How Many Gallons In A Jeep Grand Cherokee
If you drive a Jeep Grand Cherokee or are thinking of buying one, you probably want to know about its gas tank size. This one detail can shape your driving habits, road trip plans, and even your monthly budget. But the answer is not the same for every Grand Cherokee. Over the years, Jeep has offered different gas tank sizes, depending on the model year, trim, and engine. In this article, you’ll find clear answers, useful comparisons, and practical tips for getting the most from your Grand Cherokee’s fuel tank.
Standard Fuel Tank Sizes By Year
The Jeep Grand Cherokee has been around since 1992, and its fuel tank capacity has changed with each new generation. Let’s look at the most common gas tank sizes by model year.
| Model Year | Fuel Tank Size (Gallons) |
|---|---|
| 1993–1998 | 23.0 |
| 1999–2004 | 20.5 |
| 2005–2010 | 21.6 |
| 2011–2021 | 24.6 |
| 2022–Present | 23.0–24.6 |
For most drivers, the 21 to 25-gallon range is typical. However, there are exceptions based on trim and engine choices.
Fuel Tank Differences By Trim And Engine
Not every Grand Cherokee has the same tank, even in the same year. Higher-performance engines or special trims may have a slightly larger or smaller tank. Here are some examples:
- The Trailhawk and Overland trims often use the standard tank size for their year.
- The SRT and Trackhawk (high-performance trims) usually come with a 24.6-gallon tank.
- Diesel models sometimes have a different, often slightly smaller, tank.
Let’s compare a few trims from a recent year:
| 2021 Trim | Engine Type | Fuel Tank Size (Gallons) |
|---|---|---|
| Laredo | V6 Gas | 24.6 |
| Limited | V6 Gas | 24.6 |
| SRT | V8 Gas | 24.6 |
| Diesel (past years) | V6 Diesel | 24.6 (varies) |
A non-obvious detail: Plug-in hybrid Grand Cherokees (like the 4xe) have a smaller gas tank, usually around 19.0 gallons, because some space is used for the battery.
How Far Can You Go On A Full Tank?
Knowing how many gallons fit in your Jeep Grand Cherokee is just the start. The real question: How far can you drive before refueling? This depends on your engine and how you drive.
Let’s see some average ranges:
| Engine | MPG (City/Highway) | Tank Size (Gallons) | Max Range (Miles) |
|---|---|---|---|
| V6 Gas | 19 / 26 | 24.6 | Approx. 467–640 |
| V8 Gas | 14 / 22 | 24.6 | Approx. 344–541 |
| Diesel | 21 / 28 | 24.6 | Approx. 516–688 |
| 4xe Plug-In Hybrid | 23 / 24 | 19.0 | Approx. 437–456 (+ electric range) |
A key insight: Your real-world range can drop if you have a heavy right foot, tow a trailer, or drive in the mountains. Cold weather also lowers fuel efficiency.
Why Fuel Tank Size Matters
A larger gas tank means fewer stops on long trips. If you drive in remote areas or use your Grand Cherokee for towing, a bigger tank offers peace of mind. But there’s a trade-off: a full tank adds weight. More weight can slightly lower your miles per gallon (MPG).
Some drivers are surprised that filling up when the needle is near empty still leaves some fuel in the tank. Most tanks have a “reserve” of about 1-2 gallons to keep the engine from running dry. It’s best not to make a habit of running your Jeep down to zero, as this can damage the fuel pump.
How To Find Your Exact Fuel Tank Size
If you want to be sure about your Grand Cherokee’s gas tank:
- Check your owner’s manual. The manual lists the exact tank capacity.
- Look for the sticker inside the fuel door. Many Jeeps show the size here.
- Search your VIN online. The Vehicle Identification Number can confirm details for your specific Jeep.
- Ask your dealer. Dealers can give you the exact number, especially for rare trims.
If you ever replace your tank or buy used, always double-check. Aftermarket or custom tanks may have different sizes.
Tips For Maximizing Your Driving Range
To get the most out of your fuel tank:
- Drive smoothly. Quick starts and stops lower your MPG.
- Keep tires properly inflated. Low pressure means more fuel burned.
- Remove extra weight. Don’t carry heavy items you don’t need.
- Keep up with maintenance. Clean air filters and timely oil changes help efficiency.
- Plan your routes. Avoid traffic jams and rough backroads when possible.
Many drivers miss the impact of roof racks and cargo boxes. These can lower your MPG by up to 10%, which means fewer miles per tank. Remove them when not in use.
