The Exact 2020 Jeep Cherokee Gas Tank Size: What You Need to Know
When it comes to hitting the trails or embarking on a long road trip, knowing your vehicle’s fuel capacity is foundational. For the 2020 Jeep Cherokee, the gas tank size is a consistent figure across most trims, providing a solid foundation for range calculations.
Standard Capacity Across Trims
The
2020 Jeep Cherokee gas tank size
is uniformly 15.8 gallons (approximately 59.8 liters) for all trim levels. This includes the Latitude, Latitude Plus, Limited, Trailhawk, and Overland models. Whether you’re driving a front-wheel-drive daily commuter or a rugged Trailhawk ready for rock crawling, your primary fuel reservoir holds the same amount.
This standardization simplifies fuel planning, as you don’t need to cross-reference different capacities based on your specific Cherokee variant. It’s a good, practical size that balances daily usability with enough capacity for decent range.
Fuel Economy & Real-World Range Estimates
While the tank size is fixed, your actual range will vary significantly based on your engine, drivetrain, and driving habits. The 2020 Cherokee offered several engine options:
- 2.4L Tigershark MultiAir 2 I4: Generally offers around 22 MPG city / 31 MPG highway (FWD).
- 3.2L Pentastar V6: Typically provides about 20 MPG city / 29 MPG highway (FWD).
- 2.0L Turbo I4: Often rated around 23 MPG city / 31 MPG highway (FWD).
These figures are for front-wheel-drive (FWD) models. Opting for four-wheel-drive (4WD) or Active Drive Low (Trailhawk) systems will slightly reduce these numbers, especially in city driving or off-road conditions.
To estimate your range, simply multiply your tank capacity by your average MPG. For example, with a 15.8-gallon tank and an average of 25 MPG, you’re looking at a theoretical range of around 395 miles. However, always factor in a safety margin, especially when heading into remote areas. Never push your vehicle to the absolute limit of its range.
Fuel System Components and Maintenance for Your Cherokee
Understanding your fuel tank capacity is just one piece of the puzzle. The entire fuel system works in harmony to get that gasoline from the tank to your engine. Proper maintenance is key to ensuring reliability, efficiency, and longevity, especially for vehicles that see tough off-road conditions.
Understanding Your Fuel System
Your Jeep Cherokee’s fuel system is more complex than just a tank and a filler neck. It includes the fuel pump, fuel filter, fuel lines, fuel injectors, and various sensors. The fuel pump, typically located inside the fuel tank, pushes fuel through the lines to the engine. Along the way, the fuel filter cleans out impurities, preventing them from clogging injectors or damaging engine components.
The fuel injectors precisely spray fuel into the engine’s combustion chambers, controlled by the engine’s computer (ECU). All these parts need to be in top condition for your Cherokee to run efficiently and reliably.
Essential Fuel Filter & Pump Maintenance
The fuel filter is a critical component that often gets overlooked. Over time, it can become clogged with dirt, rust, and other contaminants from the fuel. A clogged fuel filter can lead to:
- Reduced engine performance
- Hesitation or sputtering during acceleration
- Difficulty starting the vehicle
- Increased strain on the fuel pump, potentially leading to premature failure
Check your owner’s manual for recommended fuel filter replacement intervals. For off-roaders who might encounter lower-quality fuel or more dust, more frequent checks and replacements might be wise. Replacing the fuel filter is a relatively straightforward DIY task for many, requiring basic tools and a careful approach to avoid fuel spills. Always relieve fuel system pressure before beginning work.
While the fuel pump is generally designed to last the life of the vehicle, poor fuel quality or a consistently low fuel level can put extra strain on it. Running your tank nearly empty frequently means the fuel pump is not fully submerged in fuel, which helps cool it. This can lead to overheating and premature wear. Try to refuel before your tank drops below a quarter full.
Extending Your Range: Tips for Better Fuel Efficiency
Knowing your 2020 Jeep Cherokee gas tank size is great, but getting the most miles out of every gallon is even better. Whether you’re trying to save money on daily commutes or stretch your fuel further on an epic overlanding trip, these tips will help.
Driving Habits for Optimal MPG
Your driving style has a huge impact on fuel consumption. Adopt these habits for better efficiency:
- Smooth Acceleration & Braking: Avoid rapid acceleration and hard braking. Gentle inputs are much more fuel-efficient.
- Maintain Steady Speeds: Use cruise control on highways to maintain a consistent speed. Fluctuations in speed burn more fuel.
- Anticipate Traffic: Look ahead to avoid unnecessary stops and starts. Coasting to a stoplight instead of rushing and braking hard saves fuel.
- Reduce Idling: If you’re going to be stopped for more than 30 seconds, it’s generally more fuel-efficient to turn off your engine.
- Obey Speed Limits: Fuel economy significantly decreases at speeds above 60 mph.
Vehicle Maintenance for Peak Performance
A well-maintained vehicle is an efficient vehicle. Don’t skip these crucial maintenance items:
- Tire Pressure: Properly inflated tires reduce rolling resistance. Check your tire pressure regularly, especially before long trips or off-road excursions.
- Regular Oil Changes: Fresh, clean oil reduces engine friction, improving efficiency. Follow your manufacturer’s recommended oil type and change intervals.
- Air Filter Replacement: A clogged engine air filter restricts airflow, forcing your engine to work harder and consume more fuel. Replace it as per your maintenance schedule, or more often if driving in dusty conditions.
