Practical considerations and range
With a 21-gallon tank, driving range is largely determined by fuel economy, driving conditions, and drivetrain (2WD vs. 4WD). While engine choices differ in efficiency and performance, the storage capacity itself remains constant, providing a substantial buffer for highway cruising and mixed-use trips. Always refer to the exact specification for your vehicle if you have a specific VIN or trim level, since manufacturing tolerances and regional variations can influence usable capacity slightly.
