CNG Interstate is a compressed natural gas fueling station and light-duty vehicle service facility located on the south side of Oklahoma City, serving fleet operators and individual vehicle owners who run bi-fuel or dedicated natural gas engines.
CNG Interstate operates as a public access fueling point combined with basic automotive maintenance for vehicles equipped to run on compressed natural gas. The station caters to both commercial fleets and private owners in a region where natural gas vehicle infrastructure remains sparse. Unlike traditional gasoline stations, the facility requires customers to fuel via attended pump service, and vehicles must be equipped with factory or certified aftermarket CNG systems. The operation is smaller in scale than Oklahoma City's major fuel networks but fills a deliberate niche: it is one of the few public CNG stations accessible to non-commercial customers across the metro area.
CNG pricing at Interstate tracks below gasoline per energy equivalent but fluctuates with wholesale natural gas costs. Current pricing hovers in the range of $1.80 to $2.40 per gallon equivalent (GGE), though this shifts monthly. Call ahead to confirm current rates, as natural gas commodity pricing changes more frequently than gasoline. A typical fill on a bi-fuel sedan costs $8 to $15, compared to $35 to $50 for gasoline in the same vehicle. The station offers basic maintenance services: compressor diagnostics, pressure regulator inspection, and fuel system checks specific to CNG equipment. These services are essential because natural gas systems require different diagnostic tools than conventional fuel systems, and most general repair shops cannot service them safely.
Oklahoma City has no major competitor CNG stations operating as public access points. Drivers in the metro area can access natural gas at scattered fleet-only facilities or through private networks, but CNG Interstate is among the few open-to-the-public options. For those committed to natural gas as a primary fuel, the nearest alternative fueling infrastructure lies in Tulsa (roughly 100 miles north) or Dallas (200 miles south). This geographic isolation means CNG Interstate attracts long-haul drivers and fleet operators who cannot afford frequent deviation to find fuel. Conversely, drivers with bi-fuel vehicles who use CNG occasionally for cost savings may find the drive worthwhile only if they live on the south side. Traditional repair shops cannot match CNG Interstate's expertise in pressure systems, regulator function, or fuel-line integrity checks; a general mechanic will refer CNG work elsewhere, making this station essential rather than optional for owners of these vehicles.
CNG Interstate suits fleet managers running CNG trucks or vans, owner-operators in delivery or service trades who refuel regularly, and individual drivers with bi-fuel sedans living south of Oklahoma City. Owners of bi-fuel Honda Civics or Ford F-150s who want to reduce fuel costs on predictable routes find the station practical. Those living north of downtown or in the suburbs may find the drive to refuel uneconomical unless they pass the location on regular routes. Standard gasoline vehicle owners have no reason to visit; the station does not service them. Drivers new to natural gas vehicles benefit from the facility's diagnostic capability, which identifies leaks or regulator wear before they become safety issues.
Arrive with your vehicle's fuel door accessible and your CNG system valves (fuel shutoff and service valve) visible to the attendant. An attended pump operator will inspect your vehicle's CNG fitting for compatibility, then guide the fueling nozzle into your receptacle. The process takes 5 to 10 minutes per vehicle. If you need a system diagnostic, inform the attendant on arrival; pressure testing and regulator inspection add 30 to 45 minutes. First-time customers should expect a brief orientation on how the station's specific pump connector seats into your vehicle's fill port, as designs vary by manufacturer.
CNG Interstate operates Monday through Friday, 8:00 a.m. to 5:00 p.m., and is closed weekends and major holidays. Verify current hours before a visit, as staffing patterns can shift seasonally. The facility has dedicated parking for 4 to 6 vehicles fueling or in service. Public restroom access is available. Cash and credit cards are accepted, though fleet accounts with prepaid billing are standard for regular customers.
A working knowledge of natural gas vehicle infrastructure in Oklahoma City is incomplete without recognizing CNG Interstate as the primary refueling anchor for the metro area's modest but growing CNG fleet base.
