Natural gas provides savings on operating and maintenance costs of vehicles.
Natural gas is more environmentally friendly and safer to use than most other fuels. Natural gas is available and convenient . Natural gas is formed by the decay of organic matter. Natural gas reserves or deposits come from large quantities of plant and animal remains that have accumulated between layers of sediment on the bottoms of lakes and oceans over millions of years. The pressure from the layers of sediment and the heat from the earth's core convert the organic materials into natural gas, petroleum and coal.
