Review of the Autogas Standard

The Fuel Standard (Autogas) Determination 2003 (Autogas Standard) commenced on 1 March 2004 to regulate the quality of autogas (liquefied petroleum gas or LPG) supplied in Australia for use in motor vehicles. A technical discussion paper considering a review of the Autogas Standard was released for public comment in 2010. The paper considered amending the Autogas Standard to harmonise with the updated European standard for autogas (EN 589:2008) and to address potential operability and emissions performance issues with existing limits of some parameters.

Following feedback received on the paper, and further consultation with the Fuel Standards Consultative Committee, fuel suppliers, vehicle manufacturers and the LPG industry, the following amendments to the original Autogas Standard have now been made:

  • reduction in the maximum sulfur limit from 100 mg/kg to 50 mg/kg, effective from 1 December 2013
  • reduction in the maximum residue on evaporation limit from 100 mg/kg to 60 mg/kg, effective from 1 December 2013
  • updated testing methods for water, sulfur and odour parameters to harmonise with the testing methods in the European standard for autogas and/or for safety reasons associated with conducting the testing method.

Further information on the amendments may be found in the Explanatory Statement to the Fuel Standard (Autogas) Amendment Determination 2013
