How big is the gas tank on a 2019 Nissan Frontier?

Your fuel tank capacity, or the volume of fuel that can be pumped into your 2019 Nissan Frontier’s gas tank, is 21.1 gallons or 80 liters
This number remains consistent across all S, SV, SL, Desert Runner, and Pro 4X trim levels. 

How to check your 2019 Nissan Frontier’s gas tank size

If you can’t remember your fuel tank size or need to check the capacity yourself, there are a few different ways you can find out how much fuel your Frontier holds.

Measure the gas tank

To measure the volume of your fuel tank, measure the height, width, and length of the tank using a measuring tape. 
Once you have all three measurements, multiply the numbers together and divide them by 231 (the number of cubic inches in a gallon). The resulting number is the size of your fuel tank!

Check your owner’s manual

If you still have your hands on your vehicle’s owner’s manual, you can look up your gas tank specs under “fuel tank capacity” or a similar phrase.

Drive till empty, then fill it up

In some cases, you’ll find out the size of your fuel tank simply by running out of fuel. While this form of measurement is riskier and less precise than others, you’ll have a good idea of how long your vehicle can run once you hit “E.” 
Just don't let your vehicle run on empty for too long!

How to save on fuel costs in a Nissan Frontier

With a regular gasoline engine and rear-wheel drivetrain, the 2019 Nissan Frontier has a 19 mpg combined city/highway rating
To put this number in perspective, any vehicle with an unadjusted combined fuel economy less than 22 mpg is subject to the
US Gas Guzzler Tax
—meaning that the Nissan Frontier is not fuel-efficient. 
Luckily, there are simple steps you can take to improve or at least maximize the fuel efficiency in your Frontier, including: 
  • Regular vehicle maintenance. Keeping up with your Nissan’s maintenance will prevent unnecessary wear and tear and ensure your fuel economy stays consistent over time. 
  • Drive at a steady speed. Avoid unnecessary, harsh accelerations or decelerations on the road.
  • Avoid long periods of idling. Idling is a major waste of fuel, so avoid letting your Frontier run in cold weather for long periods before hitting the road.
