Image referencing CNG for article about saving money with Compressed Natural Gas for fleets and drivers interested switching or using CNG fuel from diesel.



Whether you have a fleet of 5 or 500 vehicles, compressed natural gas (CNG) is a viable option worth considering. While the costs of petroleum fuels continue to rise, CNG is stable and significantly cheaper than conventional fuels.

Stop paying top dollar at the pump! Find out how much money you can save by converting your fleet to compressed natural gas (CNG).



Less Fuel Cost & More Savings

Compressed natural gas (CNG) is an affordable alternative when compared to gasoline or diesel fuel. CNG can cut fuel costs by about 50% while delivering the same power and performance. In addition, with fuel emissions standards rising in cities more fleet organizations are seeing the value natural gas can add to their budgets.

Meanwhile, record U.S. natural gas production – a landmark study showed supply far exceeds government forecasts – and storage levels assure reasonable prices for the foreseeable future. In the past five years, natural gas prices have risen much less than many other commodities.

Savings with New NGVs

Natural gas vehicles typically cost more than gasoline or diesel vehicles. This is largely due to the cost of high-pressure and insulated fuel tanks, which are necessary to store CNG or LNG. However, the cost of natural gas fuel is now $0.50 to $1.00 less per gallon. The savings in fuel costs can translate into significant savings over the life of a vehicle, depending on fuel efficiency and the number of miles driven. The greatest savings are currently being seen in heavy-duty, high mileage fleets. These vehicles consume enough fuel for owners and operators to see a pay back in as little as 18–24 months. As the price of fuel tanks comes down, light-duty passenger vehicles will become less expensive and also will enjoy a shorter payback period.

Facts About Natural Gas Vehicles

With proven reserves of domestic natural gas soaring and our dependence on foreign oil as burdensome as ever, it only makes sense to start using our clean, inexpensive, and abundant natural gas as a vehicle fuel. Natural gas vehicles (NGV) are good for our economy, our environment, and your bottom line. Whether you are an individual or a fleet manager, never before have there been so many natural gas products and services available, spurred by unprecedented industry investment and government incentives. Read on to learn more about the many benefits of NGVs.


Vehicle Conversions


Retrofitting Diesel Vehicles to Natural Gas Vehicles.
Natural gas vehicle conversions provide alternative fuel options beyond what is available from original equipment manufacturers (OEMs). Qualified service retrofitters (QSRs) can economically and reliably convert many light- and medium-duty vehicles for natural gas operation. Natural gas engines and fueling systems are also available for some heavy-duty vehicles.

NGVs America offers information on light-, medium-, and heavy-duty natural gas vehicles and engines available directly from OEMs or via conversion systems certified by the U.S. Environmental Protection Agency (EPA) or the California Air Resources Board. It also provides manufacturer and QSR contact information.

Vehicle conversions in the United States require EPA certification, and a QSR should perform the installation. See the AFDC's Conversions page for information on regulations, codes, and standards that apply to all alternative fuel and advanced vehicle conversions.

The upfront costs to convert fleet vehicles to natural gas can be offset by lower operating and maintenance costs over the lifespan of the vehicles. The payback period depends on the fleet’s average distance traveled, required fueling infrastructure costs, and other considerations.
