Is the Sub Tank Useful on a Land Cruiser?

The sub fuel tank in certain Toyota Land Cruisers plays a crucial role in extending the SUV’s range, especially in off-road and overland scenarios.

Advantages of the Sub Tank

• Extended Range – Increases total fuel capacity by 20-45 liters depending on the model.
• Remote Driving – Ideal for outback, desert, or cross-country routes where fuel stops are rare.
• Convenience – Lets you switch tanks via a button on the dash.
• Redundancy – Provides backup fuel if the main tank runs dry or fails.

This feature is especially valued in export diesel models like the 70 and 80 Series used in Australia, Africa, and the Middle East.
