Budgeting for your car’s expenses is a large part of ownership. Every car is made differently, and certain specs, like gas tank size, can impact your calculations. Knowing the amount of fuel your car can carry makes estimating the price at the pumps much easier.
How big is the gas tank on a 2021 Honda Civic?
The 2021 Honda Civic has a standard 12.4-gallon fuel tank capacity across all of its trim configurations for both the sedan and hatchback models.
Gas tank size vs. fuel economy
While every 2021 Honda Civic has the same fuel tank capacity, the fuel economy varies among trims and engine configurations. That means how long those 12.4 gallons of gas last between fill-ups depends on your individual Civic’s EPA rating:
The top-tier Civic Type R hatchback will have you back at the pumps the most often. The mid-tier Civic EX and EX-L sedans are rated to be the most efficient with those 12.4 gallons.
How to check your 2021 Honda Civic’s gas tank size
Don’t just take it from Jerry! There are a few other easy ways to double-check your 2021 Honda Civic’s gas tank size.
Grab your measuring tape and calculator, and measure the gas tank for yourself! You can multiply the width by the length by the height to get your fuel tank capacity in cubic inches. Then divide that number by 231 to get the volume measurement in gallons.
Check your owner’s manual
Break out your 2021 Honda Civic’s owner’s manual to see the fuel tank size spec straight from the manufacturer. Check an index or flip through the pages looking for “fuel tank capacity” to find Honda’s gas tank measurement.
Drive till empty, then fill it up
It’s a little risky, but if you want to test the fuel capacity you can always drive your Civic to “E” and then see how much gas you use on a full fill-up. You may not be able to get the exact volume, but you’ll at least know what to expect at the pumps when you’re running on fumes.
