How big is the 2025 Honda Pilot gas tank?
The gas tank capacity of the 2025 Honda Pilot is 19.5 gallons (approximately 74 liters).
The 2025 Pilot uses a single, standard fuel-tank size across its trims, and Honda has not announced a larger or smaller tank option for this model year. The tank size, paired with the SUV’s fuel economy, determines the driving range you can expect on a full tank.
Tank capacity and driving range
With a 19.5-gallon tank, the Pilot’s driving range depends on the vehicle’s miles-per-gallon (mpg) rating. The Pilot’s EPA-estimated mpg is typically in the low-to-mid 20s combined, varying by drivetrain (2WD vs. AWD) and trim. This yields a rough full-tank range in the neighborhood of about 400 to 500 miles under typical mixed driving conditions.
Drivetrain impact on efficiency
Two-wheel-drive versions generally deliver slightly better mpg than all-wheel-drive versions, which in turn affects the total miles you can travel on a full tank. Regardless, the 19.5-gallon tank remains the same across configurations.
Why this matters for buyers
Knowing the tank size helps plan long trips and fuel stops, especially on highway-heavy routes. If you expect to drive mainly highway miles, you’ll likely approach the upper end of the estimated range; in more urban driving, the range may be closer to the lower end.
Summary
In short, the 2025 Honda Pilot carries a 19.5-gallon gas tank (about 74 liters), a capacity that is consistent across trims and is the main factor shaping its practical range between refills. Expect roughly 400–500 miles per tank depending on driving style and conditions.
