Nissan Pathfinder data analysis
How Nissan Pathfinder fuel tank capacity varies
Across 12 configurations recorded for the 2015 through 2026 Nissan Pathfinder, fuel tank capacity runs from 18.5 gallons to 19.5 gallons. The strongest figure belongs to the 2015 Nissan Pathfinder (Standard) at 19.5 gallons, and the weakest to the 2026 car (Standard) at 18.5 gallons — a spread of 5%. The narrow spread means any year of the Nissan Pathfinder in this table behaves much like the others, so you can shop on price, condition and mileage rather than chasing a particular model year.
What changed for 2026
Average fuel tank capacity for the 2026 Nissan Pathfinder is 18.5 gallons, against 18.5 gallons for the 2025 car — it held flat. A carry-over year like this usually means no powertrain or structural change, so an older example is the cheaper way into the same specification.
How to read this Nissan Pathfinder data
This page lists every 2015 through 2026 Nissan Pathfinder record we hold for this measurement — 12 rows in total, one per configuration and model year rather than a single headline figure. Figures are published as the source agency records them: we do not round, average or interpolate missing years, and a year that is absent from the table is a year with no published measurement rather than a zero. Where a manufacturer offered several drivetrains or body styles in the same year, each appears on its own row, because those variants rarely share the same numbers.
Configurations behind these Nissan Pathfinder numbers
The 2015 through 2026 Nissan Pathfinder entries here span 12 model years of published measurements for this figure. 2026 is the busiest model year in the record with 1 separate measured configuration, which is why a single quoted fuel tank capacity figure for that year is rarely the one that matches the car in front of you. Match the row to the exact drivetrain, body style and engine on the window sticker or VIN before relying on the number, and use the comparison links below to see how those same configurations line up against rival models.
Where these Nissan Pathfinder figures come from
Every value on this page is loaded from federal open data — EPA fuel economy submissions, NHTSA vehicle and crash-test records, and manufacturer specification filings — rather than dealer listings or copied editorial content. The Nissan Pathfinder record refreshes as the agencies publish, which typically means new model-year rows appear in the autumn and crash-test results follow through the model year as vehicles are tested. Because certification data is filed per configuration, treat any single headline number for this vehicle with caution: the figure that applies to a specific car depends on its engine, drivetrain, body style and model year, all of which are listed separately above. If a number here disagrees with a brochure, the brochure is usually quoting the best available configuration rather than the one being sold.
