The 2020 Toyota 4Runner uses a 23-gallon fuel tank (about 87 liters).
In 2020, Toyota kept the 4Runner’s fuel capacity stable across trims. This tank size influences how far you can travel between fills, whether you’re highway cruising or navigating off-road terrain. The following figures provide a quick reference for the tank’s capacity and its metric conversion.
Fuel tank capacity in numbers
Before listing the numerical figures, here’s a quick reference of the tank’s capacity in common units and a note on drivetrain consistency:
- Gallons: 23 gal
- Liters: approximately 87 L
- Drivetrain and engine: Standard across 2020 4Runner models with the 4.0-liter V6, including both 2WD and 4WD configurations
In short, all 2020 4Runner models share the same 23-gallon tank, so fueling needs and range are consistent across trims.
Additional context
Impact on range and fueling schedule
With a 23-gallon tank, drivers can expect a substantial driving range, particularly when paired with the 4Runner’s V6 engine. Real-world range depends on driving conditions, payload, and use of four-wheel drive, but the tank size is designed to balance capacity with vehicle weight and off-road capability.
Summary
In short, the 2020 Toyota 4Runner comes with a 23-gallon fuel tank, equivalent to about 87 liters, a capacity shared by all trims of that model year.
