CNG of OKC is fully dedicated to the natural gas industry. We believe that natural gas is today's American energy answer that will stop the dependency on foreign oil. As gasoline prices continue to rise, American interest in CNG is rising accordingly, and we are here to help! Using state of the art technology, we are able to convert most standard engines (gasoline or diesel) to run on CNG. We leave your existing fuel system intact, while installing our hybrid bi-fuel CNG system. Once you make the switch to CNG, your vehicle will become a bi-fuel NGV (Natural Gas Vehicle). You will then enjoy paying 40-70% less each time you fill up your tank. Your vehicle will generate up to 80% less emissions and be capable of going up to 20,000 miles between oil changes.
