Why Does the Toyota Land Cruiser Have Two Tanks?
The Toyota Land Cruiser two-tank system is designed to extend driving range and provide flexibility for long-distance or remote travel. Many Land Cruiser models, especially those built for markets like Australia, Africa, and the Middle East, feature a main fuel tank and a sub or auxiliary tank to support off-road and expedition use.
Purpose of the Dual Tank Setup
This system offers practical benefits for drivers who frequently travel far from fuel stations or operate in rugged environments.
- Extended Range – Increases total fuel capacity for long journeys.
- Fuel Management – Allows switching between tanks to control usage.
- Emergency Backup – Provides a reserve if the main tank runs low.
How It Works
The Land Cruiser’s dual tank system can operate automatically or manually, depending on the model and year.
- Automatic Transfer – Some systems feed fuel from the auxiliary tank into the main tank without driver input.
- Manual Switching – Uses a dash-mounted switch or lever to select the active tank.
- Separate Fill Points – Certain models have individual filler caps for each tank.
Benefits for Off-Road & Remote Use
Dual tanks give Land Cruiser owners the confidence to explore areas where fuel availability is limited.
- Overlanding Capability – Ideal for expeditions across remote terrain.
- Reduced Fuel Stops – Saves time during long hauls.
- Improved Weight Balance – Strategic tank placement helps maintain stability.
The Toyota Land Cruiser two-tank system is a proven solution for increasing range, improving travel flexibility, and providing peace of mind in challenging environments. It’s one of the features that make the Land Cruiser a favorite for serious adventurers.
