What Is the Sub Tank Capacity in a Land Cruiser?
The sub tank capacity in a Land Cruiser varies depending on the model and market, but it typically ranges from 30 to 90 liters. This auxiliary fuel tank works alongside the main tank to extend driving range, making it ideal for long-distance travel, overlanding, and remote-area exploration.
Purpose of the Sub Tank
The sub tank is designed to store extra fuel and supply it to the main tank when needed, ensuring extended travel without frequent refueling stops.
- Increased Range – Allows for longer trips between fuel stations.
- Fuel Management – Drivers can control when to use the auxiliary fuel.
- Off-Road Advantage – Necessary for remote trips where fuel is scarce.
Capacity by Model
Different Land Cruiser generations and trims have varying sub-tank sizes, often depending on intended market use.
- 70 Series – Commonly equipped with 90-liter sub tanks for extended-range capability.
- 80 Series – Typically features sub tanks around 45 to 50 liters.
- 200 Series – Some variants offer 45- to 60-liter auxiliary tanks.
Using the Sub Tank
Many Land Cruisers have a dashboard switch or control to transfer fuel from the sub tank to the main tank.
- Manual Transfer – Requires the driver to activate the pump or valve.
- Automatic Systems – Some models switch over when the main tank runs low.
- Indicator Lights – Show fuel levels for both tanks.
The sub tank capacity in a Land Cruiser plays a key role in its reputation as a dependable long-range vehicle, giving drivers confidence in remote or fuel-limited regions.