- Spark Plugs: Worn spark plugs can lead to misfires and inefficient combustion. Replace them according to your service schedule.
- Wheel Alignment: Misaligned wheels create drag and reduce fuel economy. Get your alignment checked periodically.
Load Management for Off-Roaders
For off-road enthusiasts, how you pack your Cherokee can also affect fuel economy.
- Reduce Excess Weight: Remove any unnecessary gear from your vehicle, especially heavy items. More weight equals more fuel consumed.
- Aerodynamics Matter: Roof racks, cargo boxes, and other external accessories create drag, especially at highway speeds. Remove them when not in use.
- Smart Packing: Distribute weight evenly and keep the center of gravity low. This not only helps with fuel efficiency but also improves handling and safety on uneven terrain.
Off-Roading and Overlanding: Fuel Planning for Remote Adventures
The true test of your fuel capacity comes when you venture far from civilization. For off-roaders and overlanders, meticulous fuel planning is non-negotiable. Knowing your 2020 Jeep Cherokee gas tank size is just the beginning; you need to understand how to leverage it for safe, successful trips.
Calculating Your Fuel Needs
When planning an off-road trip, don’t rely on highway MPG figures. Off-roading, especially in challenging terrain, can drastically reduce your fuel economy. Factors like low-range gearing, steep climbs, soft sand, and mud will burn fuel much faster.
- Estimate Off-Road MPG: A good rule of thumb is to assume your off-road MPG will be 50-70% of your highway MPG, or even lower for extreme conditions. Track your actual fuel consumption on previous trips to get a more accurate number.
- Map Your Route: Use detailed maps or GPS with topographical data to identify potential fuel stops. Mark them clearly.
- Calculate Round Trip Distance: Don’t forget the return journey! Always calculate the total distance.
- Add a Safety Margin: Always carry extra fuel. A 25-30% buffer is a good starting point, accounting for unexpected detours, getting stuck, or assisting another vehicle. Running out of fuel in the backcountry is dangerous and can quickly turn a fun trip into an emergency.
Safe Auxiliary Fuel Storage Options
For extended trips beyond the range of your 2020 Jeep Cherokee gas tank size, auxiliary fuel is essential. However, storing fuel requires careful consideration:
- Jerry Cans: High-quality metal or plastic jerry cans (like RotopaX or NATO-spec cans) are standard. Ensure they are specifically designed for fuel storage and meet safety standards.
- Mounting: Securely mount jerry cans outside the vehicle, if possible. Roof racks or rear bumper carriers are ideal. Never store fuel inside the passenger compartment due to fumes and fire risk.
- Ventilation: Ensure good ventilation around stored fuel to prevent pressure buildup.
- Spill Prevention: Carry a funnel and absorbent pads for refueling. Fuel spills in nature are harmful and should be avoided at all costs.
Remember, fuel is flammable. Handle it with extreme care, away from open flames, sparks, and hot engine components.
Navigating Remote Fuel Stops
In remote areas, gas stations might be few and far between, or they might not offer premium fuel.
- Confirm Availability: Call ahead or check online resources (like iOverlander) for fuel station operating hours and fuel types.
- Carry a Fuel Filter Funnel: A funnel with a built-in filter can help remove water and debris from questionable fuel sources.
- Have Backup Payment: Some remote stations might only accept cash or specific cards.
If you find yourself in a truly remote area with limited fuel, conserve every drop. Drive slowly, avoid aggressive maneuvers, and minimize idling. In extreme situations, consider contacting local park rangers or experienced guides for advice or assistance.
Common Fuel System Issues and Troubleshooting
Even with the best intentions and maintenance, issues can arise. Knowing how to diagnose and potentially troubleshoot common fuel system problems can save you a headache and keep you moving.
Warning Lights and What They Mean
Your Cherokee’s dashboard is your first line of defense against problems.
- Check Engine Light: This universal warning can indicate a wide range of issues, including fuel system problems like a loose gas cap, a failing oxygen sensor, or a clogged catalytic converter. Get the codes read with an OBD-II scanner to pinpoint the problem.
- Low Fuel Light: This is a clear indicator to refuel. Don’t ignore it, as consistently running on fumes can damage your fuel pump.
- Fuel Cap Light: If your gas cap isn’t properly sealed, this light might illuminate. Ensure it’s tightened until it clicks. A loose cap can also trigger a “Check Engine” light due to evaporative emissions system (EVAP) leaks.
Dealing with Fuel Contamination
Contaminated fuel (water, dirt, or incorrect fuel type) can wreak havoc on your fuel system.
- Symptoms: Rough idling, misfires, loss of power, or stalling.
- Action: If you suspect contaminated fuel, stop driving immediately. Continuing to drive can damage fuel injectors, the fuel pump, and other components.
- Solution: You’ll likely need to have the fuel tank drained, the fuel lines flushed, and the fuel filter replaced. This is often a job for a professional mechanic.
When to Seek Professional Help
While some minor issues can be DIY, certain problems warrant professional attention.
- Persistent Check Engine Light: After basic troubleshooting (like checking the gas cap), if the light remains, a diagnostic scan by a mechanic is necessary.
- Fuel Leaks: Any sign of a fuel leak (smell of gasoline, visible drips) is a serious fire hazard. Do not drive the vehicle; have it towed to a repair shop immediately.
- Fuel Pump Failure: Symptoms like the engine cranking but not starting, or a sudden loss of power while driving, could indicate a failing fuel pump. This is a complex repair best left to professionals.
