Jeep Cherokee Gas Tank Size, MPG, and Fuel Type for Your Needs

Are you considering buying a Jeep Cherokee but not sure what gas tank size, fuel efficiency, and gas type to choose? With so many options, it can be tricky to find the right specs for your needs. In this comprehensive guide, we’ll walk through everything you need to know about optimizing your Jeep Cherokee’s range and performance.

So Let’s start…

The Jeep Cherokee is one of the most popular compact SUVs on the market, known for its great balance of on-road comfort and off-road capability. With roots going back to the 1970s, Cherokees have long provided owners with rugged dependability.

But today’s Jeep Cherokee models offer much more refinement, technology, and efficiency than their predecessors. The latest Cherokees can accommodate busy families with ample cargo space, while also tackling rugged terrain on weekend getaways.

To get the most out of your new Cherokee, you’ll want to choose the gas tank size, miles per gallon (MPG), and fuel type that best fits your needs. The Cherokee offers versatile configurations to suit different drivers. Here’s what you need to consider:

Gas Tank Size: Cherokee tanks range from 15.8 to 24.6 gallons. The size affects your driving range between fill-ups.

MPG: Fuel efficiency varies from 22 to 31 MPG depending on engine and configuration. MPG impacts your overall operating costs.

Fuel Type: Most Cherokees use regular unleaded gasoline. Some performance models need premium fuel. The type affects performance and your gas budget.

Balancing these factors allows you to optimize for your priorities – whether that’s maximum range, efficiency, or power. We’ll explore all the options so you can make the best choice. Let’s dive in!

Jeep Cherokee Gas Tank Sizes

The total driving range available between fill-ups is determined largely by the size of the fuel tank. Jeep equips different Cherokee models with gas tanks ranging from 15.8 to 24.6 gallons.

Here are the most common tank sizes found in recent Cherokee models:

• 15.8 gallons – This smaller tank is typical on 4-cylinder Cherokee models aimed at improved fuel efficiency. The downside is less overall range, requiring more frequent fill-ups.
• 19.5 gallons – This mid-size tank hits a nice balance for V6 models. It minimizes weight while still allowing an average range per tank of 500+ miles.
• 24.6 gallons – Higher-end and performance Cherokees often include the largest 24.6 gallon tank. It provides 700+ miles between fill-ups for long trips or off-roading.

The choice ultimately comes down to your needs and priorities. The larger tank provides more convenience and versatility, while the smaller size may save money on fuel if your daily driving is limited.

Families or adventurers who value extended range between pit stops will want to opt for the 24.6 gallon upgrade. Commuters who rack up lower annual mileage may prefer the lighter weight and lower fill-up cost of the 15.8 gallon tank.

When planning far-flung camping or overlanding trips, keep in mind that gas stations can be few and far between in remote areas. The extra capacity of the large tank provides crucial peace of mind.

No matter which you choose, keeping an eye on your Cherokee’s fuel gauge is advised. Running your tank too low too often can cause sediment to clog components and reduce the pump’s lifespan.

Jeep Cherokee MPG and Fuel Efficiency

While tank size determines range, your Jeep Cherokee’s MPG rating gives you an estimate of how many miles you can drive on a gallon of gasoline. Higher MPG means lower fuel costs and fewer fill-ups required to travel the same distance.

Cherokee fuel economy ranges from 22 MPG combined (city/highway) for some V6 models, up to 31 MPG for the most efficient 4-cylinder variants.

Here are some key factors that affect MPG in the Cherokee:

• Engine size – 4-cylinder Cherokees achieve higher efficiency than the available V6.
• Drivetrain – Two-wheel drive models are typically more efficient than four-wheel drive.
• Transmission – Automatic transmissions now include more gears to optimize MPG.
• Trim level – Lower weight on basic models improves economy versus heavy luxury models.
• Driving style – Aggressive acceleration and high speeds reduce real-world MPG.

Your actual gas mileage will vary depending on how you drive and the conditions you face. For example, frequent stop-and-go traffic, sustained high speeds, and cold weather can all reduce MPG. Conscientious driving helps maximize your efficiency.

Some tips to improve MPG in your Cherokee:

• Accelerate gently from stops
• Avoid jackrabbit starts
• Plan ahead to minimize unnecessary braking
• Follow the speed limit – aerodynamic drag increases exponentially above 50 mph
• Run errands together to condense trips
• Remove excess cargo weight when not needed
• Check tire pressures monthly to reduce rolling resistance
• Use the air conditioner sparingly

Choosing a more efficient engine and drivetrain along with smart driving habits allows you to save money at the pump. For some owners, maximizing miles per gallon is a top priority.

Recommended Octane Rating and Gas Types for Jeep Cherokees

While most Cherokees run perfectly fine on regular 87 octane unleaded gasoline, some models call for or recommend premium 91 octane fuel for maximum performance:

• High-output V6 engines: Choosing 87 octane gas is acceptable, but Jeep recommends 91 octane to maximize horsepower and torque production in performance models.
• Turbocharged engines: Check your manual – many turbo models require premium fuel to prevent knocking or detonation under boost.
• Track/competition usage: Always use 91+ octane gas when pushing your Cherokee’s engine hard at high RPM on track days or off-road competitions.

