The CAT 279C and Its Engine Platform
The Caterpillar 279C is a compact track loader introduced in the late 2000s as part of Caterpillar’s C-Series lineup. Designed for grading, loading, and material handling in tight spaces, the 279C features a powerful turbocharged diesel engine—shared with its sibling, the 289C. This engine delivers approximately 82 horsepower and supports a hydraulic system capable of powering demanding attachments like trenchers, augers, and mulchers.
Caterpillar, founded in 1925, has long been a leader in compact equipment, and the 279C was engineered to meet the needs of contractors working in urban development, landscaping, and utility installation. Thousands of units were sold across North America, and the model remains popular in rental fleets and private ownership due to its reliability and performance.
Typical Fuel Burn Rates
Under full throttle and continuous operation, the CAT 279C consumes approximately 3.0 gallons per hour, which translates to 11.35 liters per hour. This figure assumes high-load conditions such as grading or material movement with hydraulic attachments engaged. When operated using the foot throttle or under intermittent load, fuel consumption drops significantly.
Terminology Explained
While 11.35 liters per hour may seem high, it’s consistent with other machines in its class. For example:
Optimizing Fuel Usage
Operators can reduce fuel consumption through several strategies:
In Houston, a contractor operating a CAT 289C noticed high fuel costs during a summer grading project. By switching from full throttle to foot throttle during material placement and reducing idle time between loads, he cut fuel usage by nearly 20% over two weeks. The savings allowed him to extend the project budget and invest in a new grading attachment.
Maintenance Recommendations
The CAT 279C compact track loader consumes roughly 3 gallons or 11.35 liters of fuel per hour under full load. While this rate is typical for its class, operators can significantly reduce consumption through throttle management, maintenance, and operational discipline. With proper care, the 279C delivers powerful performance without excessive fuel costs, making it a dependable choice for compact earthmoving tasks.

This figure assumes high-load conditions such as grading or material movement with hydraulic attachments engaged. When operated using the foot throttle or under intermittent load, fuel consumption drops significantly.
Terminology Explained
- Foot Throttle: A pedal-operated throttle that allows variable engine speed based on operator input, improving fuel efficiency during light-duty tasks.
- Full Throttle: Maximum engine RPM, typically used during heavy lifting or continuous hydraulic operation.
- Fuel Burn Rate: The volume of fuel consumed per hour, often used to estimate operating costs.
While 11.35 liters per hour may seem high, it’s consistent with other machines in its class. For example:
- Hitachi EX130 excavator: Similar fuel burn under load, despite being a different machine type.
- Bobcat T300: Slightly lower consumption due to smaller engine and hydraulic output.
Optimizing Fuel Usage
Operators can reduce fuel consumption through several strategies:
- Use foot throttle during light tasks Avoid full RPM when idling or repositioning.
- Maintain clean air and fuel filters Clogged filters reduce efficiency and increase fuel burn.
- Monitor tire and track tension Improper tension increases resistance and engine load.
- Limit unnecessary idling Shut down the engine during extended pauses.

Maintenance Recommendations
- Check fuel filters every 250 hours
- Inspect throttle linkage quarterly
- Log fuel usage weekly to identify trends
- Use high-quality diesel to prevent injector fouling
