How to check your 2019 Honda Civic’s gas tank size

If you want to confirm your Civic’s gas tank capacity by checking it yourself, here’s what you should do.

Measure the gas tank

As long as you’re equipped with a handy measuring tape and a calculator, you can find your car’s gas capacity with a simple math equation. All you need to do is find your fuel tank, measure its length, width, and height in inches, then multiply those numbers together. When you have the result, divide it by 231 (that’s the number of cubic inches in a gallon) to get your tank's gas capacity.

Check your owner’s manual

If you’re looking for the most straightforward approach, you can simply look up “fuel capacity” or “gas capacity” in your owner’s manual. All automakers include either the average or exact capacity of the vehicle’s fuel tank in their manual.

Drive till empty, then fill it up

If you don’t want to deal with taking your own measurements, and you don’t have your owner’s manual on hand, you can also get your Civic’s gas tank capacity simply by driving the car until the gas gauge hits “E”. Then, when you fill it up again at the fuel pump, just watch the meter to see how much gas is needed to refill the tank.

How to save on fuel costs with a 2019 Honda Civic

The Environmental Protection Agency (EPA) rated the 2019 Honda Civic for 32 to 36 miles per gallon, depending on its trim level, engine type, and transmission. That’s about average for a compact car, but if you want to improve your mileage, here are a few tips.
  • Don’t skimp on
    routine maintenance
    . If your car is overdue for a tuneup, you might be using more gas than you would under normal conditions. Things like poorly aligned wheels or old fluids can contribute to reduced gas mileage.
  • Drive safely. The less you speed or slam on your brakes, the more you might be able to extend the time between visits to the gas station.
  • Try not to idle. Making sure to turn your car off when you’re not driving means you won’t use excess gas.
