The gas tank size in your Kia Niro depends on its trim and model options. Most Niros have a gas tank size of 11.9 gallons. However, the plug-in hybrid (PHEV) Niros have a fuel tank capacity of 11.4 gallons. 
You’re unlikely to overfill your gas tank due to the design of modern fuel pumps. But whether you’re going on a road trip or calculating your monthly expenses, your car’s gas tank size is valuable knowledge. 
Your vehicle owner’s manual will explain the fuel tank size, but if you’ve lost the manual, don’t worry.

How to check your Kia Niro’s gas tank size

If you want a little more reassurance and like to verify things yourself, you can use three easy methods to check your car’s gas tank size. 

Measure the tank

If you don’t mind tight spaces or getting your hands dirty, this first method is for you. You can measure your gas tank, and the only tools you’ll need are a calculator and a measuring tape.
Crawl beneath your car and take the tank’s measurements. Multiply its width, height, and length. Then, divide this number by 231 (the number of cubic inches in a gallon) to determine your Niro’s gas tank size in gallons.

Check your owner’s manual

Alternatively, you can learn your Niro’s gas tank size by checking the owner’s manual. You can generally find this information under a label like “fuel tank capacity” or something similar. 

Drive until empty, then fill it up

Don’t have an owner’s manual and prefer driving to crawling under the car? Well, there’s one final method you can try—but it requires a bit of white-knuckling.
For this tactic, drive your car until the gas gauge reaches empty. Ideally, you should plan in advance and try to end near a gas station because the next step is to fill the tank.
Remember to note down how many gallons of gas you add to the car. This number won’t be exact, but it will be close enough.

How to save on fuel costs in a Kia Niro

The Kia Niro is excellent for fuel economy. Even the lowest achievers of the Niro line get more than 40 MPGs combined on city and highway, while some of the plug-in hybrids can achieve more than 100 MPGs combined mileage. 
No matter how great your fuel efficiency is, saving money at the pump never hurts. If you’re interested in learning how you can increase your fuel economy, follow these tips:
  • Drive your Niro conservatively. You might be wasting gas if you’re in the habit of taking off too quickly when leaving an intersection or stop sign. Slow down, especially when accelerating, to increase your fuel efficiency.
  • Don’t skip routine maintenance. Regular vehicle use adds wear and tear to your car. You can protect your car and increase your fuel efficiency by keeping up on regular maintenance, like oil changes and tire rotations.
  • Don’t leave your car idling for long periods, especially during the winter. Allowing your vehicle to idle for an extended amount of time is sure to waste your fuel. Try warming your car up by driving it gently during the winter instead of idling.
