Most Toyota 4Runner models use a 23-gallon (87-liter) fuel tank. Exact capacity can vary by year and trim.
In practice, 23 gallons is the standard figure for the modern 4Runner, especially in the fifth generation (2009–present). Some older or special-edition models may have slightly different sizes, so it’s best to verify your vehicle’s exact specification through official documentation or the door placard.
What you should know about the tank size
Before diving into specifics, here are the core facts about 4Runner fuel tanks.
- Typical capacity: 23 gallons (87 liters) for most modern 4Runners.
- Possible variations: A small number of older or niche configurations may use a different capacity.
- Practical range: With common fuel economy, a full tank provides hundreds of miles of driving (roughly 400–500 miles, depending on engine, drivetrain, and conditions).
Note that the exact figure for your vehicle should be confirmed via the owner’s manual, the fuel door placard, or Toyota’s official specifications for your model year and trim.
How to confirm your exact tank size
To verify your vehicle’s precise capacity, check the owner’s manual, inspect the fuel-filler door placard, or look up the official specifications for your model year and VIN on Toyota’s site or in the dealer literature. A quick call to a Toyota dealer can also confirm the exact figure for your specific 4Runner.
Summary
In short, the typical gas tank on a 4Runner is 23 gallons (87 liters). Always verify for your exact model year and trim to account for any variations.
