CNG Coach Sunlong SLK6102

A: In terms of maintenance costs, CNG models actually have an advantage. On one hand, CNG fuel prices are usually 30% to 40% lower than diesel, significantly reducing daily fuel expenses.
On the other hand, CNG burns more completely, resulting in less engine carbon buildup. This allows for longer oil change intervals-up to 15,000 kilometers compared to the typical 10,000 kilometers for diesel buses. Additionally, parts like spark plugs and valves wear out more slowly and need replacement less often.
Overall, the annual maintenance cost of a CNG bus is 15% to 20% lower than that of a comparable diesel model, making it more economical for long-term operation.
