Bigger Machines Use More Fuel but Offer More Productivity
When choosing a skid steer loader, one of the most common concerns for first-time buyers is fuel consumption. The question often arises: How much more fuel does a 70 hp machine use compared to a 45 hp unit? While the answer depends on workload, terrain, and operating habits, the general rule is that higher horsepower machines consume more fuel, especially when used at full capacity. However, they also complete tasks faster and more efficiently.
For example, a 92 hp track loader may burn 17 to 19 gallons per day under moderate load, such as operating at half throttle. In contrast, a 50 hp machine like the Cat 216 might consume 7 to 8 liters per hour, which translates to roughly 15 to 17 gallons over a full 8-hour shift depending on the task. These figures vary based on whether the machine is digging, grading, or idling.
Gas vs Diesel Engines
Another key consideration is engine type. Diesel engines are generally more fuel-efficient than gasoline engines, especially under heavy load. They also offer better torque at low RPMs, which is ideal for earthmoving. Diesel engines are more tolerant of long idle periods and cold starts, whereas gasoline engines are prone to carburetor issues, fuel degradation, and ignition system corrosion if left unused for extended periods.
In terms of safety and efficiency, diesel fuel is less flammable and more stable in storage. Older gas-powered skid steers often feature air-cooled engines with outdated designs, making them less desirable for modern applications.
Fuel Cost vs Work Output
Rather than focusing solely on fuel burned per hour, it's more useful to consider work done per gallon. A larger machine may burn more fuel, but if it moves twice the material in the same time, it’s more cost-effective. This is especially true for commercial operators who measure productivity in terms of yards moved, trucks loaded, or hours saved.
For example, a contractor using a 90XT Case skid steer reported minimal fuel use because the machine was rarely operated above idle. In contrast, a smaller machine might need to run at full throttle to achieve the same output, increasing wear and fuel consumption.
Choosing the Right Machine for Your Needs
Before deciding on horsepower, consider the following:
Conclusion
Fuel consumption is a valid concern, but it should be weighed against productivity, engine type, and long-term operating costs. Diesel engines offer better efficiency and reliability, while larger machines deliver more work per hour despite higher fuel use. By evaluating your workload, terrain, and attachment needs, you can choose a skid steer that balances performance with operating cost—ensuring your investment pays off in both time and fuel.

Choosing the Right Machine for Your Needs
Before deciding on horsepower, consider the following:
- Rated Operating Capacity (ROC): How much weight do you need to lift?
- Lift Path: Vertical lift is better for loading trucks; radial lift suits digging and grading.
- Hydraulic Flow: High-flow attachments like mulchers or trenchers require more hydraulic power.
- Access and Transport: Smaller machines are easier to tow and maneuver in tight spaces.
