How many gallons does a 2018 Toyota Sequoia hold?
The 2018 Toyota Sequoia holds about 26.4 gallons of fuel in its tank (roughly 100 liters). This is the standard capacity for Sequoia models fitted with the 5.7-liter V8 engine that year.
Official capacity and its practical implications
Tank size matters for refueling planning and trip range, especially on long road trips or when towing. Toyota’s full-size Sequoia uses a relatively large tank to extend intervals between fills.
The following figures summarize the model’s official capacity, fuel economy, and estimated driving range.
- Fuel tank capacity: 26.4 US gallons (100 liters)
- EPA-estimated fuel economy (2018 Sequoia with 5.7L V8): 13 mpg city / 17 mpg highway / 15 mpg combined
- Estimated driving range on a full tank: about 343 miles in the city, 449 miles on the highway, and 396 miles combined
Note: Real-world range varies with driving conditions, payload, terrain, climate control use, and driving style. The figures above reflect EPA estimates and typical performance for the 2018 Sequoia.
Practical considerations for owners and buyers
While the capacity is consistent across 2018 Sequoia trims, actual range will depend on how the vehicle is used. For planning long trips or towing, it's wise to monitor fuel economy and carry a buffer for unexpected detours.
Summary
The 2018 Sequoia’s tank holds 26.4 gallons, with EPA ratings around 13/17/15 mpg, giving an approximate range of 343 miles in city driving, 449 miles on the highway, and 396 miles overall.
