Release time: 2025-10-28
Among the many used excavator models, the used Caterpillar CAT 320 excavator has consistently maintained high popularity. Renowned for its stable performance, durable construction, and excellent fuel economy, it is one of the most widely used models in construction, road, municipal, and gravel operations. For many buyers, the most important concerns are whether the used CAT320 offers sufficient value for money and how it performs in actual use. Chenghai will conduct a comprehensive review from three aspects: fuel consumption, operating efficiency, and maintenance costs.
Fuel Consumption Performance: Does the CAT 320’s Fuel Efficiency Still Stand Out?
Fuel consumption is one of the key concerns for users. Overall, the fuel performance of cheap used CAT320 excavators remains excellent, especially the 320D, 320DL, and 320E series.
Average fuel consumption is approximately 13–18 liters per hour (slight fluctuations depending on operating conditions).
Uses a genuine Caterpillar engine, ensuring stable combustion efficiency.
The hydraulic system offers rapid response, reducing idling waste.
For buyers engaged in long-term construction, this fuel consumption level is a significant advantage compared to other excavators in the same tonnage, and is one of the main reasons many choose the Used Caterpillar 320.
Operating Efficiency: A Balance of Speed and Stability
In actual construction, the CAT320 excavator consistently maintains industry-leading operating efficiency. Whether digging, loading, or leveling, it demonstrates stable output.
Common advantages of used equipment include:
Mature Hydraulic System
CAT’s hydraulic system offers rapid response and coordinated action, maintaining excellent power even after years of use.
Wide Range of Applicable Working Conditions
Examples include:
Earth excavation
River dredging
Sand and gravel loading
Municipal maintenance and renovation
This versatility makes the durable used CAT 320 excavator a consistently popular choice in the secondhand market.
High Boom and Stick Strength
The bucket digging force remains stable, allowing for efficient operation even in hard soil, wet soil, or mixed fill.
Maintenance Costs: Is maintenance of a used CAT320 expensive?
Many users worry about the maintenance costs of used machines, but the maintenance costs of a used CAT 320 are actually quite manageable. Its advantages come from:
Ample Parts Supply
Caterpillar has a well-established global system, making commonly used parts readily available and reasonably priced.
Items such as filters, toothed blocks, and chassis parts are readily available.
Low Failure Rate
The CAT 320’s structural design is stable; with proper maintenance, it will not experience frequent breakdowns even after years of operation.

Common maintenance items include:
Hydraulic oil change
Engine maintenance
Chassis inspection
Costs are more stable compared to other excavators in the same class, offering greater peace of mind in the long run.
Value for Money Summary: Used CAT320s remain a highly recommended choice
Considering fuel consumption, efficiency, and maintenance performance, the used Caterpillar 320 excavator still offers excellent value for money. Whether for small to medium-sized contractors or construction teams requiring long-term operation, this model provides reliable productivity and low operating costs.
Suitable for buyers who value the following advantages:
Those seeking low fuel consumption and cost savings
Those requiring machine stability and durability
Those wanting a used excavator with higher resale value
Those desiring simple maintenance and readily available parts
Therefore, considering its overall performance, the high-value used CAT 320 excavator is one of the most worthwhile models to buy in the current used excavator market.
