Why Does the Land Cruiser Have Two Fuel Tanks?

Certain Toyota Land Cruiser models are built with a dual fuel tank setup that includes a main tank and a sub- or auxiliary tank. This design is aimed at increasing driving range, reliability, and versatility in demanding environments.

Extended Driving Range

One of the main reasons for having two fuel tanks is to travel longer distances without needing to refuel. In remote regions or during extended off-road trips, fuel stations can be few and far between. The extra capacity allows Land Cruiser owners to cover more ground between stops.

Off-Road & Remote Travel Capability

The Land Cruiser is often used in challenging terrains such as deserts, mountains, and rural areas. A dual tank setup ensures drivers have a backup fuel supply if the main tank runs low, adding an extra layer of security in areas where running out of fuel could be dangerous.

Better Fuel Management

With two tanks, drivers can choose when to transfer fuel from the sub tank to the main tank. This can help manage weight distribution and allow the use of different fuel grades if necessary.

Market & Model Variations

Not all Land Cruisers come with dual tanks. They are most common in utility-oriented models like the 70 Series and in certain markets such as Australia, Africa, and the Middle East, where long-range travel is common. Some 80, 100, and 105 Series models also offer this feature in specific configurations.

The Toyota Land Cruiser’s dual fuel tank setup is designed for endurance, safety, and flexibility. It is especially valuable for off-road enthusiasts, overlanders, and anyone who travels in areas with limited refueling options.
