Toyota 4Runner data analysis
Fuel tank: 23 gallons
The Toyota 4Runner holds 23 gallons (Standard). Smaller-tank configurations carry 19 gal — 4 gal less, and on a long drive that is a whole extra stop. That is rank 16 of 51 vehicle we hold tank data fors in this dataset, 70th percentile. The cohort median is 21 gal, so this vehicle sits 2 gal above the middle of the field. Next rung up is the Dodge Durango at 24.6 gal, 1.6 gal clear of this one. Immediately behind: the Jeep Wrangler at 22.5 gal. Ford F-150 matches it exactly — that figure is a segment convention, not an engineering ceiling.
How far that goes
Full-tank range works out at 391–529 miles on EPA combined figures (17–23 MPG across the configurations on file). On the highway cycle at 26 MPG the best version covers 598 miles between fills. Treat 352 miles as the working number. Cold weather, roof loads and a 75 mph cruise each cost 10–20% against the EPA figure. Annual fuel spend at 15,000 miles and $3.50/gal: $2,283, across about 28 tanks.
Configurations and caveats
12 configurations on file across 2015–2026. Four-wheel-drive versions occasionally carry a smaller tank than two-wheel-drive ones to clear the transfer case, so match the row to the drivetrain. Sources for these 12 rows: manufacturer filings, covering 12 model years.
How Toyota 4Runner fuel tank capacity varies
Across 12 configurations recorded for the 2015 through 2026 Toyota 4Runner, fuel tank capacity runs from 19 gallons to 23 gallons. The strongest figure belongs to the 2015 Toyota 4Runner (Standard) at 23 gallons, and the weakest to the 2026 car (Standard) at 19 gallons — a spread of 21%. A gap that wide means the model year and configuration you buy matter more than the nameplate does: quoting a single number for the Toyota 4Runner would be misleading.
What changed for 2026
Average fuel tank capacity for the 2026 Toyota 4Runner is 19 gallons, against 19 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.
Configurations behind these Toyota 4Runner numbers
The 2015 through 2026 Toyota 4Runner 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.
