Why CNG?

The Advantages of Compressed Natural Gas

Cleaner for the environment

• Compressed natural gas is the cleanest burning fuel operating today. This means less vehicle maintenance and longer engine life.
• CNG vehicles produce the fewest emissions of any motor fuel.
• Dedicated Natural Gas Vehicles (NGV) have little or no emissions during fueling. In gasoline vehicles, fueling emissions account for at least 50% of a vehicle's total hydrocarbon emissions.
• CNG produces significantly less pollutants than gasoline.
• Tailpipe emissions from gasoline operated cars release carbon dioxide, which contributes to global warming. This is greatly reduced with natural gas.

Cheaper for your wallet

• Natural gas in Texas is cheaper per equivalent gallon than gasoline by an average of 15% to 50% less than gasoline.
• A federal tax deduction is also available for the cost of conversion
• A cash rebate is available from Texas Gas Service

Safer for your family

• Surveys indicate that NGVs are as safe or safer than those powered by other fuels. A 1992 AGA survey of more than 8,000 vehicles found that with more than 278 million miles traveled, NGV injury rates per vehicle mile traveled were 34% lower than the rate for gasoline vehicles. There were no fatalities reported--even though these vehicles were involved in over 1,800 collisions.

Less maintenance for your engine

• Some fleet operators have reduced maintenance costs by as much as 40% by converting their vehicles to CNG.
• Intervals between tune-ups for natural gas vehicles are extended 30,000 to 50,000 miles.
• Intervals between oil changes for natural gas vehicles are dramatically extended--anywhere from 10,000 to 25,000 additional miles depending on how the vehicle is used.
• Natural gas does not react to metals the way gasoline does, so pipes and mufflers last much longer.

CNG performance

• Natural gas gives the same mileage as gasoline in a converted vehicle.
• Dedicated CNG engines are superior in performance to gasoline engines.
• CNG has an octane rating of 130 and has a slight efficiency advantage over gasoline.
• Because CNG is already in a gaseous state, NGVs have superior starting and drivability, even under severe hot and cold weather conditions.
•  NGVs experience less knocking and no vapor locking.
