Introduction to the Caterpillar D8H
The Caterpillar D8H is a classic and powerful track-type tractor widely recognized for its rugged construction and strong performance in earthmoving tasks. It is equipped with a turbocharged diesel engine, known as the Cat 35-series engine, delivering approximately 235 horsepower.
Typical Fuel Consumption Rates
Fuel consumption in the Caterpillar D8H reflects the machine’s powerful operational capability and the demanding nature of heavy earthmoving tasks. While consuming around 13 to 14 gallons per hour under full load, efficient operation, regular maintenance, and appropriate task management can curtail fuel use, enhancing economy and productivity on the jobsite. The D8H remains a reliable powerhouse with fuel efficiency balanced against its performance requirements.

Typical Fuel Consumption Rates
- Under constant full load conditions such as deep ripping or heavy earth pushing, the D8H is reported to consume fuel at rates between 13 to 14 gallons per hour.
- Lighter activities like surface grading or clean-up work typically reduce fuel usage significantly but exact gallons per hour depend on job demands and operator technique.
- Fuel efficiency varies based on terrain, machine condition, hydraulic load, and operator skill level.
- Load Intensity: Tasks requiring high power output, such as ripping hard ground, drive higher fuel burn.
- Hydraulic System Load: Heavy usage of hydraulic attachments adds to engine load thereby increasing fuel use.
- Operating Conditions: Soft soils, steep grades, or excessive idling impact consumption rates.
- Maintenance Status: Well-maintained engines with clean filters and proper fluid levels operate more efficiently.
- Operator Behavior: Smooth throttle control and efficient maneuvering reduce fuel waste.
- The fuel tank capacity typically ranges around 100 to 110 gallons (approximately 380-417 liters) on units like the D8H, which supports several hours of continuous operation under heavy load before refueling is necessary.
- Use correct engine RPM and transmission gearing for the task to avoid excessive fuel use.
- Regularly service air and fuel filters to maintain optimal engine performance.
- Avoid extended idle times when not actively working.
- Monitor hydraulic system efficiency and address leaks or worn components quickly.
- Full Load: Operating condition where the engine is producing maximum or near-maximum power output.
- Turbocharged Diesel Engine: Engine equipped with a turbocharger that forces more air into the combustion chamber to increase power.
- Hydraulic Load: The demand placed on the hydraulic system by attachments or implements, affecting engine power requirement.
- Idle Time: Periods when the engine is running but the machine is not actively performing work.
