How to save on fuel costs in a Grand Cherokee

The 2018 Jeep Grand Cherokee has a fairly average fuel efficiency rating for an SUV of its size at 21 mpg combined city/highway. That gas mileage is the same across the board when it comes to trim level, so you won’t be able to benefit from a better fuel economy by choosing a different trim. 
If you’re dead set on a used Jeep or if you already own one, here are some tips and tricks to help keep your fuel consumption—and costs—as low as possible: 
  • Keep up with a basic
    car maintenance schedule
    . Allowing your Grand Cherokee to suffer extensive wear and tear can affect the minivan at every level, including fuel efficiency.
  • Drive carefully. Avoid harsh acceleration and riding the brakes to keep your SUV’s fuel consumption as steady (and low) as possible. 
  • Avoid idling, especially in cold weather. Leaving your ignition on while you’re not actually driving actively wastes fuel. It’s a better idea to grin and bear a few minutes of cold driving on a winter morning to let your Jeep warm up as opposed to letting it idle in the driveway.
