Natural gas truck maintenance has great benefits that save costs.
With these saved costs, the total planned maintenance costs for a natural gas truck are equivalent to those of a diesel truck, even with the 3 year safety inspection requirement for a natural gas truck.
Add to that fuel economy of up to 35%, your operating costs will be significantly reduced.
