1. Autogas is typically a mixture of propane and butane but can be all propane.
  2. The chemical formulas for propane – C3H8 – and butane – C4H10 – are different.  However,the formula for butane and isobutane are the same. Isobutane (i-butane) is an isomer of butane, so it has a different arrangement of its atoms.

  5. LPG burns faster and cleaner than any forms of bio-fuel.
  6. LPG is naturally odourless, colourless and tasteless.
  7. LPG measurement is done in weight, liquid volume, gaseous volume, energy content and pressure.
  8. LPG gas has a higher calorific value versus natural gas.
  9. LPG gas comes from natural gas processing and petroleum refining.
  10. LPG gas is frequently used for fuel in heating, cooking, hot water and vehicles, as well as for refrigerants, aerosol propellants and petrochemical feedstock.
