• Frequent oil and filter changes

• Higher long-term maintenance cost

CNG Dump Truck Maintenance:

• Cleaner combustion = less engine carbon buildup

• Longer engine life in many cases

• Slightly higher initial maintenance training requirement

Key Insight:

Although diesel trucks are cheaper to maintain short-term, CNG trucks often win in long-term lifecycle cost.
