The Honda Civic has been around since the ‘70s, and its reputation for well-built, reliable cars has made it one of the most popular compact cars in the U.S.
It is also known for its low running costs, which would suggest that it has excellent fuel economy.
But does it deserve its thrifty reputation?
We’ve done the research into Honda Civics’ gas mileage to bring you the definitive guide to this perennial favorite’s fuel efficiency.
Read on to find out how it compares to some of its rivals, some things you can do to maximize your fuel economy, and everything in between.
Are Honda Civics Good On Gas?
For a car that runs on gasoline (as opposed to electric or hybrid vehicles), the Honda Civic is pretty good on gas.
The U.S. Environmental Protection Agency (EPA) gives all of the 2021 1.5L Civic models combined miles per gallon (mpg) of 32 or higher, with the automatic versions registering the highest numbers (the best being 36 mpg).
When broken down into city versus highway driving, the various 1.5L models range from 29-32 mpg and 35-40 mpg respectively.
Unsurprisingly, the Civic with the bigger engine – the 2.0L model – gets fewer miles to the gallon than the rest, with 22 mpg in the city and 28 on the highway, making a combined mpg of 25.
Data from actual Civic owners puts the average combined mpg slightly lower for the 2021 model at 29, although this takes into account each iteration of the vehicle, no matter the engine size.
However, the figures look better when averaged as a whole over the last twelve years as the combined mpg becomes around 31.7, which is much closer to the EPA’s assessment of the car.

Which Honda Civic Has The Best MPG?
The Honda Civic hybrid models from 2012-2015 all have the best mpg out of the Civic family, with an impressive 44 combined city/highway miles to the gallon.
New Civics are no longer available as hybrids, so when looking at the gasoline options, the 1.5L automatic turbo versions top the list: for the last five years, this model has scored a consistent 36 combined mpg on the EPA website, with 42 mpg on the highway and 32-33 in the city.
A couple of stick shift Civics come close though, as the EPA recorded a combined mpg of 35 for the 2017 and 2018 1.5L turbo manual versions that matched the highway mpg of the automatics and scored one less when driving in the city.
Honda Civic vs. Honda CR-V Gas Mileage
The Honda CR-V is available in even more versions and trims than the Civic, but since it is a bigger car, most of them have worse gas mileage.
Looking at the basic 2022 models, the Civic gets three extra miles to the gallon than the CR-V, with 33 combined versus the CR-V’s 30.
In a slightly unfair comparison, there is an option to purchase a hybrid CR-V, which naturally increases the vehicle’s fuel economy. You can expect a combined mpg of 38 in this version which beats all the latest gasoline Civics, but not the old hybrid ones.
Honda Civic vs. Honda Accord Gas Mileage
The Honda Civic fares better when comparing its 2022 sedan version against the same in the Honda Accord range. Kelley Blue Book gives the 2.0L Civic a combined mpg of 35, two more than the 1.5L Accord’s 33.
When looking at the 2.0L Accord, this number goes down even further, to 26 mpg combined.
If you really want to increase your gas mileage though, the Honda Accord offers the option of a hybrid version, which will get you a combined mpg of around 47.
Honda Civic vs. Honda HR-V Gas Mileage
Edmunds.com gives the 2.0L Honda Civic a better fuel economy rating than the 1.8L Honda HR-V, with the 2022 versions of each car scoring a combined mpg of 35 and 30, respectively.
CarBuzz echoes these figures, but again, this is to be expected, as the HR-V is a bigger car and therefore uses more power.
Honda Civic vs. Toyota Corolla Gas Mileage
Edmunds.com gives both the Honda Civic and the Toyota Corolla a plus point for their fuel economy, but which is higher?
Well, when comparing the 2.0L Civic and the 1.8L Corolla on the same website, the Civic wins. It gets two more miles to the gallon than its rival in the small sedan class – 35 to the Corolla’s 33.
Honda Civic vs. Mazda3 Gas Mileage
The Honda Civic does it again when facing another of its fellow countrymen, the Mazda3.
