Which Cars Come With a Sub Fuel Tank?
Vehicles with a sub-fuel tank are designed for extended driving range and improved fuel management. A sub tank, also known as an auxiliary fuel tank, works alongside the main tank to store extra fuel, making it especially useful for long-distance travel and remote area driving.
Off-Road & Adventure Vehicles
- Toyota Land Cruiser 70 Series – Many variants in markets like Australia and Africa come standard with a secondary fuel tank.
- Toyota Land Cruiser 80 Series – Select trims and regions offered factory-installed sub tanks for extended range.
- Toyota Land Cruiser 100 Series – Available in certain export markets with integrated auxiliary tanks.
- Nissan Patrol (Y60/Y61) – Known for having dual-tank systems in heavy-duty and expedition-ready trims.
Utility & Commercial Vehicles
- Toyota Hilux – Some models in mining and rural service configurations include sub tanks.
- Ford Ranger (special editions) – Certain markets offer auxiliary fuel tanks for work and travel needs.
- Isuzu D-Max – Optional sub tank setups available in some utility-focused variants.
Touring & Expedition Builds
- Overlanding conversions – Aftermarket auxiliary tanks are common in expedition-prepared SUVs and pickups.
- Camper trucks – Custom rigs often integrate large sub tanks for long stretches without fuel stations.
- Safari and desert vehicles – Frequently equipped with sub tanks to handle remote routes.
Benefits of Sub Fuel Tanks

Cars with a sub-fuel tank are most often found in heavy-duty, off-road, and commercial applications where reliability, endurance, and range are critical for the vehicle’s purpose.
