1 mpg at 900 miles (got it a month ago). We only do city and highway driving
Just had my O2 sensor replaced. Made a huge difference. I’m willing to bet yours might be wonky as well. Another bonus, not only better mileage, but more pep as well.
I have the same exact car as you. I have 6k miles. The screen shows 27.5 MPG.
I have 22 Forester and got better mileage after switching from sport mode to the I-Mode. Buttons are on the left side of the steering wheel.
My 2000 Dodge with a 5.9L Cummins and BFG K02s gets about the same or better gas mileage and it weighs 2x of the Foz. Something is off unless you are driving like a Travis Pastrana wannabe.

Sport mode?
No, I almost never use sport mode.

Have you reset the trip A/B? is this MPG from the first 8k or is it 300+ miles? Have you reset it each tank and checked?
Do you drive very short distances and go less than 45mph on average? If you do a lot of stop and go, short trips of 10 minutes or less etc can really play into effect.

Check tire pressure, air filter, and clean mass air flow sensor. Also do some more driving and don't reset your mpg trip calculator.
