Official fuel-tank specifications
Here are the core figures Toyota published for the 2014 Sienna, including the popular XLE grade.
- Fuel tank capacity: 18.0 gallons (68 liters)
- Fuel type: Regular unleaded gasoline
- Applicable to: 2014 Sienna with 3.5L V6 engine, including the XLE trim
In short, the Sienna’s tank holds 18.0 gallons of regular unleaded fuel, a capacity designed to balance range with the vehicle’s performance and cargo space.
Estimating your driving range
To translate that tank size into practical distance, use your vehicle’s miles-per-gallon (mpg) figures. Multiply the mpg by the 18.0-gallon tank to estimate a driving range.
- Step 1: Determine your average fuel economy (mpg) for typical driving, using the on-board computer or EPA estimates for the model year with your drivetrain.
- Step 2: Multiply your mpg by 18.0 gallons to estimate the potential range in miles.
- Step 3: Adjust downward for real-world conditions such as heavy acceleration, cargo load, driving in hilly terrain, or use of all-wheel drive.
Use this method for a rough estimate; actual range will vary with traffic, climate control use, terrain, and tire condition.
Real-world range considerations
While 18.0 gallons is a fixed capacity, actual range depends on driving style, vehicle load, and environmental factors. If you rely on a single long journey, plan for a buffer and know that highway cruising typically yields higher mpg than city driving.
Summary
The 2014 Toyota Sienna XLE is equipped with an 18.0-gallon fuel tank (approximately 68 liters). This fixed capacity, combined with the vehicle’s fuel economy, determines how far you can travel on a full tank. For precise range, consult your specific EPA ratings or on-board computer data and account for your typical driving conditions.
