2021 Jeep Grand Cherokee’s 24.6-Gallon Gas Tank: Size, MPG & Range

2021 Jeep Grand Cherokee's 24.6-Gallon Gas Tank

Are you wondering how far you can go on a tank of gas in the 2021 Jeep Grand Cherokee? With gas prices fluctuating, it’s important to understand your vehicle’s fuel tank size, fuel economy, and driving range. The Jeep Grand Cherokee is a popular SUV choice that offers great capability both on and off the road. In this article, we’ll break down the Jeep Grand Cherokee gas tank size, MPG, and range so you can maximize every drop of gas.

An Overview of the Jeep Grand Cherokee Gas Tank Specs

The 2021 Jeep Grand Cherokee comes equipped with a 24.6-gallon fuel tank. This gas tank size is quite large compared to other midsize SUVs. For example, the Honda Passport has a 19.5-gallon tank and the Hyundai Santa Fe has an 18.8-gallon tank. Having a generously sized 24.6-gallon fuel tank means you can go longer between fill ups.

It’s important to note that gas tank size can vary slightly between different Jeep Grand Cherokee models and trim levels. However, most 2021 variants have the 24.6-gallon capacity. The fuel tank uses regular unleaded gasoline.

Jeep Grand Cherokee MPG Ranges from 17 City to 26 Highway

With a 24.6-gallon gas tank, your potential driving range depends heavily on the Jeep Grand Cherokee’s fuel economy. For 2021 models, MPG ranges from:

  • 17 MPG city / 26 MPG highway with the 5.7L V8 engine
  • 19 MPG city / 26 MPG highway with the 3.6L V6 engine (standard)
  • 50 MPGe with electric motor for the 4xe plug-in hybrid

As you can see, factors like engine size, cylinders, and powertrain make a big impact on MPG. Going with the standard 3.6L V6 offers a nice balance of power and efficiency. The available 5.7L V8 sacrifices some fuel economy for much stronger performance and towing capabilities.

Driving Range Per Tank of Gas

So how far can you actually drive on single tank of gas in the Jeep Grand Cherokee? Here are some estimates:

  • 3.6L V6: Approximately 520 miles per tank (24.6 gallons x 19 MPG city x 75% city driving)
  • 5.7L V8: Approximately 450 miles per tank (24.6 gallons x 17 MPG city x 75% city driving)

Keep in mind these ranges are based on combined city and highway driving. You may be able to stretch it further with all highway miles. The 4xe plug-in hybrid also offers up to 25 miles of all-electric driving before tapping into the gas tank.

No matter which Grand Cherokee you choose, the 24.6-gallon tank gives you plenty of fuel for long trips between fill-ups. Very few competitors can match this kind of driving range.

Other Factors That Affect Jeep Grand Cherokee Gas Mileage

While EPA estimates provide a useful benchmark, real-world MPG depends on several factors:

  • Driving style: Aggressive acceleration and braking hurts MPG. Gentle driving improves it.
  • Towing or hauling: Adding more weight strains the engine, reducing fuel economy.
  • Climate and regional terrain: MPG tends to dip in very cold weather or mountainous regions.
  • Vehicle maintenance: Issues like underinflated tires, dirty air filters, old spark plugs can sap MPG.
  • Aftermarket modifications: Certain modifications like lift kits hurt aerodynamics and fuel efficiency.

Keeping these variables in mind helps you make realistic MPG predictions and range calculations. Checking your real-world fuel usage helps refine your gas budget.

Tips to Improve Jeep Grand Cherokee Gas Mileage

While fuel economy ultimately depends on your specific Grand Cherokee configuration, here are some tips to optimize MPG:

  • Stick to the speed limit – Wind resistance increases exponentially above 50 mph.
  • Plan ahead to minimize stops – Accelerating from a dead stop hampers efficiency.
  • Go easy on the pedals – Gentle acceleration and braking helps use less fuel.
  • Remove extra weight – Clear out unnecessary cargo for best MPG.
  • Keep tires properly inflated – Underinflation causes more rolling resistance.
  • Use recommended engine oil – Helps the engine operate at peak efficiency.
  • Stay on top of maintenance – Fixing issues quickly improves MPG.
  • Limit idling – Shut off your engine if stopped for more than 60 seconds.

Following these gas mileage best practices makes the most of every gallon, no matter which Jeep Grand Cherokee configuration you choose.
