How Many Gallons In A Honda Civic Fuel Tank?

Knowing how big a fuel tank on a vehicle is can be an important part of trip planning. If you are considering a Honda Civic for your next excursion, we can help you figure out how many gallons this tank will hold. We've done the research so that you'll know for sure.

The 2022 Honda Civic has a fuel tank that will hold 12.4 gallons of gasoline. The same size gas tank is equipped with all four trim levels of this year's model. The fuel economy for each trim level does vary, however.

Now that we know how many gallons of fuel the 2022 Civic's tank will hold, we'll take a closer look at the fuel economy across all trim levels. You might also be wondering if using the cruise control will save you gas, or how far you can drive the Civic when it's on E. We'll answer all of those questions and more ahead in this post.

What is the fuel economy for the 2022 Honda Civic?

Earlier in this post, we saw that while each trim level of the 2022 Civic has the same 12.4-gallon gas tank, that the fuel economy differs from trim level to trim level. Let's take a look at each one so you'll know what to expect on the highway and in town.

2022 Honda Civic Touring

This trim level is one of two that is equipped with a 1.5 liter 4 cylinder turbo engine. You'll be able to get an average of 38 miles per gallon on the highway with this vehicle. The city mileage averages 31 miles per gallon.

2022 Honda Civic EX

The second trim level with the engine mentioned above also gets great fuel economy. Expect an average of 42 miles per gallon on the highway with the Civic EX. In town, you'll average 33 miles per gallon.

This means that the EX has the best fuel economy of all four 2022 Civic trim levels!

2022 Honda Civic Sport

The Civic Sport has a 2.0 liter 4 cylinder engine under its hood. It will average 37 miles per gallon on the highway. Driving in town will yield an average of 30 miles per gallon.

Though still an impressive fuel economy, the Civic Sport rates the lowest in this category among all 2022 trim levels.

2022 Honda Civic LX

Finally, we have the LX. Though equipped with the same engine as the Civic Sport, it gets better fuel economy than its counterpart. On the highway, the LX will enjoy 40 miles per gallon. In town, it averages 31 miles per gallon.

How far can the 2022 Honda Civic go on a full tank of gas?

Determining how far any vehicle can drive on a full tank of gas requires two pieces of information and an easy mathematical equation.

You'll need to know the size of the fuel tank and the average miles per gallon, which we covered earlier in this post. Multiplying the number of gallons by the fuel economy will yield the number of miles per tank.

If you recall from earlier in this post, the fuel tanks are the same size across all four trim levels of the 2022 Honda Civic. However, the fuel economy is different. Applying what we know about each trim level, we can list how far you can average per tank from each:

  • The Civic Touring averages 471.0 miles per tank for highway traveling.
  • The Civic EX averages 520.8 miles per tank for highway traveling.
  • The Civic Sport averages 458.8 miles per tank for highway traveling.
  • The Civic LX averages 496 miles per tank for highway traveling.

Some factors can impact fuel economy. We'll discuss two of the most important in detail ahead in this post. Here, we'll look at variables you can control that will potentially reduce your fuel economy:

Driving at high speeds

How you drive will certainly impact the fuel economy of your Civic. Rapid acceleration and excessive speeding can reduce your overall fuel economy by up to 30% on the highway.

Experts maintain that keeping your speed at 60 miles per hour is the optimal way to get the best fuel economy. While this is not always practical, know that you will reduce fuel economy a bit for every increment above this speed.

Not maintaining your vehicle properly

Every vehicle needs to have routine maintenance performed at factory-recommended intervals. Failure to do so will not only reduce the useful life of your Civic but will also impact the fuel economy. 

Get your Civic maintained in accordance with the instructions in your owner's manual!

Excessive weight on board

The more weight any engine has to propel forward, the more fuel it will consume.

While people won't use a Civic as a towing vehicle typically, being aware of the amount of payload onboard is important. If you have a full car of people and a trunk full of luggage and/or gear, expect the fuel economy to decrease.

Every additional 100 pounds can reduce your vehicle's fuel economy by an average of 1%. Be sure you factor that in when planning a long trip with a carload of passengers.

Does cruise control save gas?

Most modern vehicles are equipped with cruise control as a standard feature. Not only does this make long drives more comfortable, but it will also save you on gas.

Experts state that utilizing cruise control on long highway trips can save you nearly 15% of fuel economy.

Having your speed set eliminates the need for you to over accelerate and brake. And smart cruise control systems take the guesswork out of how much you should do of each.

Keep in mind that any form of cruise control is no substitute for alert driving. Pay careful attention to the road and be prepared to brake when necessary!

Does turning off the air conditioner in a car save gas?

In older model vehicles, the air conditioner running can make a noticeable difference in the fuel economy. But while running the air in a modern car might make it consume a bit more fuel, it's not enough to be impactful.

You might be tempted to open your windows on hot days to avoid running the air and burning even the slightest amount of fuel. However, driving around with open windows increases wind resistance. This makes your engine burn a lot more gas than just running the air conditioner.

Driving around in a hot car isn't safe. It makes you less alert, and more stressed, and can even make you sleepy.

Even if running the air were to make a big difference in the fuel economy, it's better to have it reduced a bit than to risk your safety.

How far can a Honda Civic drive on E?

Sometimes we don't pay attention to how much fuel we have left in our tank until we're nearly empty. If this happens to you in a Civic, you'll want to know how much you can be expected to drive when that gauge rests on the dreaded "E."

Hondas will have the fuel light illuminate when the fuel tank has only 1.8 gallons remaining. If you know your fuel economy, this should be an easy math problem to solve. If you are on the highway and are averaging 30 miles per gallon, you can assume that you have 54 miles left before you are out.

But don't leave things to chance. Running out of gas puts both your safety and the health of your vehicle at risk. Not to mention that being stalled on the side of the road isn't the best way to spend your day.

Final thoughts

The 2022 Honda Civic has a fuel tank typical in size for a vehicle of its class. The fuel economy on this popular sedan has historically been fantastic, and the latest model year is no exception.

Though you can get a good number of miles when the fuel light comes on, it's best to not leave things to chance and get to a gas station to refill as soon as possible. Drive safe!