The advantage of higher octane gasoline comes from its higher resistance to “knocking” or pre-detonation when subjected to heat and pressure during combustion. This allows engines to safely run more ignition timing advance for improved efficiency and power output.

The downsides of premium fuel are reduced availability at some gas stations and about a 20-30 cent per gallon price premium over regular gas. For most Cherokee drivers doing normal daily commutes or road trips, paying extra for 91+ octane gasoline offers minimal benefit.

But enthusiasts who frequently run their engine hard or modified engines making more power can gain an edge in performance from the higher quality fuel. Check your owner’s manual fuel requirements to be sure.

How Gas Tank Size, MPG, and Gas Type Interact in Your Jeep Cherokee?

On their own, gas tank capacity, fuel economy ratings, and fuel type give you part of the picture. But it’s understanding how they work together that helps optimize your Cherokee’s range and performance.

Large, thirsty engines straining under heavy loads need more frequent fill-ups. Conversely, smaller engines sipping fuel through city streets may safely use a smaller tank to reduce weight and cost.

Here are some examples of how real-world combinations might play out:

• A 4-cylinder Cherokee with 22 MPG combined and 15.8 gallon tank achieves approximately 350 miles between fill-ups. Saving weight with the smaller tank balances out the engine’s efficiency for city drivers.
• A V6 model with 19.5 gallon tank and 25 MPG combined can easily achieve 500 miles on a tank for longer road trips.
• An off-road focused V6 with low-range 4WD and heavy duty suspension may only manage 20 MPG combined – but the huge 24.6 gallon tank extends its range to 500 miles to handle remote trails.
• A high performance V6 requires premium gasoline to reach its potential. The extra cost is offset slightly by an efficient 25 MPG combined rating and 19.5 gallon tank.

As you can see, properly pairing the tank capacity, efficiency, and fuel requirements allows you to tailor your Cherokee for your needs. Keep your priorities in mind as you evaluate options.

Typical Gas Tank and MPG Needs for Different Jeep Cherokee Owners

With an understanding of the variables, we can look at how typical Jeep Cherokee owners can configure their vehicles based on their intended usage:

Commuter Vehicles

Drivers who log long rush hour highway miles need to maximize fuel economy. A 4-cylinder Cherokee with a smaller 15.8 gallon tank keeps weight down while achieving 30+ MPG on the highway. Range between fill-ups is less important than efficiency.

Family Haulers

Soccer moms and dads need a balance of cargo space, passenger room, performance and efficiency to handle busy family lifestyles. A mid-level V6 Cherokee with 19.5 gallon tank and 25 MPG combined has the versatility to handle daily errands and weekend road trips.

Off-Road Enthusiasts

Weekend warriors who hit the trails need maximum range between fill-ups when far from civilization. A rugged V6 Cherokee Trailhawk or Overland with 24.6 gallons of gas onboard and low-range 4WD capability provides the remoteness insurance they need. Efficiency takes a backseat to capacity.

Performance Fans

Horsepower junkies want strong acceleration and high octane gasoline to optimize performance at the cost of efficiency. These drivers are willing to pay extra at the pump and make more frequent fill-ups to enjoy neck-snapping torque and high RPM power.

Think about your priorities – whether that’s low operating costs, extended range, power delivery, or a balance of factors. With so many configurations, the Cherokee can be customized to suit your needs.

How Aftermarket Modifications Can Affect MPG and Range?

One advantage of the Jeep Cherokee’s popularity is the wide range of aftermarket modifications available. But certain upgrades can impact your gas mileage, while others help extend your vehicle’s range.

Larger off-road tires, lifted suspensions, skid plates, bumpers and other accessories add weight and increase aerodynamic drag – both hurting MPG. On the flip side, upgrading to a larger fuel tank immediately boosts your Cherokee’s cruising distance.

Here are some common modifications and their effects:

• Larger All-Terrain Tires – More rolling resistance reduces highway economy by 2-3 MPG
• 2-3 inch Suspension Lift – Alters aero and steering geometry for 1-2 MPG loss
• Steel Bumpers and Skid Plates – Added weight limits efficiency, but improves protection
• Roof Racks and Light Bars – Create aerodynamic drag at highway speeds lowering MPG
• Cold Air Intakes and Exhausts – Aftermarket air and exhaust can optimize power at a small MPG cost
• Fuel Tank Skid Plate – Protects an oversized auxiliary tank vulernable on trails
• Upgraded Fuel Tank (24.6+ gallons) – Immediately increases range between fill-ups

As with your original purchase decision, you’ll want to balance added capability against potential efficiency losses based on how you use your Cherokee. Your mods may be worth a slight MPG penalty for better off-road performance.
