How to check your 2008 Jeep Liberty’s gas tank size

If you ever find yourself in a position where you need to figure out your fuel tank capacity all by yourself, don’t worry—there are a few tried-and-true methods for doing so. 

Measure the gas tank

Get out a measuring tape and remember the following equation: width times length times height, all divided by 231—the number of cubic inches in a gallon. 

Check your owner’s manual

Your owner’s manual includes pretty much everything you need to know about your Jeep—including your fuel tank capacity. Head to the manual’s index and look for key terms like “gas tank” or “fuel tank.”

Drive till empty, then fill it up

This method is, admittedly, a little risky and not as accurate as the previous two options. However, it’s a good idea if you’re in a pinch!
Drive around until your car is on “E” for empty—then head to the gas station. Once you fill it all the way up, you can read the fuel pump for an estimate of your tank’s total capacity. 

How to save on fuel costs in a Jeep Liberty

The 2008 Jeep Liberty gets 16 mpg in the city and 22 mpg on the highway. Unfortunately, that’s not exactly fuel efficient.
There are a few ways to save on gas, however, by ensuring that your Liberty remains as efficient as possible:
  • Don’t skip out on maintenance. It can be easy to neglect routine maintenance on your Jeep, such as oil changes and tire rotations. If you’re concerned about saving gas, however, avoid getting lazy. Unnecessary wear and tear decrease your fuel economy significantly. 
  • Drive carefully. Don’t be a speed racer—instead, accelerate gently and carefully, keeping an eye on your RPM gauge, ensuring it never shoots up too high.
  • Avoid idling, especially in cold weather. Leaving your vehicle running without actually driving anywhere still wastes gas. Always turn your ignition off when your vehicle is not actively in motion.
