CNG is an eco-friendly alternative to gasoline and diesel. It is made by compressing natural gas also known as methane to about 1% of its original volume. CNG is safer than gasoline or diesel, as it is non-toxic. it doesn’t contaminate groundwater and soil. Compressed natural gas is also quieter than regular fuels and can reduce greenhouse gas emissions by 30% compared to diesel.

Instructions to operate most public CNG dispensers:
- Turn off your engine. Do not smoke.
- Remove the vehicle’s dust cap and take the fueling nozzle off its holder.
- Align the arrows on the nozzle so they point to each other.
- Place the nozzle over the fuel receptacle and push it on.
- Rotate the lever so that the arrows point away from each other to lock the nozzle on.
- Insert your fleet or credit card and follow the instructions on the screen.
- Once payment is authorized, lift the dispenser handle, and fueling will begin.
- When the fill is complete, lower the handle to turn the dispenser off.
- To disconnect the nozzle, slowly rotate the nozzle handle 180 degrees until the arrows are again pointing to each other.
- Remove the nozzle. You may hear a slight release of pressure.
