A semi truck can hold 100 to 300 gallons of fuel
Semi truck fuel tanks typically range from 100 to 300 gallons, with most trucks carrying two tanks that total 150 to 300 gallons. The exact capacity depends on the truck model, with long-haul trucks generally having larger tanks than local delivery trucks.
Factors affecting fuel tank capacity
- Truck size and model
- Intended use (long-haul vs. local)
- Manufacturer specifications
- Available space in chassis design
Fuel capacity comparison by truck type
| Truck Type | Fuel Capacity | Typical Use |
|---|---|---|
| Day cab | 100-150 gallons | Local delivery |
| Regional hauler | 150-200 gallons | Regional routes |
| Long-haul tractor | 200-300 gallons | Cross-country routes |
Fuel efficiency considerations
Semi trucks typically get 6-8 miles per gallon. With a full tank, a truck can travel 600-2400 miles depending on tank size and driving conditions. Larger tanks allow for fewer refueling stops on long routes.
Cost to fill a semi truck
At current diesel prices averaging $3-4 per gallon, filling a semi truck costs between $300 and $1200. The price varies based on local fuel costs and current market rates.
