How big is the gas tank on a 2012 Honda Civic?

The
2012 Honda Civic
is a compact car with excellent fuel economy, making a fuel tank capacity of 13.2 gallons more than enough. A Civic Natural Gas (original MSRP at $26,305), however, can only carry 8 gallons, so you might want to stick close to home. Considering the wide range of available powertrains, it’s hard to know what gas type to use. Here’s the best gas for each version of the 2012 Honda Civic:
Model

1.8L four-cylinder

How to check your 2012 Honda Civic’s gas tank size

Here are a few easy ways to measure the fuel tank size of your car on your own:

Measure the gas tank

For this method, you’ll need a measuring tape and a calculator. Find your vehicle’s gas tank and record its width, length, and height in inches. Multiply your measurements, divide by 231 (the number of cubic inches in a gallon), and you’ll have the volume of the gas tank in gallons

Check your owner’s manual

Gas tank capacity is usually listed in the owner's manual of your vehicle. If you’ve misplaced yours, take a look online—Honda keeps a copy of the documentation for every vehicle dating back to the early 2000s on its
online support page
.

Drive till empty, then fill it up

Alternatively, you could drive your Honda Civic until the gas gauge is empty, then see how much fuel it takes to refill it. You won't have an exact measurement unless your car runs out right at the fuel pump, but you'll get a good idea. Simply pump the gas, check the number on the pump, tighten the fuel cap, and drive away.

As you can see, you'll be unscrewing the Honda Civic SI's gas cap far more often than the others. But with these tips, you can avoid a refill on every model for as long as possible:
  • Take care of your vehicle. When you skip regular maintenance and allow your Civic's system to wear out, your fuel economy suffers. 
  • Take care when driving. By easing off the gas pedal and avoiding sudden acceleration, you can keep your fuel consumption low. 
  • Idle less, especially in cold weather. Your gas consumption will spike if you let your car idle. To warm up your car on a chilly morning, drive it gently instead.
