The cars with two fuel tanks are usually designed for extended range, specialized work, or off-road applications. While dual fuel tanks are more common in trucks and commercial vehicles, some passenger vehicles and SUVs also use them to increase driving distance without frequent refueling.
Pickup Trucks With Dual Tanks
- Ford F-Series (older models) – Many F-250 and F-350 trucks from the 1980s and 1990s came with two tanks for long-distance hauling.
- Chevrolet and GMC heavy-duty pickups – Select models from past decades offered dual fuel tanks for work and towing purposes.
- Dodge Ram (early generations) – Some variants featured dual tanks to cater to construction and agricultural needs.
Utility & Off-Road Vehicles
- Toyota Land Cruiser (certain models) – Versions like the 70 Series and some 80 Series trims included sub tanks for long-range travel.
- Nissan Patrol – Offered with a factory-installed auxiliary tank in certain markets for desert and expedition use.
- Jeep J-Series trucks – Older Jeep pickups sometimes came with dual tanks for extended utility.
Commercial & Specialty Vehicles
- Ambulances and rescue vehicles – Often equipped with dual tanks to stay operational for long shifts without refueling.
- Delivery trucks – Use extra tanks to cover wide routes efficiently.
- Expedition vehicles – Custom overland builds frequently add secondary tanks for remote travel.
Benefits of Two Fuel Tanks
- Extended driving range – Ideal for remote travel and long work shifts.
- Fuel management flexibility – Allows switching between tanks to manage weight and consumption.
- Emergency backup – Ensures a reserve supply in case one tank runs dry.
The cars with two fuel tanks appeal to drivers who value range, reliability, and operational efficiency. While less common in modern passenger cars, they remain a key feature in trucks, off-roaders, and specialized work vehicles.
