The ONG CNG Fill Station is a public compressed natural gas fueling facility operated by Oklahoma Natural Gas, located to serve the Oklahoma City area's small but growing fleet of vehicles powered by CNG rather than gasoline or diesel. Unlike conventional gas stations, this is a single-purpose utility: it dispenses compressed natural gas at high pressure into vehicles equipped with CNG fuel systems. It sits apart from retail fuel networks because CNG vehicles remain uncommon in Oklahoma City, making access to filling infrastructure a practical constraint rather than a convenience choice.
This is a standalone fueling station dedicated exclusively to CNG. The station does not sell gasoline, diesel, or any retail products. It consists of one or more high-pressure compressor units that fill vehicle tanks directly. ONG operates it as a public access point, meaning any CNG-equipped vehicle owner can use it, though the station is not staffed; it typically operates on a card-activated, self-service model. The facility is designed to handle the specific mechanical interface required for CNG tanks, which differs entirely from gasoline nozzles.
CNG pricing in Oklahoma City follows wholesale natural gas costs and fluctuates monthly. As of late 2024, ONG's CNG price per gasoline gallon equivalent (GGE) ranges from roughly $1.50 to $2.00, though this should be confirmed directly with ONG before a visit, as pricing changes with market conditions. A typical fill-up for a vehicle with a 20-gallon equivalent tank costs between $30 and $40. The station uses a membership card or compatible payment system; new users must establish an account with ONG. Fill time is typically 3 to 5 minutes per vehicle.
CNG is not a substitute for gasoline or diesel in Oklahoma City—it is a parallel fuel system. Drivers of conventional vehicles have dozens of conventional gas station options across the metro, from major chains like Loves, Pilot Flying J, and Phillips 66 to independent stations. The choice to use CNG is not about finding a cheaper or more convenient fill-up; it is about vehicle type. CNG vehicles produce lower emissions than gasoline counterparts and offer fuel cost stability tied to natural gas markets rather than crude oil. For fleet operators, municipalities, or private owners committed to CNG, the ONG station is the only public access point in Oklahoma City. Drivers without a CNG vehicle cannot use this station under any circumstance.
CNG fueling suits fleet operators running dedicated CNG vehicles, municipal vehicle managers, and individual owners of bifuel or dedicated CNG cars and trucks. It does not suit anyone driving gasoline, diesel, hybrid, or electric vehicles. If you own a CNG vehicle, this station is essential infrastructure; without it, your vehicle cannot refuel in Oklahoma City. If you do not own a CNG vehicle, this station is irrelevant.
Approach the station with a valid CNG vehicle equipped with a fuel door compatible with the station's connector nozzle. If you are a new user, you must have an active ONG account established before your visit; set this up by phone or online. Pull up to the pump, activate your card, select the fueling pressure setting appropriate to your vehicle (your manual or dealer specifies this), and insert the nozzle into your fuel receptacle. The pump will fill until the tank reaches target pressure, then shut off automatically. Remove the nozzle, close your fuel door, and leave. Total time on-site is typically under 10 minutes.
The ONG CNG Fill Station operates 24 hours daily. Parking is available on-site for the single vehicle being fueled. The station is unstaffed and cardactivated. Before visiting for the first time, contact ONG at 405-896-7400 or visit the ONG website to confirm the station's exact location within Oklahoma City and to establish your account. Hours should not change, but the specific address and any temporary closures warrant a single phone call to avoid a wasted trip.
CNG infrastructure in Oklahoma City remains minimal, making this station the only practical fueling point for CNG vehicle owners in the area. It serves a narrow but essential role in the metro's transportation landscape.
