How to save on fuel costs in a Liberty
While you might be able to find the same size engine and gas tank in all of the 2012 Jeep Liberty trims, each model is available with either two-wheel drive or four-wheel drive. This has no bearing on the size of the Liberty’s gas tank; however, it does affect how the SUV consumes fuel.
Let’s take a closer look at the fuel efficiency across the 2012 Liberty lineup to determine how far each drivetrain option can run on a full tank of gas.
Model | Engine | Drivetrain | Fuel economy | Maximum range on a full tank |
|---|---|---|---|---|
2012 Jeep Liberty | 3.7-liter V6 | Two-wheel drive | 18 mpg combined | 351 miles |
2012 Jeep Liberty | 3.7-liter V6 | Four-wheel drive | 17 mpg combined | 331.5 miles |

The 20-mile range difference between the 2WD Liberty and the 4WD Liberty might not seem like that big of a deal, but it does mean that you’ll be saving essentially a gallon’s worth of gas on each full tank when you drive a two-wheel drive model.
That said, some drivers—like those who live and drive in snowy climates—might not be able to sacrifice their Jeep’s four-wheel-drive capabilities to save so little on fuel costs. So, here are some additional tips and tricks to help keep your fuel consumption as low as possible:
- Keep up with maintenance. Regular maintenance can halt developing issues in their tracks. Not only will this save you money on repair costs, but it can also save you money on gas if those issues impact the SUV’s fuel efficiency.
- Drive carefully. Riding the brakes or flooring the accelerator in your Liberty is the perfect way to run through fuel more quickly than you need to. Using a gentle foot can help to keep your SUV’s fuel consumption as steady (and low) as possible.
- Avoid idling. Idling engines are horrible for gas consumption. Avoid leaving your engine on while your car is parked, even in the winter, to avoid wasting valuable fuel.