The 2022 2.0L Civic’s combined gas mileage is four mpg better than the 2022 2.0L Mazda3’s, with 35 against the Mazda’s 31 on Edmunds.com.
The result is the same in the 2021 versions of each car too, although the gap is slightly smaller – the Civic gets 33, while the Mazda stays on 31.
Honda Civic vs. Honda Fit Gas Mileage
The Honda Fit has been discontinued in the U.S., but we can still compare recent versions of it against the Civic.
The 2020 1.5L Fit’s highway stats are the same as the 2022 2.0L Civic hatchback, with 36 mpg, but it races into the lead when looking at its combined and city figures, which are 31 and 29 mpg, versus the Civic’s 29 and 26.
However, in a more even comparison, the 2021 1.5L Civic hatchback claws back victory in a big way, coming in with a combined mpg of 34, including up to 40 on the highway.
Honda Civic vs. Toyota Camry Gas Mileage
The Toyota Camry comes with a bigger engine than the Honda Civic, giving it a worse gas mileage than its Japanese rival.
The various versions of the 2.5–3.5L Camry offer an mpg of between 22–28 in the city, and 31–39 on the highway, whereas the 1.5–2.0L Civic will do 30–33 miles to the gallon when city driving and 37–42 on the highway.
Do Honda Civics Need Premium Gas?
Honda Civics from the last ten years should not need premium gas. They are designed to run perfectly well on regular gasoline.
This will likely apply to the newer turbocharged versions too, so save a bit of money at the gas pump by using gasoline with an octane rating of 87 rather than anything in the 90s.
Although to be absolutely sure, we do advise looking in your Civic owner’s manual for a definitive answer about your specific car’s gas requirements.

How Far Can A Honda Civic Drive On A Full Tank of Gas?
A 1.5L or 2.0L Honda Civic should be able to drive between 397 and 434 miles, depending on the model year and trim.
One forum user confirmed this, saying that his Civic gets him over 400 miles, even with a pessimistic baseline of 30 mpg.
Individual driving habits can greatly influence this number though, and what one driver is able to do might not be replicated by another. Luckily, we’ve provided some tips to stretch your car’s gas mileage a little further down this article to help you get to the top end of the range.
How Far Can A Honda Civic Go On Empty?
Data collected from real Civic owners suggests that a Honda Civic can go for an average of 43.61 miles on empty, which is no mean feat.
While we don’t recommend waiting until your car says it’s empty before filling up, this amount should hopefully be enough to see you to the next gas station.
How To Increase the Gas Mileage of A Honda Civic?
Honda Civics already has good gas mileage for a car that runs on gas, but there are things you can do to get even more miles out of a tank, from checking your driving habits, to making sure your car’s hardware is up to scratch.
Tires are an important part of fuel efficiency, and making sure they are properly inflated will add more miles between fill-ups. It is recommended that you check your tires’ air pressure every month to ensure they’re at the optimum psi.
Getting rid of any extra weight in the car will also contribute towards a better fuel economy, as your car won’t have to work as hard with a lighter load and will therefore burn less fuel.
An even simpler method is to be aware of how you accelerate and brake since a smoother pedal action uses less gas than letting rip after a stop light or harsh braking.
Don’t neglect the stuff you can’t see, either. Changing out various parts, like spark plugs, air filters, and the oil when needed will all add up to fuel savings too.
Does a Honda Civic Waste a Lot of Gas?
Generally speaking, Honda Civics has good fuel economy and does not waste a lot of gas. If you notice a significant drop in fuel economy, it could be due to a faulty fuel system.
Make sure to follow the regular maintenance schedule to give you the best possible chance of avoiding any component breaking down.
What Type of Gas Is Best for a Honda Civic?
Honda Civics runs best on regular unleaded gasoline, which typically carries an octane rating of 87 in the U.S.
Always check your car’s owner’s manual if you have any doubts about the best type of gas for your car, as that will tell you the minimum recommended octane rating of the fuel you should use.
