This document summarizes Kwik Trip's experience with natural gas vehicles. It shows that over the lifetime of a vehicle, the savings from lower fuel and operating costs for CNG vehicles outweighs the higher initial capital costs. For example, a CNG tractor costs $45,000 more up front but saves $137,607 in fuel over its lifetime. The document also provides an overview of Kwik Trip's fleet operations and maintenance practices for CNG vehicles. It demonstrates how switching part of the fleet to CNG can provide significant cost savings long-term.
