The 2017 Honda Civic’s 12.4 gallon tank is standard on all trims.
Just as important as knowing approximately how many miles per gallon you can get from your car, it is always good to know about your car’s fuel tank capacity. That said, how many of us can actually say we know how much gas our car can hold? 
Luckily, this information can be found in your car’s owner’s manual, but there are several other ways for you to find it out on your own.

How to check your 2017 Honda Civic’s gas tank size

Don’t trust us? Or maybe you just want to double-check for yourself. Whatever the case, here are some tips you can use to double-check our numbers on your Honda Civic’s gas tank, or find the tank capacity on any other vehicle.

Measure the gas tank

You’ll need some tools for this one—get a trusty tape measure and a calculator (or some scratch paper if you want to do things the old-fashioned way), and get ready to flex those high school math skills. To find your gas tank’s volume, just multiply the width, length, and height, and then divide the answer by 231 (which is the number of cubic inches in a gallon). 

Check your owner’s manual

2017 isn’t too old, so hopefully, your owner’s manual is still in your glove compartment. Your gas tank’s capacity will be listed under “fuel tank capacity” or something similar.

Drive till empty, then fill it up

If you’re really feeling up for a challenge, and you’re looking for an adrenaline rush, just drive until your tank is empty. When your tank is on E—hopefully you’re near a gas station when this happens—just fill it up to the top. This won’t give you an exact measurement for your gas tank, but you’ll get the gist. Maybe bring a spare gas can along just in case.

How to save on fuel costs in a Honda Civic

Depending on the model you have, your Civic can get up to 32 miles to the gallon, combined. This is well above the average for compact sedans in the U.S., but that doesn’t mean you can’t still look for more ways to ensure you’re not wasting money at the gas station. Here are some tips to ensure your Civic is operating at peak efficiency:
  • Keep up with maintenance. Keeping on a
    routine maintenance schedule
    is one of the simplest and most effective ways of keeping your car running efficiently and increasing its longevity.
  • Drive carefully. You’re not in the movies, so don’t drive like this is The Fast and the Furious. Speeding and quick acceleration are one of the simplest ways to decrease your fuel efficiency.
  • Avoid idling, especially in cold weather. Contrary to what you may have learned growing up,
    warming up your car does very little for the car
    , so no need to waste fuel there.
