Depending on your car type, the average gas tank capacity usually ranges from 12 gallons to 15 gallons. And Honda’s best-selling compact car comes with an average gas tank capacity of 13.2 gallons for all five trim levels—from the base

model to the performance-oriented

model.

But in select markets, the 2015

Civic GX

runs on compressed natural gas with a fuel capacity of eight gallons.

How to check your 2015 Honda Civic’s gas tank size

Still not sure how many gallons your Civic’s gas tank can accommodate? Here are a few simple ways to quickly figure it out:

Measure the gas tank

Ready to measure the volume of your gas tank all by yourself? Grab a measuring tape and a calculator, then simply multiply the width, length, and height of the tank. Next, you’ll just have to divide that number by 231 or the number of cubic inches in a gallon.

Check your owner’s manual

Still have your Honda owner’s manual on hand? If so, then look up the phrase “gas tank capacity” or something similar in the table of contents or index of the owner’s manual to verify the size of your fuel tank.

Drive till empty, then fill it up

If the other two options don’t work for you and “danger” is your middle name, then you can simply determine your Civic’s gas tank size by driving until you reach the “E” on your fuel gauge. It might be a riskier method and you won’t get the most accurate measurement, but you’ll be able to figure out the general size of your gas tank. Just remember to quickly refill the gas tank on your Civic so it doesn’t stop in the middle of the road!

How to save on fuel costs in a Honda Civic

When powered by a modest 1.8-liter inline-4 engine and automatic transmission, the 2015 Honda Civic receives 30 mpg in the city and 39 mpg on the highway. But if you’re looking for more pep in your step, the 2.4-liter inline-4 engine delivers more power but sacrifices when it comes to fuel economy with 22 mpg in the city and 31 mpg on the highway.

While the Civic is known for its fuel efficiency, you still want to make sure you're getting the most for your money. If you’re looking to preserve gas and money, follow these hot tips:

Follow a maintenance schedule. Don’t let wear and tear go on for too long on your Civic! Otherwise, this can cause your fuel economy to decline.

Drive carefully. If you’re looking to conserve your fuel consumption, take it easy on the gas pedal and avoid accelerating too aggressively to keep costs down.

Don’t idle, especially when it’s cold. We know it can be tempting to warm up your vehicle on a cold winter morning, but idling will end up eating away at your gasoline.
