Exploring Internal Combustion Fuel Options

Choosing an internal combustion (IC) forklift can be a smart way to balance power, performance, and return on investment. But selecting an IC forklift is only part of the decision—you also need to choose the right fuel type for your operation.

Each fuel option—liquid propane (LP), diesel, or dual fuel offers distinct advantages depending on your facility, application, and infrastructure. Understanding these differences will help you select the best solution for efficiency, cost, and long-term performance.

LP is ideal for customer locations that do not have dual fuel, diesel, or refilling stations readily available. If you’re purchasing forklifts for a new facility, LP has the lowest initial cost since you only need to purchase LP tanks and find a place to store them.

• Lower upfront infrastructure costs - no permanent fueling station needed
• Easy to exchange empty tanks compared to diesel and gas 
• Suited for a wide range of applications

Best Fit For: Operations needing flexible indoor and outdoor use, as well as those that don't require existing fuel infrastructure. 

Diesel fuel is highly efficient and can offer longer run times in general compared to other fuel types, while also providing increased acceleration over their internal combustion counterparts.

• Typically more fuel efficient over long shifts
• Strong torque for heavy loads and continuous operation
• Longer run times compared to other fuel options

Best Fit For: Outdoor applications such as lumber yards, construction sites, and heavy duty material handling 

Dual fuel offers the flexibility of operating on both gasoline and LP, allowing operators to switch between fuel types based on availability and application needs. The versatility can help minimize downtime by ensuring a backup fuel option is always accessible. While they require the infrastructure to support both fuel types, they can provide operational convenience for mixed-use fleets. 

• Flexibility to switch between gasoline and LP fuel types
• Reduces downtime by switching LP when gasoline or LP runs out
• Consistent performance across varying applications  

Best Fit For: Operations that want flexibility or have access to multiple fuel sources, and they don’t have to commit to a single option. 

Selecting the right internal combustion forklift fuel doesn’t just come down to preference. It directly impacts your productivity, operating costs, and equipment performance. By aligning your fuel choice with your application, facility setup, and long-term goals, you can build a fleet that supports efficient and reliable operation.

Liquid propane (LP) is the most common due to its versatility and low infrastructure requirements.

LP forklifts can be used indoors with proper ventilation. Diesel and gasoline forklifts are generally better suited for outdoor use. 

Diesel forklifts typically offer better fuel efficiency and longer run times, especially in outdoor applications.
