Wise Gas, Inc. receives a large number of inquiries daily, ranging from individual questions about vehicle conversions and refueling to detailed questions from public agencies, municipalities and corporations regarding many of the same.

Below is a sampling of some of the most frequently asked questions, arranged by topic for your convenience.  We still welcome your calls and emails, however for those browsers that are seeking a more immediate answer, this page may be helpful in guiding you.

More detailed information on most topics is readily available on our Education and Information page.  You are welcome to share any and all information we have provided, on the condition that you give credit where credit is due to Wise Gas, Inc. and that you DO NOT alter or edit and portion of this website in any way, including removing logos, photos, etc.  Our information has already been "borrowed" by other companies and passed off as their own, and the Wise Gas team members who spent so many hours creating it get a little...well, irritable about it.

F.A.Q. by Topic



  • What is it you "do"?
    • A lot, actually.  Your best answer to this question is going to be found under the page "Our Products, Services & Capabilities".  The short answer is that if it is related to CNG as an alternative fuel in Florida - we do everything.
  • Why does Wise Gas, Inc. promote CNG?  Are you opposed to bio-diesel, ethanol and hybrid electric vehicles?
    • We stand behind CNG because after exhaustive research into alternative fuels, we believe CNG to be the best choice.  Having stated that, we believe there is no "silver bullet" to solving the national fuel crisis and we firmly support other alternative fuels.  It is our position that fuel should be a matter of consumer choice - every driver should have the option of selecting the alternative fuel vehicle that s/he believes is best for them and our goal is simply to ensure CNG is a viable option across our home state of Florida, and ultimately the nation.
  • Do you only work in Florida?
    • Not at all.  Wise Gas works nationally across the U.S.A. 
  • How long have you been in business?  What experience do you have?
    • Wise Gas, Inc. was officially incorporated in July 2008.  Our team has a combined total of several decades of experience in every area of our business. 
  • Isn't CNG dangerous?  Will my car "blow up"?
    • Not likely.  In fact, Compressed Natural Gas is actually proven to be safer than either gasoline or diesel fuel.  It has a higher "flash point" which means it doesn't ignite as easily as other fuels because it requires a very specific gas-to-air combination to be a danger.  CNG is lighter than air, so it dissipates rather than pools and it is stored in cylinders which are subjected to extreme tests before receiving approval - including bullets, bonfires and multiple impact tests involving cranes.  Compared to a more flammable liquid stored in a 1/16th inch thick stamped metal gasoline tank - CNG is far safer.  Unless you are using improper, uncertified equipment (which Wise Gas, Inc. does NOT use or endorse) - you won't have to worry!  You can learn more about CNG and Safety on our Education and Information page.
  • What about the environment?
    • The short answer is a 21-26% reduction in Greenhouse Gas Emissions.

      The following information is available from the U.S. Department of Energy (view at http://www.afdc.energy.gov/afdc/vehicles/emissions_natural_gas.html)

      Natural Gas Emissions
      Natural gas is stored on vehicles in two forms: compressed and liquefied. Tailpipe emissions are the same for either form of natural gas in light-duty vehicles (LDVs), and evaporative emissions are negligible for both forms since the fuel systems in natural gas vehicles were built to accommodate their extremely low evaporation temperature and pressure.

      Light Duty Vehicles
      Compressed natural gas (CNG) and liquefied natural gas (LNG) can be used as a replacement for gasoline in light-duty vehicles (LDVs). The Argonne National Laboratory (ANL) report, A Full Fuel-Cycle Analysis of Energy and Emissions Impacts of Transportation Fuels Produced from Natural Gas (PDF 922 KB), combined emissions data from 14 primary studies to determine the effects of natural gas fuels on LDV tailpipe emissions. The weighted results were used in their GREET-based analysis and are illustrated in the table below.

      Pollutants Found to Be Significantly Related to CNG Use When Compared to Reformulated Gasoline in Clean LDVs
      Pollutant Percent Reduced
      Volatile Organic Compounds (VOC) 10%
      Carbon Monoxide (CO) 20-40%
      Oxides of Nitrogen (NOx) 0%
      Particulate Matter (PM) 80%
      Methane -400% (increase)

      Fleet Studies

      A National Renewable Energy Laboratory (NREL) fleet study of 13 vans in the Denver Super Shuttle fleet found that dedicated CNG vans have significantly lower emissions of nonmethane hydrocarbons (NMHC), CO, and NOx than gasoline or bi-fuel vans operated on CNG or gasoline. Another NREL study of 20 taxicabs also found that CNG reduced NMHC and CO but did not find any reduction in NOx.

      Heavy-Duty Vehicles

      CNG can also replace diesel fuel in heavy-duty vehicles (HDVs). Due to the variety of HDVs and drive cycles that natural gas can be used for, emissions benefits must be assessed for multiple working fleets. NREL and the University of West Virginia (UWV) studied numerous fleets as part of its Alternative Fuel Truck Evaluation Project.
