How Fuel Efficient Are Mini Trucks? What You Need to Know

With gas prices on the rise, fuel economy is one of the biggest considerations when buying a utility vehicle. If you’re wondering, “How fuel efficient are mini trucks?”, the answer might surprise you. Thanks to their compact size, lightweight construction, and small-displacement engines, Japanese mini trucks are some of the most fuel-efficient utility vehicles available.

Let’s break down their typical MPG, what affects their efficiency, and how you can get the most out of every gallon.

1. Average Mini Truck MPG

Most Japanese mini trucks, including popular models like the Daihatsu Hijet Jumbo and Hijet Deck Van, are equipped with 660cc gas engines. These engines are designed for efficiency without sacrificing utility.

Average fuel economy:

• 35–45 MPG depending on driving conditions, load weight, and modifications
• Some older carbureted models may achieve closer to 30–35 MPG
• Newer fuel-injected models tend to get better mileage

Compared to many side-by-sides or full-size pickups that average 15–25 MPG, mini trucks offer exceptional fuel savings.

2. What Affects Mini Truck Fuel Efficiency?

Several factors can influence your mini truck’s fuel performance:

• Driving Style: Aggressive acceleration or frequent idling can reduce MPG.
• Tire Type: Larger or off-road tires create more rolling resistance.
• Terrain: Hills and off-road use demand more power and burn more fuel.
• Load Weight: Hauling heavy cargo affects fuel economy just like any vehicle.
• Maintenance: Clean air filters, proper tire pressure, and regular oil changes keep your engine running efficiently.

3. How to Improve Fuel Efficiency

Want to get the best mileage possible? Here are a few tips:
✅ Keep your tires properly inflated
✅ Use lightweight wheels and aerodynamic accessories
✅ Avoid excessive idling or heavy loads when unnecessary
✅ Upgrade to a performance air filter or fuel injector cleaner
✅ Stick to regular maintenance intervals

4. Fuel Economy Compared to UTVs and Pickups

While UTVs may seem like a comparable option, they often use larger, less efficient engines and get only 12–20 MPG. Full-size pickups average 15–25 MPG and cost far more to fuel and maintain.

For daily work, property management, or off-grid use, mini trucks deliver a great balance of performance and cost savings.
