Aerodynamics and Vehicle Weight
While Grand Cherokee dimensions are generally similar across recent models, factors like roof racks or aftermarket accessories can affect aerodynamics. The overall weight of the vehicle, including passengers and cargo, also plays a role.
Calculating Your Grand Cherokee’s Driving Range
The Jeep Grand Cherokee fuel tank capacity directly influences how far you can drive before needing to refuel. Your driving range is calculated by multiplying your fuel tank capacity by your average MPG:
Driving Range = Fuel Tank Capacity (gallons) × Average MPG
Let’s look at some hypothetical examples to illustrate this:
- Scenario 1: 24.6-gallon tank with 22 MPG combined:
Range = 24.6 gallons × 22 MPG = 541.2 miles - Scenario 2: 24.6-gallon tank with 18 MPG combined (e.g., with a V8 or in city driving):
Range = 24.6 gallons × 18 MPG = 442.8 miles - Scenario 3: 20.0-gallon tank with 20 MPG combined (e.g., an older model):
Range = 20.0 gallons × 20 MPG = 400 miles
These are estimates, and your actual range can vary. It’s always wise to refuel when the gauge indicates around a quarter of a tank remaining to avoid running on fumes.
Key Features of the Jeep Grand Cherokee Fuel System
Beyond the sheer volume, the Jeep Grand Cherokee fuel tank is designed with several features to ensure performance, safety, and convenience.
Fuel Tank Material and Design
Modern fuel tanks are typically made from high-density polyethylene (HDPE). This plastic material is lightweight, durable, corrosion-resistant, and helps reduce evaporative emissions compared to metal tanks. The Grand Cherokee gas tank size and shape are engineered to fit optimally within the vehicle’s chassis, often positioned for better weight distribution and protection.
Fuel Pump Module
The fuel pump is housed within the fuel tank and is responsible for delivering fuel from the tank to the engine. The fuel pump module typically includes the pump itself, a fuel level sender (which informs the dashboard gauge), and a fuel filter.
Evaporative Emission Control (EVAP) System
To comply with environmental regulations, the Grand Cherokee is equipped with an EVAP system. This system captures fuel vapors from the tank and reroutes them to be burned in the engine, preventing them from escaping into the atmosphere.
Fuel Cap and Filler Neck
A properly sealing fuel cap is essential for the EVAP system to function correctly. The filler neck is designed for easy and safe refueling. Some models may feature a capless fueling system for added convenience.
