Typical fuel economy for a 2002 Yukon XL with a 5.3-liter V8 sits around 15 miles per gallon combined, with roughly 13–15 mpg in city driving and 18–21 mpg on highways, varying by drivetrain and conditions.
The 2002 Yukon XL is a full-size SUV used for family hauling and towing, and MPG depends on whether the model is 2WD or 4WD, the transmission, and how it’s maintained. This article outlines typical ranges and factors that influence real-world fuel economy.
Typical MPG ranges by drivetrain
2WD vs 4WD differences
Before listing the numbers, note that actual mileage can vary widely based on load, terrain, and maintenance. The following ranges reflect common estimates from EPA-era data and owner reports for the 5.3L V8 in the Yukon XL.
- 2WD (rear-wheel drive) with a 5.3L V8: roughly 14–16 mpg city and 19–21 mpg highway (about 17–18 mpg combined).
- 4WD (four-wheel drive) with a 5.3L V8: roughly 13–15 mpg city and 18–20 mpg highway (about 15–17 mpg combined).
These ranges capture typical performance across models from the era, but real-world numbers depend on factors such as tire choice, payload, towing, and maintenance.
Factors that influence MPG on this model
Understanding what pushes MPG up or down helps explain the spread in numbers you may see in practice. The main drivers include:
- Payload and towing weight
- Tire size, tread, and rolling resistance
- Engine and transmission maintenance (spark plugs, air filter, oxygen sensors, etc.)
- Driving style and terrain (highway cruising vs. city stop-and-go)
- Overall vehicle age, wear, and fuel-quality effects
By keeping up with maintenance, choosing appropriate tires, and moderating loads, you can maximize economy within the vehicle’s design limits.
Summary
The 2002 Yukon XL with a 5.3L V8 typically delivers about 15 mpg combined, with 13–15 mpg in city driving and 18–21 mpg on highways for 2WD models, and roughly 13–15 mpg city / 18–20 mpg highway for 4WD models. Real-world numbers vary based on drivetrain, maintenance, payload, and driving conditions. For the most accurate figure, consult the vehicle’s owner manual, check the VIN-specific EPA data, or review owner-reported tests for the exact configuration.
